1. Enlist and explain different features of international trade as compared to domestic trade.

International trade refers to the exchange of goods and services across international borders, whereas domestic
trade takes place within the boundaries of a single country. The following are the key features that distinguish
international trade from domestic trade:

1. Geographical Scope:
International trade occurs across nations, while domestic trade happens within one country. It involves
more complexity due to distance, time zones, and diverse regions.
2. Currency Difference:
International trade involves multiple currencies, necessitating foreign exchange conversion. Domestic
trade uses the national currency only.
3. Legal and Political Environment:
International trade is affected by diverse legal systems, trade policies, and political relations among
countries. Domestic trade follows a single legal system and unified national policy.
4. Customs Duties and Tariffs:
International trade is subject to import and export duties, tariffs, and quotas. These barriers don’t exist in
domestic trade.
5. Transport and Communication Cost:
International trade involves high transportation costs, longer transit time, and more complex logistics as
compared to domestic trade.
6. Risk Factor:
Risks such as exchange rate fluctuations, political instability, and differing regulations make
international trade riskier than domestic trade.
7. Language and Cultural Differences:
International trade faces challenges related to different languages, traditions, and business etiquettes.
These do not apply to domestic trade.
8. Documentation Requirements:
International trade requires detailed documentation like bills of lading, letters of credit, and customs
forms, unlike domestic trade which is simpler in paperwork.

In conclusion, international trade is broader, more complex, and riskier due to involvement of different
countries, currencies, legal systems, and trade regulations.

2. Differentiate between domestic and international trade. Also write a note on the importance of
international trade.

Difference between Domestic and International Trade:

Aspect Domestic Trade International Trade

Geographical Scope Within a country Between two or more countries
Currency Single national currency Multiple currencies involved
Legal System Same laws and regulations Different legal systems and trade laws
Transport Costs Generally lower Higher due to long distances and customs
Language and Culture Common language and culture Differences in language and cultural values
Trade Barriers None or minimal Tariffs, quotas, and non-tariff barriers
Market Familiarity High, due to local knowledge Less, due to foreign market conditions

Importance of International Trade:

1. Access to Resources:
No country is self-sufficient. International trade allows access to natural resources, technology, and
goods not available domestically.
2. Specialization and Efficiency:
Countries can specialize in what they produce best and trade for the rest, improving global resource
allocation.
3. Economic Growth:
Export earnings contribute to GDP and help develop industries, creating jobs and income.
4. Technology Transfer:
International trade encourages the flow of knowledge, innovation, and advanced technology, especially
from developed to developing countries.
5. Consumer Benefits:
Consumers enjoy more choices, better quality, and competitive prices due to global competition.
6. Political and Economic Relations:
Trade promotes diplomatic cooperation and peaceful international relations by making countries
economically interdependent.
7. Foreign Exchange Earnings:
Trade brings in foreign currency, helping countries stabilize their balance of payments and import
essential goods.

In conclusion, international trade is vital for economic development, better living standards, and integration into
the global economy. It transforms not only economies but also international relationships.

3. Briefly discuss the importance of international trade?

International trade is crucial for the economic growth and development of countries. It allows nations to
specialize in the production of goods and services in which they have a comparative advantage, leading to more
efficient allocation of resources globally. By exchanging products, countries can enjoy a wider variety of goods
than they could produce domestically, enhancing consumer choice and living standards.

Moreover, international trade fosters competition, which encourages innovation, productivity improvements,
and technological progress. It also helps countries access raw materials, capital goods, and technologies that
may not be available domestically, promoting industrial development.

Trade contributes to economic growth by expanding markets for domestic producers, increasing exports, and
generating foreign exchange earnings necessary for importing essential goods and services. It also helps
countries diversify their economies, reducing dependence on a limited range of products.

In addition, international trade strengthens diplomatic and economic relations among countries, promoting
peace and cooperation. For developing countries, trade offers opportunities to integrate into the global
economy, attract foreign investment, and accelerate development.

In summary, international trade is vital for economic efficiency, growth, technological advancement, and global
cooperation, making it a key pillar of modern economic policy.

4. In the case of Pakistan, Does international trade follow the classical theory of absolute advantage or
the theory of comparative advantage? Discuss in detail.

Pakistan’s international trade structure aligns more closely with the theory of comparative advantage rather
than absolute advantage. The classical theory of absolute advantage, proposed by Adam Smith, suggests that a
country should produce and export goods it can produce more efficiently (at a lower absolute cost) than others.
In contrast, David Ricardo's comparative advantage theory argues that countries should specialize in goods they
can produce at a lower opportunity cost, even if they are less efficient in absolute terms.

Pakistan, being a developing country with limited industrial advancement, lacks absolute advantages in many
sectors compared to industrialized nations. For example, Pakistan cannot produce high-tech machinery or
electronics more efficiently than countries like Germany or Japan. However, it has a comparative advantage in
producing textiles, agricultural goods (like rice and cotton), and sports goods due to lower labor costs and
favorable climate.

Pakistan imports oil, machinery, and chemicals—products where other countries have comparative and
sometimes absolute advantages. It exports goods in which it is relatively more efficient, given its resource
endowments and workforce skills. This trade pattern supports the theory of comparative advantage.

Additionally, trade agreements such as GSP+ with the EU enhance Pakistan's export competitiveness in sectors
where it holds comparative advantage. Hence, Pakistan’s trade policies and patterns largely validate Ricardo’s
theory by focusing on specialization and exchange based on relative efficiency rather than absolute
productivity.

