National Income
National Income
National income is defined as the total monetary value of all final goods and services arising out
of the productive economic activities of a country in a given period of time usually a year.
This is the same as national product and national expenditure
It is important to note the following
(i) National income considers only final goods and services
(ii) The goods and services considered are valued in monetary terms
(iii) The goods and services considered must have been produced in the given period of
time/year
(iv) The incomes considered should be received in exchange for goods or services
produced

Where net (property/factor) income from abroad is the difference between the total incomes
earned by nationals from abroad and the total incomes earned by foreigners from the country in a
given period of time
Or it refers to the difference between the total incomes that a country’s citizens and companies
remit from abroad and the total incomes that foreigners and overseas companies repatriate from
the country in a given period of time.

(6) NOMINAL NATIONAL INCOME
Nominal national income concepts are those valued at current year prices, therefore nominal
national income the total monetary value of all final goods and services arising from the
productive activities of a country in a given period of time valued at current year prices
Question ; Define Nominal GNP
NB; In the base year prices are relatively stable or constant while in the current year prices are
unstable because of inflation/deflation therefore the nominal national income figure may be over
or under estimated
Nominal national income /GDP
Real national income/GDP = x 100
Price index
TERMINOLOGY INTERPRETATION
GROSS Including value of depreciation
NET Excluding value of depreciation
DOMESTIC Produced within the country(by nationals and foreigners)
NATIONAL Produced by the nationals(within and out of the country)
FACTOR COST Valued at prices paid for the factors of production
MARKET PRICES Valued at prices paid for final goods and services
REAL Valued at base year prices
NOMINAL Valued at current year prices

Adjustment from national income at market prices to national income at factor cost
They market prices paid for products include indirect taxes, but these indirect taxes are not
received by the factors of production as incomes. Additionally where producers are subsidized
by government, the factors of production receive rewards in excess of the payments made for
goods and services in the market. Therefore from national income figures at market prices
indirect taxes must be subtracted but subsidies must be added to obtain the national income
figures at factor cost.
NYMP – Indirect taxes + Subsidies = NYFC
Or NYFC + Indirect taxes – Subsidies = NYMP
Examples
a) Convert GDPMP to GDPFC
GDPMP – Indirect taxes + Subsidies = GDPFC
b) Adjust GDPMP to NNPFC
GDPMP + Net income from abroad - Depreciation – Indirect taxes + subsidies = NNPFC
c) Convert NNPFC to GNPMP
NNPFC + Depreciation + Indirect taxes – Subsidies = GNPMP
SUMMARY OF ADJUSTMENTS
ADJUSTMENT PROCEDURE
1 Gross to Net Subtract depreciation
2 Net to Gross Add depreciation
3 Domestic to National Add net income from abroad
4 National to Domestic Subtract net income from abroad
5 Market prices to Factor cost Subtract indirect taxes and add subsidies
6 Factor cost to Market prices Add indirect taxes and subtract subsidies
EXERCISE
1) Given GNPFC what adjustments should be made to obtain NNPMP
2) Given that the GDPFC = $1200millions, GNPMP = $1500millions, Depreciation = $20
millions, indirect taxes = $5millions, subsidies = $2millions
Calculate the net income from abroad
3) Study the table below and answer the questions that follow
ITEM VALUE (Billion shilling)
GDPMP 160,000
Net income from abroad 150,000
Capital consumption 800
Negative taxes 50,000

(iii) The GNPMP
(iv) The NNPFC
5) DISCRETIONARY INCOME
This is the amount of income that individuals are left with for saving or spending after paying
taxes and covering all the essential expenses. Therefore discretionary income is for saving and
catering for nonessential expenses like investments, entertainment, home improvements, debt
repayment, luxuries e.t.c
©Economics department 5
6) SOCIAL INCOME
This is the total value of all the benefits and services that an individual receives which are
beyond the monetary income. They include the social capital, public goods and services, social
benefits like insurance, social support networks e.t.c
7) NOMINAL INCOME
This is one’s income expressed in monetary terms.
8) REAL INCOME
This is income expressed in terms of goods and services it can buy.
OR: It is the purchasing power of nominal/money income.
Determinants of Real Income:
Price levels/Rate of inflation.
Amount/quantity of goods and services available.
The size of nominal income.
Level of taxation/size of disposable income.
Level of money supply/ amount of money in circulation.
Size of the monetary sector/ subsistence sector.
The land tenure system; A good land tenure system makes it easy to acquire land and
set up economic activities which leads to high volume of goods and services produced
thus high level of national income, while a poor land tenure system makes it hard to
acquire land which limits investment leading low level of output of goods and services
and thus low level of national income.
Level of existing capital stock; Adequate liquid capital enable producers to acquire
sufficient factor inputs which leads to high production of goods and services and thus
high level of national income, on the other hand limited capital makes it hard for
©Economics department 6
producers to acquire sufficient factor inputs which limits production leading to low level
of national income..
The techniques of production. Modern techniques of production lead to a high level of
efficiency in production which leads to a high volume of goods and services produced
hence a high level of national income but poor techniques of production lead to
inefficiency in production which leads to low output produced and thus low level of
national income
The political atmosphere/political climate: Political stability encourages production
because producers settle down to carry out production without the fear of losing their
lives and property and thus high levels of national income, while political instability
discourages production because producers are scared of losing their lives and property
which leads to a low level of national income
The market size. A large market size leads to a high level of sales and profits which
leads to high production of goods and services and therefore a high level of national
income but a small market size leads to a low level of sales and low profits or losses
which discourages production and thus leads to a low level of national income
The level of monetization of the economy/size of subsistence sector; A large
subsistence sector/low level of monetization limits production because most people
produce on a small scale for their own consumption thus low level of national income,
while a small subsistence sector/high level of monetization encourages production
because most people produce on a large scale which leads to high output and thus high
levels of national income.
The entrepreneurial ability/level of entrepreneurship; High level of entrepreneurial
ability leads to better organization of the factors of production which leads to high level
of production and thus high level of national income, while low level of entrepreneurial
skills leads to poor organization of the factors of production among producers which
leads to low levels of production and thus low levels of national income. .
The level of infrastructural development; High level of infrastructural development
encourages production because it lowers the costs of production thus high levels of
national income, while underdeveloped infrastructure discourages production because it
leads to high costs of production thus low levels of national income.
The price levels/Rate of inflation. Low rate of inflation encourages production due to
the low cost of acquiring factor inputs thus high level of national income, while high rate
of inflation discourages production because of high cost of acquiring factor inputs thus
low levels of national income.
The population growth rate; High population growth rate leads to high dependence
burden which limits savings leading to low levels of investment and output, therefore low
levels of national income, while low population growth rate leads to a low dependence
burden which encourages savings thus high levels of investment and output leading to
high levels of national income.
©Economics department 7
Level of savings; High level of savings leads to increased investment because it leads to
accumulation of more funds for the investors to purchase inputs for investment which
increases production of goods and services thus high levels of national income, while low
levels of savings leads to limited accumulation of funds for investment which limits
production and thus low levels of national income.
The level of accountability; High level of accountability attracts more investors because
they easily acquire licences without incurring costs of paying bribes to government
officials which encourages economic activities , leads to increased production thus high
levels of national income, while low levels of accountability discourages investors
because they find it hard to acquire licences and have to incur high costs of paying bribes
to the government officials which limits setting up economic activities leading to low
production and thus low levels of national income
©Economics department 8
Low levels of existing capital stock/inadequate capital
Low levels of entrepreneurial abilities/skills
High population growth rate
The existence of a large subsistence sector/low levels of monetization of the economy
Low levels of education and training/low levels of skills
Limited investment incentives
Cultural rigidities/High degree of conservatism
The poor land tenure system
Low levels of accountability/High levels of corruption
Negative attitude towards work
Increase the level of exploitation of natural resources. This will increase the supply of raw
materials for use in production and hence increase the level of output of goods and services
thus increase the level of national income.
Improve the state of technology (Technology development/transfer). This will increase
the level of efficiency in production of goods and services thus increase the level of national
income.
Equip labour with skills. This can increase the level of efficiency in production and thus
increase the volume of goods and services produced and hence increase the level of national
income.
©Economics department 9
Develop economic infrastructure This will reduce production costs which increase the level
of investments and production of goods and services and thus increase the level of national
income.
Provide investment incentives. This will reduce costs of production which will lead to
increase in the level of investments and volume of goods produced hence increase level of
national income.
Modernize the agricultural sector. This will facilitate production throughout the year in
addition to use of better technology which will increase output produced in the agricultural
sector and thus increase the level of national income
Provide credit facilities to producers. This will enable the producers purchase enough
factor inputs to carry out investments which will increase the volume of goods and services
produced hence increase the level of national income.
Encourage saving. This will facilitate accumulation of adequate funds for purchasing inputs
for investment and thus increase output produced and national income
Expand markets. This will increase the level of sales and profits which will encourage more
investments and therefore increase output produced and thus increase national income
Ensure political stability. This will increase security for lives and property of the
producers/investors and therefore increase investments and output of goods and services
Control population growth rate. This will reduce the dependency burden, encourage saving
and investment which will increase output and national income
Encourage economic diversification. This will increase the range of investments and
economic activities in the different sectors of the economy which will increase output and
national income
Carry out further privatization of public enterprises. This is intended to promote
efficiency, increase volume of goods and services hence increase the level of national
income.
Improve entrepreneurial skills. This will lead to better organization of the factors of
production which will increase output and national income
Carry out further liberalization of trade. This will reduce production costs which will
encourage more investments and hence increase output and national income

