Economics Comparative Advantage Questions Long
The theory of comparative advantage is based on several key assumptions. These assumptions are essential for understanding and applying the theory in the field of economics. The assumptions underlying the theory of comparative advantage are as follows:
1. Two countries and two goods: The theory assumes that there are only two countries involved in trade and that each country produces two different goods. This simplification allows for a clear analysis of the concept of comparative advantage.
2. Constant costs: The theory assumes that the costs of production remain constant in both countries. This means that the resources used to produce goods do not change in terms of their efficiency or productivity over time.
3. Full employment: The theory assumes that both countries are operating at full employment, meaning that all available resources are being utilized efficiently. This assumption ensures that the focus is solely on the differences in productivity and efficiency between countries.
4. No transportation costs or trade barriers: The theory assumes that there are no transportation costs or trade barriers between the two countries. This assumption allows for the free flow of goods between countries, enabling specialization and trade based on comparative advantage.
5. Perfect competition: The theory assumes that markets are perfectly competitive, meaning that there are many buyers and sellers, and no single entity has the power to influence prices. This assumption ensures that prices accurately reflect the underlying costs and productivity differences between countries.
6. Constant returns to scale: The theory assumes that there are constant returns to scale, meaning that increasing the scale of production does not lead to a significant change in costs. This assumption allows for a straightforward comparison of production efficiencies between countries.
7. Rational decision-making: The theory assumes that individuals and firms act rationally, seeking to maximize their own self-interest. This assumption implies that countries will specialize in producing goods in which they have a comparative advantage, as it will lead to higher profits and economic welfare.
These assumptions provide the foundation for the theory of comparative advantage and help to explain why countries engage in trade based on their relative efficiencies and productivity levels. While these assumptions may not always hold true in the real world, they serve as a useful framework for understanding the benefits of specialization and trade between countries.