5. Explain Adam Smith's theory of absolute advantage with suitable examples in detail.

Adam Smith’s Theory of Absolute Advantage is one of the earliest theories of international trade, introduced
in his 1776 book "The Wealth of Nations." The theory emphasizes that countries should specialize in producing
goods in which they have an absolute advantage—that is, the ability to produce more of a good with the same
amount of resources than another country.

Core Idea:
A country should export goods it can produce more efficiently (at a lower cost or using fewer resources) and
import goods that other countries produce more efficiently.

Example:
Consider two countries: Pakistan and Japan, and two products: cotton and cars.

Country Cotton (units per worker) Cars (units per worker)

Pakistan 10 2
Japan 4 8

 Pakistan has an absolute advantage in producing cotton because it produces 10 units compared to
Japan’s 4.
 Japan has an absolute advantage in producing cars because it produces 8 units compared to Pakistan’s
2.

3|Page
According to the theory:

 Pakistan should specialize in producing and exporting cotton.

 Japan should specialize in producing and exporting cars.
 They should then trade with each other to obtain what they do not produce efficiently.

Benefits of Absolute Advantage:

1. Increased Global Output: Specialization leads to higher production overall.

2. Efficient Resource Allocation: Resources are used where they are most productive.
3. Lower Costs: Consumers benefit from cheaper goods.
4. Mutual Gains from Trade: Both countries can consume more than without trade.

Limitation:
This theory doesn’t explain trade when one country has an advantage in all goods. That’s where Ricardo’s
comparative advantage theory fills the gap.

In summary, Adam Smith’s theory promotes free trade and specialization based on efficiency, laying the
foundation for modern trade economics.

6. Write four assumptions of the law of comparative advantage.

The law of comparative advantage, introduced by David Ricardo, explains how countries can gain from
international trade by specializing in the production of goods where they have the lowest opportunity cost. To
demonstrate the principle effectively, the model is based on several simplifying assumptions, which help in
understanding the core logic of the theory.

1. Two Countries and Two Goods:

The theory assumes that only two countries are involved in the trade, and each country produces only
two goods. This simplification helps in easy comparison of opportunity costs and trade patterns,
although in reality, trade involves multiple countries and a variety of goods.
2. Labor as the Only Factor of Production:
It is assumed that labor is the only resource used in the production of goods. This labor is fully
employed, homogeneous in quality, and mobile within a country but immobile between countries. This
assumption ignores the role of capital, land, and technology in real-world production.
3. Constant Returns to Scale:
The model assumes that the production of goods has constant returns to scale, meaning that doubling the
input will exactly double the output. This implies stable opportunity costs and simplifies comparative
analysis, though in reality, economies and diseconomies of scale are common.
4. No Transportation Costs or Trade Barriers:
It is assumed that there are no transport costs, tariffs, or quotas involved in international trade. Goods
can move freely between countries. This assumption is idealistic, as trade in the real world often
involves costs, time delays, and various policy restrictions.

These assumptions help isolate the effect of comparative advantage in explaining trade benefits. Although
unrealistic in some respects, they form the basis for more advanced trade theories.

4|Page
7. Differentiate between the concept of Heckscher–Ohlin theory and his theorems. Also, explain his price-
equalization theorem in detail.

Heckscher–Ohlin Theory (H–O Theory) is an extension of comparative advantage. It suggests that countries
export goods that use their abundant and cheap factors of production and import goods that require factors in
which they are scarce. For instance, a labor-abundant country will export labor-intensive goods and import
capital-intensive ones.

The main concept of the theory is factor endowment: the availability of labor, land, and capital in a country
determines its trade pattern. The theory assumes two countries, two goods, and two factors of production
(2x2x2 model).

Heckscher–Ohlin Theorems are the outcomes derived from this theory:

1. H–O Theorem: Countries export goods that intensively use their abundant factors.
2. Factor Price Equalization Theorem: International trade will lead to equalization of factor prices
(wages and returns to capital) across countries.
3. Stolper-Samuelson Theorem: An increase in the price of a good raises the income earned by the factor
used intensively in its production.
4. Rybczynski Theorem: An increase in one factor will increase the output of the good using that factor
intensively, and decrease the other.

Price Equalization Theorem (in detail):

This theorem states that free trade will lead to equal wages for labor and equal returns to capital in all trading
nations. This happens because trade acts as a substitute for factor mobility. As countries specialize and trade
based on factor endowment, the demand and supply of those factors adjust globally. For example, a labor-
abundant country will export labor-intensive goods, increasing domestic wages, while the importing country’s
wages may decrease due to reduced demand. Over time, this leads to convergence in factor prices. However, in
the real world, differences in technology, trade barriers, and mobility prevent perfect price equalization.

8. It is generally argued that dissatisfaction with the Heckscher-Ohlin framework has resulted in the
development of several new theories of international trade. Critically evaluate the statement.

The Heckscher-Ohlin (H-O) theory explains international trade based on differences in countries’ factor
endowments—land, labor, and capital. It argues that a country will export goods that use its abundant factors
intensively and import goods that use its scarce factors. However, over time, dissatisfaction with the theory has
emerged due to its inability to explain real-world trade patterns, leading to the development of new trade
theories.