The output approach/Value added method
This involves adding up the monetary value of all final goods and services arising from the
productive activities of the country in a given year
Or it involves adding up the value added to output at each stage of production in the country in a
year
(N.B Value added = Value of output – Value of inputs)
Challenges of using the output approach/ value added method
Problem of double counting/difficulty of distinguishing between final and intermediate
output
Inadequate information
Difficulty of valuing subsistence output
Difficulty of determining the boundary of production
Problem of valuing inventories and work in progress
Inadequate skilled labour
Inadequate facilities
Price changes/fluctuations
Difficulty of valuing services provided by government
Question 1 (a) How is national income estimated in Uganda? (04 mark)
(b) Explain the challenges faced in estimation of national income in Uganda
(16 marks)
2(a) How is the output approach used in estimation of national income? (04 marks)
(b)Which approach is most appropriate for estimation of national income in Uganda
and why?
Inadequate statistical information/data. People have many sources of income that are
not disclosed and, and many expenditures or output produced that is nor recorded
anywhere and therefore left out during compilation of national income which leads to
underestimation of the national income figures
Double counting. This involves counting some activities/products/items more than once
which arises due to failure to differentiate between final and intermediate products. It
leads to over estimation of national income
Difficulty of determining the boundary of production. It is hard to identify activities that
are productive and thus consider them in estimation of national income and then those
that are non- productive so as to exclude them during estimation of national income
Difficulty of valuing government output/services. These are not paid for while others are
highly subsidized making it difficult to get estimate their value in monetary terms
Difficulty of valuing subsistence output/non-marketed output. This output does not go
through the market and therefore does not have market prices attached making it hard to
value it in monetary terms
©Economics department 12
Challenges of valuing unpaid for services. These include the services of house wives,
services of charitable organizations e.t.c which are not paid for yet happen to be
productive and hence the difficulty of valuing them in monetary terms
Difficulty of determining the net income from abroad. Some of the country`s nationals
get incomes from abroad that are not very clear and through unofficial channels making it
difficult to identify them and include them in the country`s national income figures
Problem of inventories and work in progress(Difficulty of timing production). Some
goods are produced in one year but not sold within that year (inventories) making it hard
to attach a monetary value to them and to determine the time period to which to attach
them. Production of some goods extends over several years and therefore happen to be
incomplete at the end of the accounting period (Work in progress)
Price changes. Price fluctuations with the accounting period results into a challenge of
determining the appropriate prices to attach to the goods and services produced in order
come up with the actual monetary value of the output produced. As prices increase the
nominal national income figure increases even without an increase in the real output
Difficulty of determining the value of depreciation. The wear and tear of
machines/capital assets during the process of production is difficult to determine and
express in monetary terms
Inadequate facilities. These include the computers and other gadgets used for collecting
and storing information. This results into loss of some of the information collected.
Limited skills of the statisticians. This results into inefficiency during the process of
collecting and processing the information which results into inaccurate figures of national
income Problem of illegal activities. Incomes from illegal activities are not supposed to
be included in estimation of national income however its sometimes difficult to identify
such incomes so as to exclude them
Problem of errors of omission and commission. Some activities /output or incomes are
left out where as they should have been included while others are considered where as
they should have been excluded which results into underestimation or over estimation of
the country`s national income respectively
Problem of illegal activities. Incomes from illegal activities are not supposed to be
included in estimation of national income however its sometimes difficult to identify such
incomes so as to exclude them
Conceptual problems are the problems related to understanding and interpretation of the
concept of national income. They basically involve determining what to include and what
to exclude in estimation of national income and the appropriate valuation methods. In
some countries some activities are considered in estimation of national income while in
©Economics department 13
other countries they are left out due to lack of a uniform/universal interpretation of the
concept
The conceptual problems include the following
Problem of determining the boundary of production
Problem of unpaid for services
Difficulty of distinguishing between final and intermediate products
Problem of inventories and work in progress/timing production
Problem of determining the legal and illegal activities
Problem determining the transfer payments and the earned incomes
Limited skilled manpower
Statistical challenges are problems related to collection, compilation and analysis of
information/data,.
The statistical problems include
Limited statistical information
Difficulty of determining the net income from abroad
Difficulty of determining the value of depreciation
Problem of double counting
Problem of price changes
Difficulty of valuing subsistence output
Problem of valuing inventories and work in progress
Difficulty of valuing government services
Problem of valuing unpaid for services

IDENTICAL/SAME RESULTS OF THE THREE APPROACHES OF
ESTIMATION OF NATIONAL INCOME
The income approach, expenditure approach and the output approach are
identical/equivalent because in principle they are expected to give /yield the same figure
of national income (O ≡ Y ≡ E)
This because of the following
(i) The monetary value of the output produced by the firms is equal to the
expenditure by households on the final goods and services in the market, thus the
output approach is equivalent/identical to the expenditure approach (O ≡ E ¿
(ii) The monetary value of the output produced by the firms in form of receipts from
the sale of output is equal to their expenditure on payments to the factors of
production , thus the output approach is equivalent to the income approach
(O ≡Y ¿
(iii) The factor income payments received by households are spent on purchasing final
goods and services in the market, therefore the income approach is equal to the
expenditure approach (Y ≡ E ¿
©Economics department 14
Identity of the three approaches is illustrated by the circular flow of income

