Theories of International Trade MCQs with Answers

Use this page to revise absolute advantage, comparative advantage, opportunity cost, factor endowment, and trade logic in a clean exam-oriented format. The explanations open after submission so students can check both accuracy and concept clarity in one attempt.

Quick revision before you attempt the test

This unit becomes easy once students separate theory names clearly, link each theory to its core logic, and avoid mixing productivity with opportunity cost.

Absolute vs comparative advantage Absolute advantage is about higher productivity. Comparative advantage is about lower opportunity cost. This is the most common ICAI trap area.
Ricardo theory logic Even if one country has no absolute advantage, trade can still happen if comparative cost differs. This is the backbone of international trade theory.
Heckscher-Ohlin theory Countries export goods that use their abundant factor intensively. Labour-abundant countries export labour-intensive goods. Capital-abundant countries export capital-intensive goods.

Common traps students confuse

Productivity vs opportunity cost Adam Smith focuses on productivity under absolute advantage. Ricardo focuses on relative sacrifice under comparative advantage.
Labour intensive vs capital intensive Labour-intensive goods use relatively more labour. Capital-intensive goods use relatively more capital.
Free trade vs protectionism Free trade reduces restrictions. Protectionism uses tools like tariffs and other barriers to restrict trade.
Core theories and basic trade concepts
Question 01
International trade means:
International trade means exchange of goods and services between different countries, not within one domestic economy.
Question 02
Absolute advantage theory is given by:
Adam Smith gave the theory of absolute advantage to explain why countries gain by specialising where they are more productive.
Question 03
Comparative advantage theory is given by:
David Ricardo explained that trade can arise even when one country is more efficient in all goods, because relative cost still differs.
Question 04
Absolute advantage means:
Absolute advantage refers to higher productivity or lower real resource use in producing a good compared with another country.
Question 05
Comparative advantage means:
Comparative advantage depends on lower opportunity cost, not necessarily on being absolutely more productive.
Question 06
Trade benefits arise due to:
International trade becomes beneficial because countries differ in resources, technology, skills, or relative production costs.
Question 07
Specialisation means:
Specialisation means concentrating more on the good in which a country is relatively more efficient.
Question 08
Gains from trade arise due to:
The core source of gains from trade in theory is comparative advantage.
Question 09
Opportunity cost refers to:
Opportunity cost is the sacrifice of the next best alternative when a choice is made.
Question 10
Ricardo model assumes:
The simple Ricardian model usually assumes two countries, two goods, and one factor of production.
Question 11
Labour is:
In the basic Ricardian model, labour is treated as the only factor of production.
Question 12
Trade leads to:
Voluntary international trade generally creates mutual gains because both countries can consume beyond autarky possibilities.
Question 13
Heckscher-Ohlin theory is based on:
The Heckscher-Ohlin theory explains trade through differences in factor endowments across countries.
Question 14
Factor endowment means:
Factor endowment means the relative availability of productive resources like labour, capital, and land.
Question 15
Capital abundant country exports:
According to the H-O theory, a capital-abundant country tends to export capital-intensive goods.
Question 16
Labour abundant country exports:
A labour-abundant country tends to specialise in and export labour-intensive goods.
Question 17
Trade increases:
Trade can raise efficiency, output, and welfare together, so the correct choice is all of these.
Application, trade policy, and theory logic
Question 18
Absolute advantage focuses on:
Absolute advantage compares productivity levels across countries, not relative sacrifice.
Question 19
Comparative advantage focuses on:
Comparative advantage is judged by lower opportunity cost.
Question 20
A country without absolute advantage can still trade due to:
Ricardo showed that lack of absolute advantage does not block trade if comparative cost differs.
Question 21
Ricardo theory ignores:
A standard limitation of the Ricardian model is that it ignores transport cost and several real-world frictions.
Question 22
Constant cost assumption means:
Constant cost means opportunity cost remains fixed as production shifts from one good to another.
Question 23
Heckscher-Ohlin assumes:
The basic H-O model works with two factors of production, usually labour and capital.
Question 24
Capital intensive goods require:
Capital-intensive goods use relatively more capital than labour in production.
Question 25
Labour intensive goods require:
Labour-intensive goods require relatively more labour input.
Question 26
Factor price equalisation means:
The factor price equalisation idea says trade tends to narrow international differences in factor rewards such as wages and returns to capital.
Question 27
Trade leads to:
Trade encourages countries to allocate resources more efficiently according to comparative advantage.
Question 28
Terms of trade refers to:
Terms of trade means the ratio of export prices to import prices.
Question 29
Improvement in terms of trade means:
An improvement in terms of trade means a country gets more imports for a given quantity of exports.
Question 30
Trade restriction includes:
A tariff is a direct form of trade restriction.
Question 31
Free trade means:
Free trade means international exchange with minimal or no artificial restrictions.
Question 32
Protectionism means:
Protectionism means policies that restrict trade to protect domestic producers.
Question 33
Export leads to:
Exports create production, employment, and income generation in the domestic economy.
Question 34
Import leads to:
Imports increase availability of goods and widen consumer and producer choices.
Advanced concepts and exam trap areas
Question 35
Comparative advantage exists when:
Comparative advantage exists when a country can produce a good at lower opportunity cost than another country.
Question 36
Gains from trade depend on:
The central explanation of gains from trade is comparative advantage.
Question 37
Ricardo theory limitation:
A major limitation of Ricardo's theory is its one-factor assumption.
Question 38
Heckscher-Ohlin explains trade based on:
The H-O model explains trade through relative factor abundance or factor endowment.
Question 39
Capital abundant country has:
A capital-abundant country has a relatively larger supply of capital compared with labour.
Question 40
Labour abundant country has:
A labour-abundant country has a relatively larger supply of labour.
Question 41
Trade increases welfare through:
Trade improves welfare through specialisation, exchange, and efficiency gains together.
Question 42
Opportunity cost determines:
In comparative advantage theory, opportunity cost determines the pattern of specialisation and trade.
Question 43
In absence of trade:
Without trade, a country can consume only what it produces domestically, so consumption remains limited.
Question 44
Terms of trade improvement benefits:
When terms of trade improve, the exporter gains because its exports command more imports.
Question 45
Protectionism leads to:
Protectionism can protect domestic producers, but it often leads to inefficiency and resource misallocation.
Question 46
Free trade leads to:
Free trade generally improves efficiency by directing production toward comparative advantage.
Question 47
Gains from trade are:
The standard theory says gains from trade are mutual, though their size may differ.
Question 48
Heckscher-Ohlin model assumes:
The basic H-O model assumes countries share the same technology and differ mainly in factor endowments.
Question 49
Trade pattern depends on:
In the H-O framework, trade pattern depends mainly on factor endowment.
Question 50
Comparative advantage leads to:
Comparative advantage pushes countries toward specialisation in the good they produce relatively more cheaply.

Why this MCQ page matters

Theories of International Trade MCQs with answers for focused CA Foundation revision.

This page is useful after theory revision because it helps students separate Adam Smith, Ricardo, and Heckscher-Ohlin clearly without mixing up productivity, opportunity cost, and factor endowment in objective questions.

  • Chapter-wise practice for International Trade and Indian Economy
  • Instant checking with explanations after submission
  • Useful for revision, class tests, and self-practice
  • Best used after reading the notes for this unit
Better practice flow

Revise theory comparison first, then attempt the MCQs, then revisit only weak areas.

Students usually improve faster when they first lock absolute advantage, comparative advantage, and factor endowment logic, then attempt the paper, and finally recheck only the mistakes instead of revising the full unit again.

Focus areas for re-revision

  • Absolute advantage vs comparative advantage
  • Opportunity cost and specialisation logic
  • Heckscher-Ohlin and factor endowment