Reasons for Dissatisfaction with H-O Theory:

1. Empirical Contradiction (Leontief Paradox):

In 1953, economist Wassily Leontief found that the U.S., a capital-abundant country, was exporting
labor-intensive goods and importing capital-intensive goods—contradicting the H-O model.
2. Intra-Industry Trade:
The H-O theory cannot explain why countries with similar factor endowments (e.g., Germany and
France) trade similar goods, like automobiles.
3. Assumption of Perfect Competition:
The theory assumes perfect competition and constant returns to scale, which are not realistic in many
modern industries dominated by imperfect competition and increasing returns.
5|Page
 4. Neglect of Technology and Innovation:
It doesn’t account for technological differences and innovation, which play a significant role in trade
today.

New Trade Theories Developed as a Result:

1. Product Life Cycle Theory (Vernon):

Focuses on technological innovation and product development stages.
2. New Trade Theory (Krugman):
Emphasizes economies of scale and consumer preference for variety under monopolistic competition.
3. Strategic Trade Theory:
Introduces the idea of government intervention to support industries with potential comparative
advantage due to economies of scale and R&D.

9. Explain Production Possibility Frontier with Increasing Cost.

The Production Possibility Frontier (PPF) is a graphical representation showing the maximum possible
combinations of two goods or services that an economy can produce with available resources and technology,
assuming full and efficient utilization. When the PPF is drawn with increasing opportunity cost, it takes a
concave shape (bowed outward from the origin).

Explanation of Increasing Cost:

The concept of increasing opportunity cost means that as the production of one good increases, the
opportunity cost of producing that good also rises. This occurs because resources are not perfectly adaptable to
the production of all goods. For instance, workers or machines better suited to producing one good may be less
efficient in producing another. As more resources are shifted toward one product, the less suitable resources are
used, causing inefficiencies and higher costs.

Example:

Consider a country producing only wheat and cloth. Initially, resources that are efficient in producing cloth are
used for cloth, and those suited to wheat are used for wheat. But if the country wants more cloth, it must
reallocate resources from wheat to cloth. As this reallocation continues, resources less suited for cloth
production are used, increasing the cost of producing additional units of cloth.

Graphical Representation:

The concave shape of the PPF illustrates that the trade-off between goods becomes steeper — more units of one
good must be given up to gain additional units of the other.

Conclusion:

The increasing cost PPF shows the reality of limited resources and differing efficiencies, reflecting why
economies face trade-offs. It emphasizes that choices in production come at an increasing cost, which is a
fundamental principle in international trade and economic decision-making.

10. What is the product life cycle theory of international trade? Discuss in detail.

The Product Life Cycle Theory of International Trade, introduced by Raymond Vernon in the 1960s,
explains how a product’s origin and trade pattern evolve over time. The theory divides the life of a product into
four stages: introduction, growth, maturity, and decline, and shows how the location of production and trade
flows shift throughout these stages.

1. Introduction Stage:
A new product is developed and introduced in an advanced country (usually the U.S.). Production is
close to the market and relies on skilled labor. There is little or no international trade at this stage.
2. Growth Stage:
Demand for the product increases both domestically and internationally. Exports from the innovating
country begin. Competitors in other developed countries may also start producing the product.
3. Maturity Stage:
The product becomes standardized. Production processes are simplified and can now be outsourced to
developing countries where labor is cheaper. The original innovating country may begin importing the
product it once exported.
4. Decline Stage:
The product becomes obsolete or replaced by new innovations. Developing countries may dominate
production, and developed countries may move to newer innovations.

This theory highlights how comparative advantage shifts over time. In the early stages, innovation and
technology dominate; in later stages, cost efficiency and scale economies take over. It also explains why some
products are first exported by developed countries but later by developing ones, as production shifts to regions
with lower costs.

11. Do you agree with the view that free trade is the best policy from the view point of economic
development?

Free trade refers to the unregulated exchange of goods and services between countries without tariffs, quotas,
or other barriers. Economists generally argue that free trade promotes efficiency, growth, and development by
allowing countries to specialize based on comparative advantage. However, whether it is always the best policy
for economic development is a matter of debate.

Arguments in Favor of Free Trade:

1. Specialization and Efficiency:

Free trade allows countries to specialize in what they produce best, leading to efficient resource use and
higher output.
2. Consumer Benefits:
It provides consumers with more choices, lower prices, and better quality products.
3. Access to Technology:
Developing countries can benefit from the transfer of advanced technologies through imports and
foreign investment.
4. Foreign Exchange Earnings:
Export-led growth boosts foreign exchange reserves and supports balance of payments.
5. Stimulus for Growth:
Open markets attract foreign direct investment (FDI), increase competition, and drive productivity.

7|Page
Criticisms of Free Trade:

1. Harm to Infant Industries:

New industries in developing countries may fail when exposed to global competition without initial
protection.
2. Deindustrialization:
Over-reliance on imports can weaken domestic industries and lead to unemployment.
3. Unequal Gains:
Benefits of free trade are not always equally distributed—rural areas and unskilled workers may suffer.
4. Vulnerability to Global Shocks:
Open economies can be more exposed to global recessions, pandemics, and price volatility.

Conclusion:
While free trade has the potential to drive economic development, it is not a one-size-fits-all policy. Many
countries have used selective protection and strategic trade policies in early development stages. Therefore, a
balanced approach—combining free trade with targeted protection and strong domestic policies—may serve
development goals better than blind adherence to free trade.