(ii) The monetary value of the goods and services supplied by the business sector
(arrow 2) is equal to the payments made for the goods and services by the house
holds(arrow 4), thus O≡E
(iii) Receipts from the sale of goods and services got by the firms(arrow 4) are equal to
the payments made for factor services(arrow 3), thus O ≡Y

In a closed economy
Aggregate demand and aggregate supply
Aggregate demand is the total demand for goods and services in an economy in a given period
of time or the total planned expenditure on goods and services in an economy in a given period
of time. In an open economy Aggregate demand = C + I + G +( X – M), therefore the
components of aggregate demand are;
(i) Consumption expenditure (C)
(ii) Investment expenditure (I)
(iii) Government expenditure (G)
(iv) Net expenditure on exports (X – M)
However in a closed economy Aggregate demand = C + I + G
The determinants of aggregate demand include
The general price level
Income level
Population size
Government policy of taxation/subsidization
Availability of credit
The existing stock of capital
The level of money supply
The exchange rate
Question (a) Account for the negative slope of the aggregate demand curve
(b) Explain the conditions that may lead to a change in an aggregate demand in an
economy
Aggregate supply is the total supply of goods and services in an economy in a given period of
time. The determinants of aggregate supply include;(similar to determinants of total
output/national income)
The level of aggregate demand/size of the market
The general price level/rate of inflation
Government policy on production/investment
Political climate
The techniques of production
Level of development of infrastructure
The land tenure system
Level of entrepreneurial skills/number of producers
Availability of factor inputs e.g capital
Level of labour skills
Level of accountability
The costs of production
Question ; (a) Distinguish between market supply and aggregate supply
(b) Examine the factors that determine the level of aggregate supply in an economy
©Economics department 18
The inflationary gap/negative output gap
This is where aggregate demand is greater than aggregate supply at the full employment level of
national income /resources. In this case there is excessive aggregate demand for goods and
services over the aggregate supply
©Economics department 19
Leads to increase in demand for factor inputs
Leads to an increase in output/economic growth
Leads to an increase in tax revenue
Policy measures that can be adopted to close/reduce an inflationary gap
(Basically those that reduce aggregate demand)
Increase direct taxes. This can reduce the disposable income and aggregate demand and
hence reduce the inflationary gap
Reduce government expenditure. This will reduce money supply and hence reduce
aggregate demand
Adopt a restrictive monetary policy. This will reduce the amount of money in circulation
and hence reduce aggregate demand
Adopt wage control measure (such as the wage freeze and wage restraint). This will
control aggregate demand in the economy
Encourage importation. This will increase the supply of goods and services in the
economy
Discourage exportation. This will avail more goods for consumption in the domestic
market
Adopt maximum price legislation. This will prevent further increases in the prices and
thus control the gap
©Economics department 20
Illustration of a deflationary gap
Factors that may lead to deflationary gap(Basically those that reduce aggregate demand)
Adoption of a restrictive monetary policy
Increase in direct taxes
Decrease in government expenditure
Increase in importation of goods and services
Decrease in exportation of goods and services
Decrease in wages
©Economics department 21
Increase government expenditure. This will increase money supply and eventually
increase aggregate demand
Reduce direct taxes. This will increase the people`s disposable income and hence
increase aggregate demand
Encourage exportation. This will dispose off the excess supply of goods and services by
taking them to other countries
Discourage importation. This will reduce the excess supply of goods and services
coming from other countries
Increase wages. This will increase the people`s purchasing power and hence increase
aggregate demand

(i) an inflationary gap,
(ii) a deflationary gap,
In an economy. (16 marks)
CONSUMPTION
Consumption is the proportion of income spent by households on final goods and services that
yield utility /satisfaction of human wants
Or a process of utilizing/using final goods and services to get satisfaction/utility
The level of consumption is related to the level of national income in a way that a high level of
consumption leads to a high level of investment which leads to a high level of output hence a
high level of national income and a low level of consumption discourages investment which
leads to low output produced and thus a low level of national income
©Economics department 22
Concepts related to consumption
Consumption expenditure. This is the amount of money spent on final goods and
services to provide utility/satisfy human wants(either individually or collectively)
Marginal propensity to consume. This the proportion of the additional income which is
Change∈consumption
spent on consumption, MPC =
Change∈income
Average propensity to consume. This is the proportion of the total income which is
Total consumption
spent on consumption. APC =
Total income
Autonomous consumption. This is consumption which is independent of the level of
income
Induced consumption. This is consumption which depends on the level of income
Consumption function. This is a statement indicating the level of consumption and the
level of income in an economy
Determinants of consumption/consumption expenditure
Level of income. High level of income leads to a high level of
consumption/consumption expenditure because of the high purchasing power but a low
level of income leads a low level of consumption due to the low purchasing power
Level of taxation/subsidization. A high level of taxation(or low subsidization) leads to
low levels of consumption because of the low disposable income while low levels of
taxation lead to high levels of consumption because of the high disposable income
The population size. A large population size leads to a high level of consumption
because of the large number of people that buy the consumer goods but a small
population leads to low levels of consumption because of the small number of people that
buy the consumer goods
The price level/rate of inflation. A high price level leads to low levels of consumption
because goods and services are very expensive and un affordable for most of the
consumers but a low price level leads to high levels of consumption
Availability of goods and services. Adequate supply of goods and services leads to high
levels of consumption because the goods and services turn out to be cheap and affordable
but inadequate supply of goods and services leads to low levels of consumption
The level of monetization/size of the subsistence sector. A large subsistence sector/low
level of monetization leads to high levels of consumption because of the high output and
incomes but a low level of monetization leads to low levels of consumption
Level of speculation/expectations of future prices changes. Expectation of future
increase in the prices leads to high levels of consumption so as to avoid buying the goods
expensively while expectation of future decrease in prices leads to low levels of
consumption as many people wait to buy the goods in future when prices have reduced
The marginal propensity to consume /save. A high MPC leads to high levels of
consumption because as incomes increase a bigger proportion of income is spent on
consumption but a low MPC leads to low levels of consumption because as incomes
increase a small proportion of income is spent on consumption
Availability of credit. Availability of enough credit leads to high levels of consumption
because people without cash able to borrow money and buy the consumer goods while
limited availability of credit leads to low levels of consumption because people without
enough cash find it hard to borrow money for buying the consumer goods
©Economics department 23
Seasonal factors. Favourable seasonal factors leads to high consumption because the
goods and services are needed for use in that period/season but unfavourable seasonal
factors lead to low levels of consumption
The rate of interest. A low rate of interest on savings in financial institutions leads to a
high level of consumption because most people are discouraged from saving by the low
benefits but a high rate of interest on savings leads to low levels of consumption because
people are encouraged by the high benefits to save more and more
Question1 (a) Distinguish between marginal propensity to consume and average
Propensity to consume (04 marks)
(b) Account for the low levels of consumption in an economy (16 marks)
Question 2(a) Explain the factors that influence consumption expenditure in Uganda
(10marks)
(b) What policy measures can the government adopt to minimize
Consumption expenditure in Uganda (10 marks)
Saving/savings
Saving(s) is the proportion of the disposable income not spent on current consumption but kept
aside for future use.
Or it is a process of foregoing current consumption in order to raise funds/money for future use.
The types of savings include; personal savings, corporate savings, forced/compulsory savings,
Government savings
©Economics department 24
Level of taxation/subsidization. A high level of taxation leads to a low level of saving
because it results into a a low disposable income left for spending on consumption and
saving but a a low level of taxation leads to a high level of saving
The rate of inflation/price level. A high rate of inflation leads to a low level of saving
due to the high expenditure on consumption and a low rate of inflation leads to a high
level of savings because of the low expenditure on consumption
The level of development of the (financial)infrastructure. A high level of
development of the financial infrastructure leads to a high level of savings because
people find it easy to open up saving accounts but a low level of development of the
financial infrastructure leads to a low level of savings because it becomes difficult to
open up saving accounts
The population growth rate. A high population growth rate leads to a high dependency
burden which leads to high expenditure on consumption which leads to a low level of
savings while a low population growth rate leads to low expenditure on consumption
hence a high level of savings
The rate of interest on savings. A high rate of interest on savings leads to a low level of
savings because of the low returns on savings in the banks but a high rate of interest on
savings leads to a high level of savings
The level of liquidity preference. High liquidity preference leads to a low level of
savings because people prefer to have cash with them to saving in financial institutions
which prompts them to spend more and more, but low liquidity preference leads to a
high level of saving because people prefer keep their wealth in form of savings in
financial institutions
Level of monetization/commercialization. A high level of monetization leads to a high
level of savings because of the high level of incomes earned as many people produce for
sale in the market but a low level of monetization/large subsistence sector leads to low
savings because most people produce on a small scale for personal/family consumption
which results into low incomes
Level of accountability in the( financial sector). A high level of accountability in the
financial sector leads to a high level of savings because people are confident that their
savings in the financial institutions won’t be misappropriated but a low level of
accountability leads to a low level of savings
The marginal propensity to save. A high MPS leads to a high level of saving because
as people`s income increase a bigger proportion of their incomes is saved but a low
MPS leads to a low level of saving
The government policy on saving. Afavourable government policy on saving leads to
high level saving because saving is made to be compulsory but unfavourable government
policy on saving leads to a low level of saving because saving becomes voluntary
The time preference/Peoples spending habits. Positive time preference leads to a low
level of saving because people prefer to spend a bigger proportion of their incomes on
consumption in the current period but negative time preference leads to a high level of
saving because people prefer to spend on consumption in future periods
The existing stock of wealth. A large stock of wealth leads to a high level of saving
while a low stock of wealth leads to low level of savings

