Review Questions

• Explain how David Ricardo's theory of comparative advantage relates to the concept of trade deficits and surpluses.
  • According to Ricardo's theory of comparative advantage, countries should specialize in the production of goods they can produce most efficiently and trade for other goods. This specialization can lead to trade deficits or surpluses, as countries may import more of certain goods than they export. However, Ricardo argued that these trade imbalances are not necessarily harmful and can be beneficial for countries in the long run, as they allow countries to take advantage of their comparative advantages and engage in mutually beneficial trade.
• Describe how David Ricardo's ideas on trade and wages, known as the 'Ricardo effect,' relate to the difference between the level of trade and the trade balance.
  • The 'Ricardo effect' refers to Ricardo's analysis of the relationship between trade and wages. He argued that trade can lead to a redistribution of income, with some workers benefiting from higher wages while others may face lower wages. This effect is distinct from the overall level of trade, which may be high even if the trade balance is in deficit or surplus. The difference between the level of trade and the trade balance is an important consideration in understanding the broader economic impacts of trade, as the distribution of gains and losses from trade can have significant implications for domestic policies and political dynamics.
• Evaluate the lasting influence of David Ricardo's theories on absolute and comparative advantage, and how they have shaped modern international trade policies and agreements.
  • David Ricardo's theories on absolute and comparative advantage have had a profound and lasting impact on the field of international trade. His ideas have formed the foundation for modern trade policies and the development of international trade agreements, such as the World Trade Organization (WTO). Ricardo's emphasis on the benefits of specialization and trade, even in the absence of absolute advantage, has influenced the design of trade agreements that aim to promote mutually beneficial exchange between countries. Furthermore, Ricardo's insights on the distributional effects of trade, as captured in the 'Ricardo effect,' continue to shape debates around the impacts of globalization and trade liberalization. Overall, Ricardo's pioneering work has been instrumental in shaping our understanding of the complex dynamics of international trade and its implications for economic development and social welfare.