12. What is Terms of Trade?

Terms of Trade (TOT) refers to the rate at which one country’s goods exchange for the goods of another
country in international trade. It is an important concept used to measure the relative price of exports in terms
of imports, indicating how much import goods a country can obtain per unit of export.

Formula:

Terms of Trade =
(Index of Export Prices / Index of Import Prices) × 100

If the TOT value is above 100, it indicates an improvement, meaning a country can import more for each unit of
exports. A value below 100 indicates a deterioration, meaning the country has to export more to purchase the
same quantity of imports.

Types of Terms of Trade:

1. Net Barter Terms of Trade:

Compares the prices of exports and imports.
2. Gross Barter Terms of Trade:
Focuses on the physical quantity of imports and exports.
3. Income Terms of Trade:
Takes into account both price and volume of exports to show how much import capacity the country
earns.

Importance:

 Trade Gains: It helps determine whether a country is gaining or losing from international trade.
 Policy Decisions: Guides governments in setting tariffs and trade agreements.
 Economic Health: A deteriorating TOT may hurt economic development, especially in developing
countries reliant on primary exports.

8|Page
Example:

If Pakistan’s export prices increase while import prices remain stable, its terms of trade improve, allowing it to
import more machinery, oil, or technology for the same amount of exported textiles or rice.

Thus, TOT is a crucial indicator of a nation’s trade strength and its ability to benefit from international trade.

13. Discuss with the help of a diagram how consumer and producer surplus changes due to the imposition
of tariff.

A tariff is a tax imposed on imported goods, which increases their price in the domestic market. This change
affects both consumer surplus and producer surplus.

Before Tariff:

 Domestic price is equal to world price.

 Domestic consumers enjoy lower prices and higher quantity.
 Domestic producers sell less due to cheaper imports.
 Consumer surplus is large, and producer surplus is small.

After Tariff:

 Price of imported goods increases due to tariff.

 Domestic price rises.
 Quantity demanded falls, and domestic production increases.
 Imports decrease.
 Consumer surplus decreases because consumers face higher prices and reduced choice.
 Producer surplus increases because domestic producers sell more at higher prices.
 Government gains revenue from the tariff.
 There is a deadweight loss, representing economic inefficiency.

Diagram Explanation:

 B & D: Deadweight loss (efficiency loss)
 C: Government revenue
 E: Consumer loss
9|Page
  Consumer Surplus Loss: A + B + C + D
 Producer Surplus Gain: A
 Government Revenue: C

Thus, tariffs help producers and governments but hurt consumers and create inefficiencies.

14. What is meant by tariff? Discuss its various forms.

A tariff is a tax imposed by a government on imported goods. It is one of the oldest and most common tools
used in international trade policy to protect domestic industries, generate revenue, and regulate trade flows. By
increasing the cost of imported products, tariffs make domestic goods relatively cheaper, encouraging
consumers to buy locally produced items.

Forms of Tariffs:

1. Ad Valorem Tariff:
This tariff is levied as a fixed percentage of the value of the imported good. For example, a 10% ad
valorem tariff on a $100 product means a $10 tax. It adjusts automatically with price changes.
2. Specific Tariff:
A fixed amount of tax imposed per physical unit of the good, such as $5 per kilogram or $20 per unit. It
remains constant regardless of the product’s value.
3. Compound Tariff:
A combination of ad valorem and specific tariffs. For example, a $2 per unit plus 5% of the value. It
offers more precise control over protection.
4. Protective Tariff:
Imposed primarily to protect domestic industries from foreign competition by making imported goods
more expensive.
5. Revenue Tariff:
Designed mainly to generate income for the government rather than to restrict imports. These are
generally lower tariffs applied to goods that have no domestic competition.
6. Tariff Quota:
A lower tariff rate is applied to imports within a certain quota, and higher tariffs are charged on imports
beyond that quota.

Summary:
Tariffs are key instruments in trade policy, influencing prices, domestic production, and government revenue.
The choice of tariff form depends on policy objectives, economic conditions, and administrative ease.

15. Briefly discuss empirical tests of Heckscher-Ohlin Model.

The Heckscher-Ohlin (H-O) Model predicts that countries will export goods that use their abundant factors
intensively and import goods that use their scarce factors intensively. While the theory is elegant and logical,
several empirical tests have been conducted to assess its validity. The most famous and influential test is the
Leontief Paradox.

10 | P a g e
1. Leontief Paradox (1953):

Wassily Leontief tested the H-O theory using input-output data for the U.S. economy. According to the H-O
model, the U.S., being capital-abundant, should export capital-intensive goods and import labor-intensive ones.
However, Leontief found the opposite: U.S. exports were more labor-intensive, while imports were more
capital-intensive. This contradicted the H-O model and raised doubts about its real-world applicability.

2. Trefler’s Findings (1995):

Daniel Trefler examined the "missing trade" problem and found that the volume of trade predicted by the H-O
model was significantly larger than what actually occurs. He introduced factors like technology differences,
human capital, and consumer preferences, which the basic H-O model ignores.

3. Bowen, Leamer, and Sveikauskas Test (1987):

They tested the H-O model across 27 countries and 12 factors and found that only a small portion of trade
patterns matched the model’s predictions, suggesting that other factors such as technology and scale economies
might be more important.