Increase the level of monetization
Encourage compulsory savings
Increase the interest rate on savings
Promote accountability in the financial sector
Reduce taxes on incomes/subsidize the consumers
Sensitize the population about the importance of saving
Control the population growth rate
Ensure even distribution of financial institutions in the country
INVESTMENT
Investment is the process of devoting part of person`s or nation`s income to production of capital
goods. An investment is a business activity established or asset purchased with an aim of
generating income. Investment expenditure is the amount of money devoted to
creation/increasing the existing stock of capital
Types of investment
Induced investment. This is investment that varies with the level of income.
Autonomous investment. This is investment which is independent of/does not vary with
the level of income.
Gross investment. This is the total amount of investment undertaken (which includes
that for increasing the capital stock and that for replacing worn out capital) in a given
period of time. It includes net investment and replacement investment.
Net investment. This is the expenditure on creation of new capital goods. Net investment
increases on the existing stock of capital goods
Replacement investment. This is the expenditure on repair and replacement of worn out
capital.
N.B ; Gross investment = Net investment + Replacement investment
Real /physical investments. These are investments in tangible or physical assets
Financial investments. These are investments or expenditure on purchase of financial
securities

investment on the other hand limited skills of workers leads to low level of efficiency in
production which leads to low levels of investment
The land tenure system; A good land tenure system makes it easy to acquire land and
set up economic activities which leads to a high level of investment while a poor land
tenure system makes it hard to acquire land which limits investment
Level of existing capital stock; Adequate liquid capital enable producers to acquire
sufficient factor inputs which encourages investment on the other hand limited capital

fear of losing their lives and property which leads to a low level of investment
The level of monetization of the economy/size of subsistence sector; A large
subsistence sector/low level of monetization limits investment because most people
produce on a small scale for their own consumption while a small subsistence sector/high
level of monetization encourages investment because most people produce on a large
scale for the market which leads to high levels of investment
The level of entrepreneurial ability High level of entrepreneurial ability leads to better
organization of the factors of production which leads to high levels of investment while a
low level of entrepreneurial skills leads to poor organization of the factors of production
among producers which leads to low levels of investment.
The level of infrastructural development; High level of infrastructural development
encourages investment because it lowers the costs of production while underdeveloped
infrastructure discourages investment because it leads to high costs of production
Rate of inflation. Low rate of inflation encourages investment due to the low cost of
acquiring factor inputs while high rate of inflation discourages investment because of
high cost of acquiring factor inputs
The population growth rate; High population growth rate leads to high dependence
burden which limits savings leading to low levels of investment while low population
growth rate leads to a low dependence burden which encourages savings thus high levels
of investment
Level of savings; High level of savings leads to increased investment because it leads to
accumulation of more funds for the investors to purchase inputs for investment while low
levels of savings leads to limited accumulation of funds for investment hence low levels
of investment
The level of accountability; High level of accountability attracts more investors because
they easily acquire licences without incurring costs of paying bribes to government
officials which leads to high levels of investment, while low levels of accountability
discourages investors because they find it hard to acquire licences and have to incur high
costs of paying bribes to the government officials which leads to low levels of
investment
The degree or level of conservatism; High degree of conservatism limits investment
because many people stick to the traditional methods of production which are low
©Economics department 27
yielding while a low level of conservatism encourages investment because many people
embrace modern methods of production which are high yielding .
The government policy on investment. A favourable government policy on investment
e.g in form of tax holidays, subsidies reduces the cost of production and thus leads to
high levels of investment on the other hand an unfavourable government policy on
investment leads to high costs of production which leads to low investment
The marginal efficiency of capital. A high marginal efficiency of capital leads to a high
level of investment because of the high expected returns on an additional unit of capital
employed but a low marginal efficiency of capital leads to low levels of investment
because of the low expected returns on an additional unit of capital employed
N.B Marginal efficiency of capital is the expected rate of return on an additional
unit of capital employed. Its determinants are ; The price level, level of taxation, level of
output, size of the market, rate of depreciation of capital, rate of interest

Provide credit facilities to producers. This will enable the producers purchase enough
factor inputs to carry out investments and hence increase investment
Encourage saving. This will facilitate accumulation of adequate funds for purchasing
inputs for investment and thus increase investment
Expand markets. This will increase the level of sales and profits which will encourage
more investments
Ensure political stability. This will increase security for lives and property of the
producers/investors and therefore increase investments
Control population growth rate. This will reduce the dependency burden, encourage
saving and increase investment
Encourage economic diversification. This will increase the range of economic activities
in the different sectors of the economy which will increase investment
Carry out further privatization of public enterprises. This is intended to promote
efficiency and increase investment
Improve entrepreneurial skills. This will lead to better organization of the factors of
production which will increase investment
Carry out further liberalization of trade. This will reduce production costs which will
encourage more investment

