Explain the conditions under which complete specialisation will be possible for two nations in case of comparative advantage. Suppose productivity per unit of labour for two nations, India and UK, is given as under:

How to Approach

This question requires an understanding of the theory of comparative advantage and its implications for international trade. The approach should involve first defining comparative advantage and complete specialization. Then, calculate the opportunity costs for both India and the UK for each good. Finally, based on these opportunity costs, determine the conditions under which complete specialization would be possible, demonstrating how each nation would benefit from focusing on its comparative advantage. The answer should be structured logically, with clear explanations and calculations.

Introduction

The theory of comparative advantage, first articulated by David Ricardo in 1817, forms the cornerstone of international trade economics. It posits that nations benefit from specializing in the production of goods and services they can produce at a lower opportunity cost, even if they don't possess an absolute advantage in their production. Complete specialization occurs when a nation dedicates all its resources to producing only one good or service, and then trades for others. This question asks us to analyze the conditions under which complete specialization is feasible for India and the UK, given their respective labour productivities.

Understanding Comparative Advantage and Opportunity Cost

Before analyzing the given scenario, it’s crucial to understand the concepts of comparative advantage and opportunity cost. Opportunity cost represents the value of the next best alternative foregone. In the context of production, it’s the amount of one good that must be sacrificed to produce one additional unit of another good.

Productivity Data and Opportunity Cost Calculation

Let's analyze the productivity data provided for India and the UK:

Nation Wheat (Units of Labour per Unit) Cloth (Units of Labour per Unit)
India 10 20
UK 1 2

Now, let's calculate the opportunity costs:

India’s Opportunity Costs:

  • Opportunity cost of 1 unit of Wheat = 20/10 = 2 units of Cloth
  • Opportunity cost of 1 unit of Cloth = 10/20 = 0.5 units of Wheat

UK’s Opportunity Costs:

  • Opportunity cost of 1 unit of Wheat = 2/1 = 2 units of Cloth
  • Opportunity cost of 1 unit of Cloth = 1/2 = 0.5 units of Wheat

Conditions for Complete Specialization

Complete specialization will be possible if each nation focuses on producing the good for which it has a lower opportunity cost. In this case:

  • India has a comparative advantage in Cloth because its opportunity cost of producing Cloth (0.5 units of Wheat) is lower than the UK’s (0.5 units of Wheat).
  • The UK has a comparative advantage in Wheat because its opportunity cost of producing Wheat (2 units of Cloth) is lower than India’s (2 units of Cloth).

Therefore, complete specialization will occur if:

  • India dedicates all its labour resources to producing Cloth.
  • The UK dedicates all its labour resources to producing Wheat.

Benefits of Specialization and Trade

When India specializes in Cloth and the UK in Wheat, and they engage in trade, both nations can consume beyond their production possibilities frontier. For example, if India produces only Cloth, it can produce 1 unit of Cloth with 20 units of labour. If it trades this for Wheat from the UK, it can obtain more Wheat than it could have produced domestically. Similarly, the UK can obtain more Cloth through trade than it could have produced domestically.

Role of Trade Terms

The actual terms of trade (the ratio at which goods are exchanged) will determine the extent of gains from specialization. The terms of trade must lie between the opportunity costs of both countries for mutually beneficial trade to occur. In this case, the terms of trade must be between 0.5 and 2 units of Wheat for 1 unit of Cloth.

Limitations and Real-World Considerations

While the model demonstrates the benefits of specialization, several real-world factors can hinder complete specialization. These include:

  • Transportation costs: High transportation costs can reduce the gains from trade.
  • Trade barriers: Tariffs and quotas can restrict trade and prevent specialization.
  • Demand conditions: Changes in demand can alter the optimal level of specialization.
  • Diversification: Nations may choose to diversify their production for strategic or economic security reasons.

Conclusion

In conclusion, complete specialization for India and the UK is possible based on comparative advantage, with India specializing in Cloth and the UK in Wheat. This specialization leads to increased production efficiency and allows both nations to benefit from trade by consuming beyond their individual production possibilities. However, real-world factors like transportation costs and trade barriers can influence the extent to which complete specialization is achieved. The theory of comparative advantage remains a fundamental principle guiding international trade policies and economic analysis.

Examples

Bangladesh and Garment Industry

Bangladesh has specialized in the garment industry due to its low labour costs, gaining a comparative advantage in this sector and becoming a major exporter of ready-made garments.

Frequently Asked Questions

What happens if a country doesn't have a comparative advantage in any good?

Even a country without an absolute or comparative advantage in any particular good can benefit from trade by specializing in the production of goods where its disadvantage is least pronounced and trading for others. Trade allows access to a wider variety of goods and services at lower costs.