Conclusion:

While the H-O model provides a foundational understanding of trade patterns based on factor endowments,
empirical evidence shows mixed results, and researchers often consider extensions or alternative models to
better explain real-world trade behavior.

16. It is argued that nowadays non-tariff are more prominent barriers to international trade as opposed
to tariff ones. Do you agree with the statement? Explain.

Yes, I agree that non-tariff barriers (NTBs) have become more prominent than traditional tariffs in
international trade. While tariff rates have generally declined due to trade liberalization under WTO and free
trade agreements, NTBs have increased.

Reasons for NTB Dominance:

1. Regulatory Standards: Countries impose strict health, safety, and environmental standards that restrict
imports. These technical barriers are harder to challenge under WTO rules.
2. Quotas: Limiting the quantity of imports without directly taxing them restricts trade more subtly than
tariffs.
3. Subsidies: Domestic industries receive government support, making their goods cheaper, reducing
competitiveness of imports without using tariffs.
4. Customs Procedures: Complex inspection, delays, and administrative red tape discourage importers.
5. Licensing and Import Bans: Governments use licensing systems to control and often limit imports,
affecting trade volume.
6. Sanitary and Phytosanitary Measures (SPS): Often used for agricultural and food products, these
measures can restrict trade even without economic justification.

11 | P a g e
17. How do the economic effects of tariff differ from those of an import quota? Explain with the help of
diagram.

Both tariffs and import quotas are trade restrictions used to protect domestic industries by limiting foreign
competition, but their economic effects differ in important ways.

Economic Effects of a Tariff:

 Tariff is a tax on imports, raising the price of imported goods.

 Domestic consumers pay a higher price, reducing quantity demanded.
 Domestic producers benefit from higher prices and increase production.
 The government earns tariff revenue (tax collected on imports).
 There is a deadweight loss due to consumption reduction and inefficient domestic production.

Economic Effects of an Import Quota:

 Quota is a direct limit on the quantity of imports allowed.

 It restricts supply, causing the domestic price to rise.
 Domestic producers benefit from higher prices and expand output.
 Unlike tariffs, the government does not earn revenue from quotas unless import licenses are auctioned.
 Quotas create deadweight loss similar to tariffs.
 Often lead to quota rents—profits captured by license holders or foreign exporters.

Diagram Explanation (General):

 The demand and supply curves represent the domestic market.

 Without trade, the price is high, and quantity low.
 Free trade lowers price to world price Pw, increasing consumer surplus.
 With a tariff, price rises above Pw to Pt, imports decrease from Qd-Qs to a smaller amount.
 Government revenue = tariff × import quantity.
 With a quota, the import quantity is fixed, so price rises to Pq, possibly higher than the tariff price.
 No government revenue unless licenses are sold.
 Deadweight losses occur in both cases.

Summary of Differences:

Aspect Tariff Import Quota

Price Increase Price rises by tariff amount Price rise depends on quota limit
Government Revenue Yes, tariff revenue collected Usually no revenue unless licenses sold
Quantity Control Quantity decreases due to higher price Quantity directly limited by quota
Market Efficiency Deadweight loss due to distortion Deadweight loss and possible market distortions
Rent Distribution Rents go to government Rents go to quota holders or exporters

Both policies reduce imports and raise prices but differ in revenue generation and control mechanisms.

18. Explain Dynamic Technological Differences and Synthesis of Trade Theories.

Dynamic technological differences refer to the variation in innovation rates, technological progress, and
learning abilities among nations over time. These differences play a significant role in shaping international
trade patterns, especially in modern trade theories, which move beyond the classical and factor-based models
like Ricardo’s Comparative Advantage or the Heckscher-Ohlin Theory.

Dynamic Technological Differences:

Countries that innovate faster or adopt new technologies more efficiently can produce goods at a lower cost
or with better quality, giving them a temporary trade advantage. Over time, other countries may catch up by
learning or imitating the technology, shifting comparative advantages and trade patterns.

This idea is supported by:

 Technological Gap Theory (Posner): Trade arises because countries innovate at different speeds.
Innovators export new products until others catch up.
 Product Cycle Theory (Vernon): A new product is first produced and exported by developed
countries. As it matures and standardizes, production shifts to developing countries.

Synthesis of Trade Theories:

Modern economists have attempted to combine classical, neoclassical, and modern theories to explain the
full complexity of trade. This synthesis includes:

 Comparative advantage based on technology (Ricardo)

 Factor endowments (Heckscher-Ohlin)
 Economies of scale and imperfect competition (Krugman’s New Trade Theory)
 Innovation and dynamic learning (technology gap and product cycle models)

Conclusion:

Dynamic technological differences show that trade advantages are not static. They evolve with innovation and
diffusion. By synthesizing traditional and modern theories, economists can better explain real-world trade
patterns, including trade between similar countries and the rise of intra-industry trade.

19. Analyze the recent trends visible in the worldwide pattern of foreign direct investment like MNEs.

In recent years, Foreign Direct Investment (FDI) patterns have evolved significantly due to globalization,
technological innovation, geopolitical shifts, and sustainable development goals. Multinational Enterprises
(MNEs) have adapted their strategies in response to these global changes.

Key Trends in Global FDI Patterns:

1. Shift Towards Developing Economies:

Emerging economies, especially in Asia (like India, Vietnam, and Bangladesh), are attracting increasing
FDI due to cheap labor, growing markets, and improved infrastructure.