Operation/Working of the investment multiplier
Question; Given that the MPC = 80% and the increase in investment expenditure is
shillings 1000 millions, how does the investment multiplier operate in the
economy?
An increase in investment expenditure leads to increased production and income in
period one.
The increase in income in period one generate increase in consumption expenditure and
saving depending on the MPC and MPS
The increase in consumption expenditure in round/period one creates an increase in
production and income of the same amount in period two
The increase in income in period two creates farther increases in consumption
expenditure and savings
The process continues till no further increases in income and expenditure are possible
©Economics department 34
to a low level of investment, low output produced and thus limited operation of the
investment multiplier/small investment multiplier
Level of skills of workers/Availability of skilled labour force; High level of skills of
workers leads to high level of efficiency in production which leads to a high level of
investment and production hence effective operation of the investment multiplier and on
the other hand limited skills of workers leads to low level of efficiency in production
which leads to low levels of investment, low output produced hence limited operation of
the investment multiplier
The land tenure system. A good land tenure system makes it easy to acquire land and
set up economic activities which leads to a high level of investment which increases
output and hence encourages operation of the investment multiplier while a poor land
tenure system makes it hard to acquire land which limits investment, limits output and
thus limits operation of the investment multiplier
Level of existing capital stock; Adequate liquid capital enable producers to acquire
sufficient factor inputs which encourages investment, increases output and therefore
encourages operation of the multiplier and on the other hand limited capital makes it
hard for producers to acquire sufficient factor inputs which limits investment, limits
output and hence limits operation of the investment multiplier
The techniques of production. Modern techniques of production lead to a high level of
efficiency in production which leads to high levels of investment, increases output and
hence encourages operation of the investment multiplier but poor techniques of
production lead to inefficiency in production which leads to low investment and low
output thus limited operation of the investment multiplier
The political atmosphere/political climate: Political stability encourages production
because producers settle down to carry out production without the fear of losing their
lives which leads to high levels of investment and output thus effective operation of the
multiplier while political instability results into the fear of losing their lives and property
which leads to a low level of investment , low output and thus limited operation of the
multiplier
The level of entrepreneurial ability. High level of entrepreneurial ability leads to
better organization of the factors of production which leads to high levels of investment
and output produced hence effective operation of the investment multiplier while a low
level of entrepreneurial skills leads to poor organization of the factors of production
among producers which leads to low levels of investment, low output and thus limited
operation of the multiplier
The level of infrastructural development; High level of infrastructural development
encourages investment because it lowers the costs of production which increases output
and hence effective operation of the multiplier while underdeveloped infrastructure
discourages investment because it leads to high costs of production which limits output
and thus limits operation of the multiplier
Rate of inflation. Low rate of inflation encourages investment due to the low cost of
acquiring factor inputs which increases output and therefore encourages operation of the
investment multiplier while high rate of inflation discourages investment because of high
cost of acquiring factor inputs which limits output and hence limits operation of the
multiplier
©Economics department 35
The population growth rate; High population growth rate leads to high dependence
burden which limits savings leading to low levels of investment, low output which limits
operation of the investment multiplier while low population growth rate leads to a low
dependence burden which encourages savings thus high levels of investment that
increase output and therefore encourage operation of the multiplier
Level of savings; High level of savings leads to increased investment because it leads to
accumulation of more funds for the investors to purchase inputs for investment which
increases output and therefore encourages operation of the investment multiplier while
low levels of savings leads to limited accumulation of funds for investment hence low
levels of investment, low output and limits operation of the investment multiplier
The level of accountability; High level of accountability attracts more investors because
they easily acquire licences without incurring high costs of paying bribes to government
officials which leads to high levels of investment and output which encourages effective
operation of the investment multiplier while low levels of accountability discourages
investors because they find it hard to acquire licences and have to incur high costs of
paying bribes to the government officials which leads to low levels of investment and
low output and thus limits operation of the multiplier
The government policy on investment. A favourable government policy on investment
e.g in form of tax holidays, subsidies reduces the cost of production and thus leads to
high levels of investment and high output produced hence effective operation of the
investment multiplier on the other hand an unfavourable government policy on
investment leads to high costs of production which leads to low investment and low
output produced thus limited operation of the multiplier
The marginal propensity to import. A high marginal propensity to import results into
increased importation of better quality goods which leads to low sales and low profits
made by the local firms, discourages investment and production and thus limits effective
operation of the investment multiplier but a low marginal propensity to import results a
high level of sales and profits for the local firms which encourages investment and
production thus encourages operation of the investment multiplier
The level of liquidity preference. High liquidity preference leads to low savings in the
financial institutions because people prefer to keep their wealth in cash form and thus
spend most of it, this leads to low investment and low output and thus limits effective
operation of the investment multiplier but low liquidity preference leads to a high level
of savings and investment which increases output and thus encourages operation of the
investment multiplier

