Demand estimation
Production of a good or supplying of product to
the market depends on correct estimation of
demand in case of incorrect estimation of demand
firm would decrease the profit
Similarly excess supply of product to the market
tends to fall the price of good, and profit margin
of a firm would decline
Direct Methods of Demand Estimation
Consumer interviews
Range from stopping shoppers to speak with
them to administering detailed questionnaires
Potential problems
Selection of a representative sample, which is a sample
(usually random) having characteristics that accurately
reflect the population as a whole
Response bias, which is the difference between responses
given by an individual to a hypothetical question and the
action the individual takes when the situation actually
occurs
Inability of the respondent to answer accurately
Direct Methods of Demand Estimation
Market studies & experiments
Market studies attempt to hold everything constant
during the study except the price of the good
Lab experiments use volunteers to simulate actual
buying conditions
Field experiments observe actual behavior of
consumers
Demand estimation through marketing
Research
We can estimate demand through the following
techniques
Consumer surveys and observational Research
Consumer Clinics
Market Experiments
Consumer surveys and observational
Research
•The survey conducted at a big shopping centers by trained
interviewers with sophisticated questions
•Consumers questionnaires provide useful information to
the firm
Sample questionnaire for survey
Do you know how much your monthly consumption of
Coke would change if
price of Coke rose by 10%
your income increase by 20%
Coke producer doubled its advertising expenditures
caffeine content of Coke were reduced by 1% point
price of competitor product (Coke) reduced by 2%
Demand estimation through marketing Research
approach (cont….
•Through giving answer of these questions manager can
get a rough idea about the market demand
•Some time consumers are unable or unwilling to provide
accurate information
•In this case manager is not able to estimate the market
demand, so consumer survey is replace by observational
research
Observational research:
This refers to the gathering of information on consumer
preferences by watching them buying and using goods
However consumer survey is useful and is the only way
to obtain information about possible consumer response
Especially if a firm is thinking of introducing a new
product or changing the quality of an existing one
The only way that the firm can test consumer reaction is
to directly ask them, since no other data are available
Consumer Clinics
•Another approach to estimate demand is consumer
clinics
These are laboratory experiments in which the
participants are given a sum of money and asked to
spend it in a simulated stores to see the react , but
Change the price of product in different stores
Different product packing in different stores
Different product displays in different stores
Different price of competing product in different
stores etc
•Disadvantages of this method:
•In order to keep costs down, the experiment is likely to be conducted on
too limited a scale
•The experiment is conducted for short period of time
•So inference or results about entire market and or more extended period
of time are questionable
•Irregular factors such as strike or bad weather seriously effect the result
•Demand estimation through marketing Research approach (cont….)
Advantages of the Methods
Participants have the incentive to purchase the
commodities they want the most
This method is more realistic than consumer survey,
because in this method we are observing the actual market
behavior
Shortcomings of this method
The results are questionable because participants know
that they are in an artificial situation and that they are being
observed
So they are not likely to act normally
The sample of participants must necessarily small
because of the high cost of running the experiment
Inference or results from small sample are dangerous
Market Experiments
Market experiments are conducted in the actual market
place
There are many ways of performing market experiments
One way is to select several markets with similar
socioeconomic characteristics
Market experiments can be conducted by
Changing the commodity price in some markets or stores
Packing in other markets or stores
Different amount of promotion in the markets and stores
Then record the response (purchase) of consumers in the
different markets
By using census data or survey for various markets, a firm
can also determine the effect of age ,sex, level of education,
income, family size and so forth on demand for the
commodity
•Advantages of this method
We can ensure the validity of the results by conducting on
a large scale
Consumers act /behavior is normal as consumers are not
aware that they are part of an experiment
Disadvantages of this method:
In order to keep costs down, the experiment is likely to be
conducted on too limited a scale
The experiment is conducted for short period of time
So inference or results about entire market and or more
extended period of time are questionable
Irregular factors such as strike or bad weather seriously
effect the result

Competitors could try to sabotage the experiment by changing
prices and other determinants of demand under their control
Competitors also monitor the experiment and gain useful
information that the firm would prefer not to disclose
Firm might permanently lose customers in the process of
raising prices in the market where it is experimenting with a
high price
