Principle of Comparative Cost Advantage And Its Limitations - SS3 Economics Lesson Note

The principle of comparative cost advantage proposes that countries can benefit from specializing in the production of goods and services that they can produce at a lower opportunity cost compared to other countries. In other words, a country should produce and export goods that it can produce relatively more efficiently than other countries, and import goods that other countries can produce more efficiently.

For example, if Country A can produce wheat more efficiently than Country B, while Country B can produce textiles more efficiently than Country A, then it makes sense for Country A to specialize in producing wheat and export it to Country B, while Country B specializes in producing textiles and export it to Country A.

The principle of comparative cost advantage has several benefits. It enables countries to produce more goods and services at lower costs, leading to increased productivity and economic growth. It also allows countries to access a wider variety of goods and services that they may not be able to produce domestically.

Limitations of Comparative cost advantage

There are also some limitations to the principle of comparative cost advantage. Firstly, it assumes that resources are freely mobile between different sectors within a country. This may not always be the case, as factors such as labour immobility or infrastructure limitations may prevent a country from shifting resources from one sector to another.

Additionally, the principle assumes that countries have similar production technologies, while in reality, the level of technology differs from country to country. Differences in technology and infrastructure can result in significant disparities in production costs between countries, which can affect the viability of comparative cost advantage.

Lastly, comparative cost advantage may lead to unequal distribution of gains, where one country benefits more from trade than another. This can lead to political tensions and trade disputes between countries.