Per capita income is the average income of the population in a country in a given period of time.
It is calculated by dividing the country`s national income/GDP by the population size
Uses of income per capita
Used to measure the standard of living/people`s welfare
Used to compare the standard of living in a country over time
Used to compare the standard of living between countries
Used to measure rate of economic growth/performance
Used to for economic analysis and planning
Used to determine the level of resource exploitation/utilization
Used when soliciting for foreign aid
Question (a) Why is it necessary to calculate income per capita in developing countries?
(b) Account for the low per capita income figures in developing countries
(Due to factors that lead to low levels of national income )
Standard of living
This is the socio-economic welfare of an individual or society as measured by the basket of
goods and services enjoyed. It refers to the conditions of life/quality of lives in which people live
as determined by the quantity and quality of goods and services that people are able to enjoy
Determinants of the standard of living
Level of income
High income levels lead to high standard of living since people have enough income to afford
more goods and services thereby making life more comfortable and low income levels limits the
amount and quality of goods and services consumed thereby leading to low standard of living.
Level of employment/ unemployment
High levels of employment lead to high income levels thereby leading to high standard of living
in an economy because many people are able to afford enough goods and services while high
levels of unemployment lead to low income levels and low standard of living.
Degree of political freedom.
©Economics department 38
A high degree of freedom leads to a high standard of living because people have freedom of
speech, movement, and association but a low degree of freedom leads to low standards of living
because of lack of freedom of association and speech
Political atmosphere/ climate.
Political stability enables individuals to enjoy comfortable lives because they have peace of mind
and security for lives and property hence high standard of living. On the other hand, political
instability leads to low standard of living because of lack of security for lives and property
The general price level in an economy/ rate of inflation.
A high price level/rate of inflation leads to a low standard of living because goods and services
are expensive and unaffordable for most people but a low price level leads to a high standard of
living because the goods and services are cheap and affordable for most people
Nature of goods produced ( capital goods or consumer goods)
Production of consumer goods at the expense of capital goods leads to a high standard of living
because such consumer goods provide direct satisfaction to the users but production of capital
goods at the expense of consumer goods leads to a low standard of living because the capital
goods don’t provide direct satisfaction
The quality of goods produced/consumed
Production and consumption of poor quality goods and services leads to a low standard of living
because such goods negatively affect people`s health and lives but better quality goods and
services lead to a high standard of living because such goods improve people`s health and lives
Level of social costs/pollution.
High levels of pollution create a bad environment that negatively affects people`s health and
lives which lowers the welfare of people while low levels of pollution create a good environment
which improves people`s health and lives thus a high standard of living
Availability of time for leisure/Number of hours worked for.
Lack of leisure leads to a low standard of living because people are over worked and don’t have
enough time for resting and relaxing but enjoyment of enough leisure leads to a high standard of
living because people have enough time for resting
Nature of income distribution.
High levels of income inequality lead to a low standard of living because most of the people are
low income earners who cannot afford to purchase and enjoy enough goods and services but
even distribution of income leads to a high standard of living because most of the people have
enough incomes that enable them purchase and enjoy enough goods and services cons
The nature/pattern of government expenditure
High government expenditure on non- productive activities e.g luxuries for government officials
and expensive ceremonies leads to a low standard of living because it limits provision of
essential goods and services for the people but high government expenditure on provision of
social services for the people leads to a high standard of living
The working conditions/ occupational hazards.
Favourable working conditions lead to a high standard of living because workers are provided
with enough welfare facilities and occupational hazards at the place of work are reduced but poor
working conditions lead to a low standard of living because of lack of welfare facilities and the
high level of occupational hazards
Level of education and skills.
A high level of education and skills leads to a high standard of living because many people are
high efficient in production which leads to high output and incomes while low levels of
©Economics department 39
education and skills lead to inefficiency in production which leads to low output and low
incomes earned and thus limited enjoyment of goods and services
©Economics department 40
Measures that can be adopted to improve people`s standards of living
Develop labour skills/reform the education system
Provide affordable credit
Improve infrastructure
Ensure political stability
Control the population growth rate
Encourage subsidization of the low income earners
Encourage environmental protection to reduce pollution
Fight conservatism
Reform the land tenure system
Develop entrepreneurship skills
Liberalize trade
Control inflation/ensure price stability
Adopt progressive taxation
Increase political freedom
Encourage production/consumption of quality goods and services
Increase government expenditure on provision of social services
©Economics department 41
High government expenditure on non- productive activities results into a low standard of living
despite per capita income being high because such expenditures don’t improve people`s welfare
but high government expenditure on provision of social services leads to a high standard of
living even when per capita income is low because such expenditures improve people`s welfare
It does not take into account the nature of goods produced.
Per capita income figures may be high but when the economy is producing large volumes of
capital goods at the expense of consumer goods yet capital goods do not directly improve
peoples’ welfare which instead leads to a low standard of living but production of more of
consumer goods leads to a high standard of living despite per capita income being low
It does not consider the amount of leisure foregone./number of hours worked for
Per capita income figures may be high but when high output levels are as a result of over
working labour which leads to a low standard of living because people have no time for resting
but if they enjoy enough leisure the standard of living will be high despite income per capita
being low
It does not take into account the working conditions of the people.
Individuals working in very poor conditions are exposed to occupational hazards which are
likely to reduce their welfare despite the high per capita income figure in the country but good
working conditions lead to a high standard of living even with per capita income being low
©Economics department 42
Over estimation of the national income and under estimation of the population results into an
over estimated figure for the income per capita implying that the standard of living tends to be
low despite a high income per capita
It does not consider the subsistence output.
Per capita income may be low due to the presence of a large subsistence sector where people do
not earn incomes but produce their own goods and services for consumption which improves
their welfare
It ignores the level of taxation in the country
A high level of taxation leads to a low standard of living despite a high per capita income
because people are left with a low disposable income and therefore unable to enjoy enough
goods and services but low taxation leads to a high standard of living despite income per capita
being low
©Economics department 43
The per capita income may be high in a country where people experience a lot of occupational
hazards which negatively affect their welfare and yet in a country where there is low per capita
income people may not be suffering from such occupational hazards hence enjoying better
economic welfare.
It does not consider differences in the level/size of subsistence sector between
countries .
The per capita income may be low in a country where there is a large subsistence sector or non-
monetary output which greatly contributes to peoples welfare yet in another country with a small
subsistence sector but with a higher per capita income the standard of living is lower
It does not consider the differences in the general price levels/rate of inflation between
countries.
Per capita income figure may be high in a country where there is a high rate of inflation which
implies high cost of living leading to low economic welfare and yet in another country where per
capita income is lower, there may be low rate of inflation or price stability which implies low
cost of living and hence better economic welfare.
It does not consider the differences in the political climate between countries.
Per capita income may be high in a country where there are wars which negatively affect
people’s welfare because of the constant fear of loss of lives and property yet per capita income
may be low in a country where there is political stability and the people in such a country are
enjoying high standard of living despite the low per capita income.
It does not consider the differences in the quality of goods and services produced
between countries;
Per capita income may be high in a country where the commodities produced are of low quality
which negatively affects their health and lowers their standards of living and yet per capita
income may be low in another country where goods produced are of a high quality which
implies better standards of living of such people.
It does not consider the differences in the degree of accuracy of statistical data
between countries i.e. in terms of population size and national income figures.
The per capita income may be high in a country when the statistical data was inaccurate
especially concerning the population size and yet in another country where per capita income is
low, they may be having accurate statistical data, this makes the standard of living lower in a
country with a higher per capita income
It does not take into account the differences in social costs between countries such as
pollution.
The per capita income may be high in a country where there are high problems of social costs
especially pollution which negatively affects people`s health. this lower people’s standards of
living in such a country despite the high per capita income. Yet in another country with a low per
capita income such social costs may be minimal implying better standards of living of the people
in such a country.
It does not take into account the differences in requirements for confortable living
between countries. Countries experiencing winter need substantial conditioning of houses and
©Economics department 44
warm clothing like winter cloth and therefore those facilities must be produced. In tropical
Africa for instance, expenses on warm heating and warm clothing may not be essential and
therefore no need for producing such commodities. In a cold country, per capita income figures
may be high because of heating expenses; however this does not mean that people in such
countries are better off, than those who live in hot countries with lower per capita income but not
requiring heating expenses.
It does not take into account the differences in employment levels between countries.
The per capita income figure may be high in a country where there is a high rate of
unemployment which implies that the majority of the people are not earning and therefore they
are unable to meet the basic necessities of life which leads low standards of living of people yet
in another country the per capita income may be low when the rate of unemployment is very low
i.e. majority of the people are earning a living and therefore can afford the basic necessities of
life which implies better standards of living of such people.
It does not consider the differences in the level of taxation of income/wealth between
countries;
The per capita income may be high in a country where the rate of tax on peoples income is very
high, this reduces their disposable income and therefore lowering their standards of living
because they have less amount of money for buying goods and services yet in another country,
with a lower per capita income, the rate of tax on peoples income may also be low which
implies that people are left with enough disposable income and such income enables them to buy
a number of goods and services which leads to improvement of their standard of living.
It does not take into account of the differences in the transport and distribution costs
of goods between countries.
In a country experiencing higher transport and distribution costs the standard of living tends to
be lower despite its income per capita being higher because of the high costs of obtaining the
goods and services
It does not consider differences in the value of currencies .
The value of the currency of the country with a higher income per capita may be lower implying
a lower standard of living because such a currency purchases a smaller quantity of goods and
services compared to the one of a country with a lower income per capita but of a higher value
.
It does not consider differences in the boundary of production .
Some activities may be left out when compiling national income in a country with a lower
income per capita yet they improve peoples welfare which results into a higher standard of living
compared to another country with a higher income per capita but where very many activities are
considered in computation of national income
It ignores differences in tastes and preferences between the countries
In a country where the goods produced and considered are not the ones preferred by the people
the standard of living is likely to be lower although its income per capita is higher yet in another
country with a lower per capita income but where the goods produced are the ones preferred the
standard of living happens to be higher
©Economics department 45
Limitations/weaknesses of using per capita income to compare standards of living in a
country over time:
It does not consider changes in income distribution in economy overtime.
In a period when per capita income is high but there may be wide income disparities, implying
that the majority of the people are not in position to buy the basic necessities of life, yet in
another period when per capita income is low there may be even distribution of income implying
that the majority of the people are in position to buy the basic necessities of life and thus better
standard of living.
It does not consider changes in the quality of goods produced in economy overtime.
In a period when per capita income is high there may be production of poor quality products
which leads to low standard of living, yet in a period when per capita income is low there may be
production of high quality goods and better standard of living.
It does not consider the changes in the degree of accuracy of the statistical data in an
economy over time.
In a period when the per capita is high there may be inaccurate statistical data e.g. wrong
population figures which may not give a good picture of people’s standard of living, yet in
another period the per capita income may be low when there is accurate statistical data and
people enjoy better standard of living
It does not consider the changes in tastes and preferences in an economy over time.
In a period when per capita income is high, the goods and services produced may not favour
people’s tastes and preferences thus low standards of living yet in another period the per capita
income may be low when the goods and services produced are favourable to the people thus high
standards of living.
It does not consider changes in the price level / inflation in country overtime.
In a period when per capita income is high there may be high rate of inflation which leads to
high cost of living and thus low standard of living, yet in a period when there is low per capita
income there may be low general price levels which leads to low cost of living and thus better
standard of living.
It does not consider changes in the amount of leisure foregone in an economy over
time.
In a period when per capita is high people may be working for very long hours and thus having
very little time for leisure and thus low standard of living, yet in a period when per capita income
is low, people may be working for fewer hours and therefore having ample time for leisure, thus
a better standard of living.
©Economics department 46
It does not consider changes in the pattern of government expenditure in an economy
over time.
In a period when per capita income may be high but when the government spends her income
mostly on activities which are not directly productive and therefore not improving the standard
of living of the people e.g. heavy expenditure on the military hard ware/military sector, yet in a
period when per capita income may be low the government may be spending her income mostly
on activities which are directly productive and therefore improving the standard of living of the
people.
It does not take into account changes in the composition/types of goods produced in
an economy overtime.
In a period when per capita income may be high there may be more capital goods produced
which do not improve people’s welfare directly and thus low standard of living, yet in a period
when per capita income is low there may be production of more consumer goods which improve
people’s welfare directly and thus a better standard of living.
It does not take into account changes in the political climate in economy overtime.
In a period per capita income is high there may be wars/insecurity in the country which
negatively affects people’s welfare, yet in a period when per capita income is low there may be
high levels of security of live and property and thus better standard of living.
It does not take into account changes in the level of taxation on income/wealth
overtime
. In a period when per capita income is high there may be high levels of taxation on people’s
income/wealth which reduces their disposable income leading to low volume of goods and
services enjoyed by such people thus low standard of living, yet in a period when per capita
income is low there may be low levels of taxation on people’s income/wealth which leads to high
level of disposable income leading to high volume of goods and services enjoyed by such people
and thus better standard of living.
It does not take into account changes in the level of employment/unemployment level
in economy overtime.
In a period when per capita income is high there may be high levels of unemployment due to
heavy use of capital intensive technology implying that majority of the people are unable to buy
the basic necessities of life since they are not earning and thus low standard of living, yet in a
period when per capita income is low there may be high employment levels in the economy and