13 | P a g e
 2. Technology-Driven Investments:
MNEs are investing more in sectors such as ICT, renewable energy, and digital services rather than
traditional manufacturing. There’s a rise in cross-border mergers and acquisitions in tech firms.
3. Sustainability Focus:
Green FDI is increasing as firms align with environmental, social, and governance (ESG) goals. MNEs
now prefer locations with strong renewable energy potential and green policies.
4. Regionalization Over Globalization:
Post-COVID-19 and due to geopolitical tensions (e.g., US-China trade war), MNEs are focusing on
regional supply chains, reducing overdependence on any single country.
5. Resilience and Diversification:
There is a trend of "China Plus One" strategy, where MNEs seek alternative countries for investment to
reduce risks associated with single-country concentration.
6. Digital FDI and Remote Services:
Digital platforms and service exports are growing rapidly, enabling FDI in services without physical
presence, particularly in fintech, e-commerce, and outsourcing.

In short, FDI is moving toward sustainability, technology, and resilience, with MNEs diversifying investments
across politically stable and business-friendly nations.

20. Critically appraise the theory of foreign direct investment (FDI).

The theory of Foreign Direct Investment (FDI) explains why and how firms invest directly in production or
business activities in foreign countries. FDI theories seek to understand the motives behind cross-border
investments and their economic impact.

Key Theories of FDI:

1. Market Imperfections Theory (Hymer):

Suggests FDI occurs due to market imperfections such as barriers to trade or information asymmetry.
Firms invest abroad to exploit firm-specific advantages (technology, brand) that cannot be sold via
licensing.
2. Internalization Theory:
Firms prefer FDI over licensing to internalize operations and protect proprietary knowledge, reduce
transaction costs, and control quality.
3. Eclectic Paradigm (OLI Framework):
Proposed by John Dunning, it explains FDI based on three advantages:
o Ownership: Firm’s unique assets (technology, brand)
o Location: Benefits from investing in a particular country (cheap labor, natural resources)
o Internalization: Advantage of controlling foreign operations rather than outsourcing.
4. Product Life Cycle Theory:
Suggests firms invest abroad as products mature, moving production closer to new markets to reduce
costs.

Critical Appraisal:

Strengths:

 Explains diverse motivations for FDI, including market access, resource seeking, and efficiency.
 Recognizes the role of firm-specific advantages and location factors.
 The OLI framework provides a comprehensive, flexible approach.
14 | P a g e
Weaknesses:

 Theories often focus on multinational enterprises from developed countries, less applicable to emerging
economies investing abroad.
 Overemphasis on economic motives; social, political, and strategic factors can also drive FDI.
 Difficult to empirically measure or isolate ownership and internalization advantages.
 Changing global dynamics like digitalization and services trade require updated models.

21. Write a detailed note on the Stolper-Samuelson Theorem.

The Stolper-Samuelson Theorem, developed in 1941, is an extension of the Heckscher-Ohlin model of

international trade. It explains the relationship between changes in product prices and factor incomes within a
country. The core idea is that an increase in the price of a good raises the real income (wage or return) of
the factor used intensively in its production, and lowers the real income of the other factor.

Key Assumptions:

 There are two goods and two factors of production (e.g., labor and capital).
 One good is labor-intensive, the other capital-intensive.
 Perfect competition exists.
 Full employment and constant returns to scale are assumed.

Main Statement:

If the relative price of a labor-intensive good increases (e.g., due to trade liberalization or tariffs), the real wage
of labor increases, and the return to capital decreases. Conversely, if the price of a capital-intensive good
rises, capital gains and labor loses.

Example:

Consider a country that exports textiles (labor-intensive) and imports machinery (capital-intensive). If trade
leads to higher textile prices:

 Labor (abundant factor) benefits through higher wages.

 Capital (scarce factor) suffers a decline in returns.

Implications:

 Trade can benefit one group and harm another, even though it increases national income.
 This helps explain opposition to free trade from groups who lose income.
 It supports the idea that income distribution effects are crucial in trade policy.

Conclusion:

The Stolper-Samuelson Theorem provides insight into how trade affects factor incomes, emphasizing that
gains from trade are not equally shared. It remains a foundational concept in international trade theory,
especially in analyzing trade’s impact on inequality.

22. Identify some incentives that the host country should offer to MNEs to increase the inflow of FDI.

To attract Foreign Direct Investment (FDI), host countries must create a favorable business climate through
both financial and non-financial incentives. Below are key incentives that can increase MNE interest:

1. Tax Incentives:
o Lower corporate tax rates
o Tax holidays or exemptions for a defined period
o Reduction in import/export duties
2. Financial Incentives:
o Subsidies for land, utilities, or capital
o Grants for infrastructure development
o Access to low-interest loans or credit
3. Regulatory Incentives:
o Simplified legal procedures for business registration
o Protection of intellectual property rights
o Transparent and stable legal framework
4. Infrastructure Development:
o Reliable transport, electricity, water supply, and internet
o Special Economic Zones (SEZs) with world-class facilities
o Industrial parks near ports and cities
5. Skilled Labor Availability:
o Investment in education and technical training
o Partnership with MNEs for skill development
6. Political and Economic Stability:
o Assurance of security and rule of law
o Stable macroeconomic environment
7. Market Access and Trade Agreements:
o Duty-free access to regional markets
o Membership in trade blocs like ASEAN, SAARC, or EU partnership
8. Ease of Repatriation:
o Freedom to repatriate profits, dividends, and capital without heavy restrictions

Offering a combination of these incentives enhances a country's attractiveness and competitiveness in securing
global FDI inflows.