thus majority of the people are in position to meet the basic necessities of life due to the incomes
earned and thus better standard of living.
It does not take into account changes in the working conditions in an economy over
time.
In a period when per capita income is high, there may be high levels of occupational hazards
which negatively affect people’s standard of living, yet in a period when per capita income is
low there may be low levels of occupational hazards leading to better standard of living of the
people.
Question (a) Distinguish between per capita income and personal income
(b) Explain why an increase in a country`s per capita income may not necessarily
High national income/GDP figures imply a high standard of living while low national income
/GDP figures imply a low standard of living. However this may not always be correct because
like per capita income, national income or GDP figures ignore the same factors that greatly affect
people`s standards of living
Solution;
They ignore differences in the price levels of goods and services between the countries
They ignore differences in the distribution of income in the different countries
The national income figures ignore differences in the political climate between the
countries

The cost of living refers to the amount of money required by an individual to sustain the
standard of living/lifestyle he/she is accustomed to. The cost of living depends on the general
price level of goods and services in that if the price level is high then the cost of living is high,
and if the price level is low , then the cost of living is low.
©Economics department 48
If the cost of living is high then the standard of living turns out to be low because the goods and
services are expensive and unaffordable for most people, but if the cost of living is low the
standard of living tends to be high
The cost of living/changes in the cost of living are measure by calculating the changes in the
general price level which is done by use of price indices.
Price indices are numbers/figures used to measure the average change in prices of a basket of
goods and services from the base year to the current year
A base year is a year when prices were relatively stable and therefore the price index for the
base year is always 100. The current year is the year for which the prices are being compared
with the stable prices of the base year i.e the price index that is computed is for the current year.
The price index computed (for the current year ) may be greater than 100 indicating that on
average the general price level increased from the base year to the current year, but it may be less
than 100 indicating that on average the price level reduced in the current year compared to that in
the base year. If the computed price index is equal to 100, then on average the price level in the
current year remained the same as that in the base year
This is a ratio of the current year price to the base year price of one commodity.
This is a figure that measures relative changes in the retail prices of consumer goods over a
period of time
This is a figure that measures relative changes in the retail prices of commodities in an economy
from one time period to another
©Economics department 49
This is a figure that measures relative changes in the wholesale prices of commodities in an
economy over a period of time
This is a price index computed that does not take into consideration of the weights/relative
importance of the commodities in the basket of goods
Weighted (price)index
This is a price index is a price index/statistical measure that takes into consideration of the
weights/relative importance of the commodities in the basket of goods

Calculation of the average weighted price index
AWPI =
∑ Weighted price index for each commodity
∑ Weights
Or
∑ (Price relative x weght )
∑ Weights
Example:
1(a) Study the table below and answer the questions that follow.
Commodity Prices in year Price index for Prices in year 2001 Weight.
2000 year 2000 (shs)
(shs)
i) Calculate the simple price index for each commodity in 2001. (04 marks)
iii) The weighted price index for each commodity in 2001. (04 marks)
(b) Explain the challenges encountered in computation of price indices in Uganda (08 marks)
SOLUTION
From the table the base year is year 2000 (because that the year where the price index for each
of the commodities is indicated as 100)

(ii)Average simple price index for the year 2001(simple price index/un weighted index for the
year 2001)
ASPI =
∑ Price relatives =
116.7+125+ 75+100 416.7
= = 104.175 =104.2
Nunber of commodities 4 4
(iv)Average weighted price index for year 2000(weighted index for year 2000)
AWPI =
∑ Weighted price indices = 466.8+375+150+ 100 = 1091.8 = 109.18 = 109.2
∑ Weights 1+ 2+ 3+4 10

The Gini coefficient/index is a statistical measure of the degree of income inequality that ranges
between 0 and 1 where by the bigger its magnitude, the greater the degree of income inequality
The Lorenz curve and Gini index are used to;
Measure the degree of income inequality in an economy at a particular period of time
Compare the income inequality/distribution of income in different countries
Find out changes in the distribution of income in an economy over time

Causes of income inequality/uneven distribution of incomes and wealth
Question; (a)Account for the uneven distribution of income and wealth in developing
countries.
(b)Explain the implications of existence of income inequality in developing
countries.
Differences in the level of education and skills/training. Highly educated individuals
earn higher incomes because they tend to be more efficient in production and thus
produce more output but those with low levels of education and skills earn lower incomes
because they are less efficient in production end therefore produce low output
Differences in natural resources endowment. People who live in areas which are
endowed with abundant natural resources produce more goods and services which help
them to earn more income than those who live in areas which are endowed with less
natural resources who produce lower output
Differences in talents and natural abilities. People with special abilities like artistes,
soccer stars etc get higher incomes than those without such abilities because they posses
rear skills that make them more efficient and productive
Differences in family/social background. People who come from rich families get higher
income than those from poor families because they are able to inherit income generating
assets unlike their counterparts from the poor families
Differences in the amount of output produced; People who produce more output earn
more income than their counter parts that produce less output in case they are paid
according to the output produced(peace rate)
Differences in the elasticity of supply of labour; Labourers with inelastic supply earn
higher income due to the fact that it is not easy to acquire such labourers which leads to
low labour supply yet those with elastic supply earn low income because it is very easy to
acquire them whenever the need arises
Differences in trade unions ability to bargain; Workers who are organized under strong
trade unions get higher incomes because such trade unions are able to use various
methods to compel the employer to increase their pay unlike for those who are members
of weak trade unions
Differences in employer’s ability and willingness to pay; workers whose employers have
the financial ability and willingness to pay better wages earn higher incomes than their
counterparts whose employers do not have the financial ability to pay better wages
©Economics department 57
because their employer make profits that enable the employer to give workers a higher
pay
Differences in the accessibility to developed infrastructure; People who live in areas
with well-developed infrastructure in terms of roads, railways, banks carry out a number
of economic activities because of the low costs of production which help them to earn
higher incomes than their counterparts who live in areas with poor infrastructure or less
developed infrastructure who are unable to produce enough output because of high costs
of production
Discrimination in the labour market on the basis of gender, race, age, or religion.
Individuals who are discriminated at places of work get lower incomes because they are
of the unfavoured race, religion etc but those that are favoured get higher incomes
because they are of the desired race or religion
Differences in the nature of occupations. People who are employed in highly risky jobs
get higher incomes because of low supply of labour to those occupations unlike those
employed in less risky jobs who get low incomes because of the high supply of labour to
those jobs
Differences in the ability of individuals to bargain for incomes. People with high
bargaining power earn high income because they are to convince their employers to give
them better incomes than those with low bargaining power who fail to convince their
employers to give them better incomes.
Differences in the number of hours worked. People who work for long hours earn
higher incomes than those who work for a few hours in case of time rate system of wage
payment because they are able to produce more output.
Differences in the cost of living: People who work in areas where the cost of living is
high e.g. in urban areas tend to earn higher incomes to enable them afford goods and
services which are expensive compared to those working in areas where the cost of living
is low.
Differences in access to credit facilities /contracts. People who have access to credit
facilities and able to use up such facilities to start income generating activities, earn
higher incomes than their counterparts who do not have easy access to such facilities and
therefore earn low incomes.
Differences in the degree of political climate/state of security: People living in areas
which are politically stable are able to carry out a number of economic activities which
help them to earn higher incomes because they are assured of the security for their lives
and property unlike those who live in areas which are politically unstable who are unable
to effectively engage in economic activities because of the constant fear of loss of lives
and property leading to low incomes earned .
Non-matching wage policy by the employers. Employers especially government pays
their workers different wages depending on the nature of the assignments/departments
where they are deployed. Workers in departments which are favoured by the employers
tend to earn more incomes than those deployed in less favoured departments.

Political influence in the allocation of resources in favour of certain regions/sectors.
People in those areas favoured in terms of resource allocation for infrastructural
development, industrial establishment, job creation are in position to engage in a number
of economic activities which are highly paying hence earn higher incomes than those
who stay in areas which are not favoured in terms of infrastructural development, and job
creation who fail to engage in different economic activities and thus leading to low
incomes earned by such people.
Differences in the level of experience/expertise/seniority/responsibility. People with a
high level of experience get higher incomes because they tend to be more efficient and
therefore able to produce more output and of better quality compared to those with
limited experience.
Differences in elasticity of demand for the product that labour produces. People
producing commodities that have inelastic demand get higher incomes because its
possible cover up the costs of the high payment by increasing prices of the final products
without greatly reducing sales unlike those who produce commodities that have elastic
demand

Leads to rural urban migration and the associated evils. The low income earner tend
to move to urban areas looking for better paying opportunities to increase their earnings
Leads to low aggregate demand/small market. Many of the low income earners are
unable to purchase enough goods and services which discourages investment
Makes government unpopular/leads to resentment towards government. The low
income earners blame government for failing to help them to come out of the miserable
conditions
Leads to high government expenditure. This is on provision of social services like
health care and education for the poor
Leads to brain drain. Low income earners with high level of skills move to work in
other countries so as to get higher incomes
Leads to low tax revenue for government. Many of the poor don’t pay direct taxes
because of very low or no incomes
Leads to exploitation of the poor by the rich. This is through underpaying them
because they are usually desperate.
Results into social evils like thefts and prostitutions as the low income earners try to
look for money to sustain their livelihood
Leads to low savings because the poor have low marginal propensity to save
Leads to apathy among the poor. This is because the low incomes discourage them
from working hard
Leads to a high dependency burden because the poor depend on their rich relatives and
friends when it comes to education and medical care for their families
Leads to low standards of living among the poor because they are unable to purchase
and enjoy enough goods and services
Leads to creation of social classes. That is those for the poor and those for the rich
which leads to social tensions
Leads to misallocation of resources because business people tend to produce and import
more of luxuries for the rich instead of essential goods for the poor

Modernize agriculture. This will enable farmers produce more output for commercial
purposes and be able to earn more incomes
Provide affordable credit. This will avail the low income earners with funds to purchase
inputs for investment and be able to create employment for themselves and others and
hence generation of more incomes for the poor
Control the population growth. This will reduce the dependency burden, encourage
saving and investment which will increase income generating activities for the poor
people in the country
Decentralize governance. This will transfer power and decision making from the center to
the local authorities to and enable them invest in infrastructure and job creation for the
people in different localities for them to earn incomes
Ensure political stability. This will ensure security for lives and property which will
facilitate more investments and create more jobs for the unemployed poor to increase
their incomes
Government should subsidize the poor e.g when it comes to education to enable them
acquire skills for employment and income generation.
Reform the land tenure system. This will make land more accessible for investment
purposes and therefore create more employment opportunities for income generation
Encourage diversification of the economy. This will increase the number of investments
and economic activities in the different sectors of the economy and hence create more
employment opportunities for income generation.
Encourage liberalization of the economy. This will lower production costs and hence
attract more investments and create jobs for the unemployed poor for them to earn more
incomes
Raise wages of low income groups. This will enable the low income earners save part of
their incomes for investment and income generation
Encourage development of small-scale industries/ enterprises. This create more
employment opportunities as they use labour intensive methods of production and
eventually raise incomes for a large number of poor people
Continue empowering disadvantaged groups. This will enable them access education
and training, credit facilities and employment and therefore enable them participate in
income generating activities