23. Explain the economic causes and consequences of the international movement of capital through
foreign direct investment (FDI).

Economic Causes of International Capital Movement through FDI:

1. Market-Seeking Motives:
Firms invest abroad to enter new markets, access growing consumer bases, and avoid trade barriers.
2. Resource-Seeking Motives:
Multinational corporations (MNCs) invest in countries rich in natural resources or cheap labor to lower
production costs.
3. Efficiency-Seeking Motives:
To optimize global production by exploiting differences in factor costs, technology, and infrastructure.
4. Strategic Asset-Seeking:
Firms acquire technology, brands, or managerial skills by investing in foreign companies.
16 | P a g e
 5. Avoidance of Trade Barriers:
FDI helps firms bypass tariffs, quotas, and other restrictions by producing locally.

Economic Consequences of FDI:

1. Positive Consequences:
o Capital Inflow: Supplements domestic savings and investment.
o Technology Transfer: Brings advanced technology and management skills.
o Employment Generation: Creates jobs and improves labor skills.
o Export Promotion: Enhances foreign exchange earnings through exports.
o Infrastructure Development: Encourages improvement in local infrastructure.
2. Negative Consequences:
o Profit Repatriation: A significant portion of profits may be sent back to the investor’s home
country.
o Market Dominance: Foreign firms may dominate local markets, stifling domestic
entrepreneurship.
o Cultural and Political Influence: Potential loss of sovereignty or cultural identity.
o Environmental Concerns: Some MNCs may exploit lax regulations, causing environmental
damage.

Summary:

The international movement of capital through FDI is driven by firms’ strategic motives and has profound
economic impacts. While it can boost development through investment, technology, and jobs, it also raises
challenges that require careful policy management to maximize benefits and minimize risks.

24. Discuss briefly Other Nontariff Barriers and the New Protectionism.

Non-Tariff Barriers (NTBs) are trade restrictions other than tariffs that countries use to control the amount of
trade across their borders. These barriers have gained prominence in recent years as global trade agreements
have reduced traditional tariff rates. NTBs are often less visible but can be equally or more restrictive.

Common Non-Tariff Barriers:

1. Import Quotas – Limit the quantity of a good that can be imported.

2. Voluntary Export Restraints (VERs) – Agreements where an exporting country limits its exports.
3. Technical Barriers to Trade (TBTs) – Include product standards, safety, health, and labeling
requirements.
4. Licensing Requirements – Importers must obtain licenses, sometimes used to restrict quantity.
5. Customs Procedures and Bureaucratic Delays – Slow or complicated import processes discourage
foreign goods.
6. Subsidies to Domestic Producers – Make domestic goods cheaper and foreign goods less competitive.

The New Protectionism: New Protectionism refers to the modern shift from traditional tariffs to NTBs. It often
disguises protectionist policies under the guise of environmental, health, or safety regulations. For example, a
country may ban certain food imports by citing safety standards, while the actual motive is to protect domestic
agriculture.

17 | P a g e
Reasons Behind New Protectionism:

 To protect declining industries (e.g., steel, textiles).

 To preserve jobs in sectors vulnerable to foreign competition.
 To respond to unfair trade practices like dumping or subsidies.
 To address national security or health concerns.

Conclusion:

NTBs and new protectionist measures have become dominant tools in international trade policy. While often
justified on regulatory grounds, their real intent may be economic protection, making them controversial in
global trade negotiations.

25. Critically appraise the various economic integration movements that emerged both in developed and
developing countries.

Economic integration refers to agreements among countries to reduce or eliminate trade barriers and
coordinate monetary and fiscal policies. It can range from free trade areas to full economic unions. Integration
movements have emerged in both developed and developing regions with varied objectives and outcomes.

In Developed Countries:

1. European Union (EU):

One of the most advanced integration models, the EU began as a customs union and evolved into a full
economic and monetary union with a common currency (Euro). It promotes free movement of goods,
services, labor, and capital. However, challenges like Brexit and economic disparities among member
states highlight structural weaknesses.
2. North American Free Trade Agreement (NAFTA) (now USMCA):
Initially promoted trade between the U.S., Canada, and Mexico. It eliminated most tariffs and
encouraged investment. The updated USMCA includes stricter labor and environmental regulations,
addressing concerns of exploitation and inequality.

In Developing Countries:

1. ASEAN (Association of Southeast Asian Nations):

Focuses on economic cooperation among Southeast Asian nations. Though progress is slower compared
to EU, ASEAN has improved regional trade and investment flows.
2. SAARC (South Asian Association for Regional Cooperation):
Aimed at promoting regional cooperation among South Asian countries. Progress is limited due to
political tensions, especially between India and Pakistan.
3. African Continental Free Trade Area (AfCFTA):
A recent initiative aiming to boost intra-African trade. Infrastructure deficits, political instability, and
weak institutions pose major hurdles.

Critical Appraisal:
While economic integration can boost trade, investment, and regional stability, it often faces issues like unequal
gains among members, political conflicts, and lack of enforcement. Developed regions have succeeded due to
stronger institutions, while developing countries struggle due to weak governance and economic disparities.

18 | P a g e
26. Define the term economic integration. Also discuss its various forms.
Economic integration refers to the process by which countries remove trade barriers and coordinate their
economic policies to increase economic cooperation and interdependence. The goal is to create a larger, more
efficient market that benefits member countries through increased trade, investment, and economic growth.

Various Forms of Economic Integration:

1. Free Trade Area (FTA):

Member countries eliminate tariffs and quotas among themselves but maintain independent trade
policies with non-members.
Example: North American Free Trade Agreement (NAFTA).
2. Customs Union:
It includes all the features of an FTA plus a common external tariff on imports from non-members.
Example: Southern Common Market (MERCOSUR).
3. Common Market:
A customs union with the additional free movement of factors of production such as labor and capital
among member countries.
Example: European Economic Community (EEC) in its early form.
4. Economic Union:
A common market with harmonized economic policies, including fiscal and monetary policies, often
involving shared institutions.
Example: The European Union (EU) represents an economic union with a common currency (Euro) used
by some members.
5. Political Union:
The most advanced form, involving economic integration plus political integration, where member states
may adopt a common government.
Example: The United States of America is often cited as a political union.

Summary:

Economic integration ranges from simple trade liberalization (FTA) to full political and economic unification
(political union). The deeper the integration, the more sovereignty member countries may need to share or give
up, but the greater the potential economic benefits through larger markets and coordinated policies.

27. Write details of the Theory of Second Best and Other Static Welfare Effects of Customs Unions.

The Theory of Second Best is a concept in welfare economics that applies directly to the analysis of customs
unions. It states that if one optimal condition for economic efficiency cannot be satisfied, then trying to satisfy
other optimal conditions may not lead to the best possible outcome. In the context of trade, this means that
forming a customs union—while improving some aspects of trade—may not always result in global economic
efficiency.

Customs Union and the Second Best Theory:

A customs union is a trade bloc where member countries remove tariffs among themselves and adopt a common
external tariff against non-members. While this leads to trade creation, it may also result in trade diversion.

 Trade Creation occurs when lower-cost imports from a member country replace higher-cost domestic
production, improving welfare.
19 | P a g e
  Trade Diversion happens when lower-cost imports from a non-member are replaced by higher-cost
imports from a member country due to preferential treatment—this reduces efficiency and global
welfare.

According to the Theory of Second Best, since international trade is already distorted by tariffs, removing them
selectively (as in a customs union) doesn't always lead to the best outcome.

Other Static Welfare Effects:

1. Production Effect: Domestic industries shift to more efficient producers within the union.
2. Consumption Effect: Consumers benefit from lower prices due to tariff elimination within the union.
3. Revenue Effect: Governments may lose tariff revenues, impacting fiscal balance.
4. Terms of Trade Effect: The customs union may gain bargaining power over the rest of the world,
improving its terms of trade.

Conclusion:

The Theory of Second Best helps explain why the creation of customs unions doesn’t always lead to improved
global welfare. The net effect depends on the balance between trade creation and trade diversion, along with
static welfare effects such as efficiency, consumption, and government revenue.

28. Write short notes on the following:

a. Countervailing Duties
Countervailing duties (CVDs) are tariffs imposed by a country to neutralize the negative effects of subsidies
given by foreign governments to their exporters. These duties level the playing field for domestic producers by
raising the price of subsidized imports. They are typically imposed after an investigation proves that imports are
hurting the local industry.

b. Infant Industry
The infant industry argument supports protecting new or emerging domestic industries from international
competition until they become mature and competitive. Protection is provided through tariffs or subsidies. Once
the industry stabilizes, these protections are expected to be removed. However, prolonged protection may lead
to inefficiency and lack of innovation.

c. International Subcontracting
International subcontracting is when firms from developed countries contract specific components or tasks to
firms in developing countries. It is common in manufacturing (like garments, electronics). It helps reduce costs
and utilize specialized skills. However, it may lead to dependency, low wages, and limited technology transfer
in the host country.

d. Balance of Payment
The balance of payment (BoP) is a record of all economic transactions between residents of a country and the
rest of the world over a period. It includes the current account (trade in goods and services), capital account
(investments), and financial account (reserves, loans). A surplus indicates more inflows than outflows, while a
deficit suggests the opposite. It reflects the economic stability and competitiveness of a nation.

20 | P a g e
29. Explain the effects of trade restrictions from the importing country’s point of view on the following:

a. Terms of Trade:
Trade restrictions like tariffs or quotas can improve the importing country's terms of trade by reducing the
volume of imports and thereby lowering the price paid for foreign goods relative to export prices. However, if
other countries retaliate, the terms of trade may worsen, leading to trade wars and reduced gains from trade.

b. Employment:
Trade restrictions protect domestic industries from foreign competition, which can help preserve or increase
employment in those sectors. However, higher import costs may raise prices of intermediate goods, increasing
production costs and potentially reducing employment in industries reliant on imports.

c. Infant Industry:
Trade restrictions provide temporary protection to nascent domestic industries, allowing them time to develop
competitiveness without being overwhelmed by established foreign firms. This protection can enable infant
industries to grow and eventually compete globally.

d. Income Distribution:
Trade restrictions can affect income distribution by benefiting workers and owners in protected industries while
harming consumers who face higher prices. Often, capital owners and skilled workers gain, while unskilled
workers and consumers may lose, potentially increasing income inequality.

In summary, trade restrictions can protect domestic interests but may cause inefficiencies, higher prices, and
uneven income effects within the importing country.
