Review Questions

• How does David Ricardo's theory of comparative advantage explain the benefits of international trade between countries?
  • David Ricardo's theory of comparative advantage shows that countries can gain from trade by specializing in goods they produce most efficiently relative to others. Even if one country is less efficient in producing all products, it can still benefit by focusing on areas where it has a lower opportunity cost. This specialization allows countries to trade for goods they are less efficient at producing, resulting in overall economic gains for all parties involved.
• What role did David Ricardo's work play in shaping modern economic thought regarding international trade?
  • David Ricardo's work significantly influenced modern economic thought by establishing the principles of comparative advantage, which became a core concept in trade theory. His insights emphasized how trade could enhance global wealth by allowing countries to specialize based on their efficiencies. This laid the groundwork for understanding the complexities of global markets and how they function, impacting subsequent theories and policies in international economics.
• Evaluate the implications of Ricardo's theories on contemporary debates surrounding globalization and protectionism.
  • Ricardo's theories highlight the benefits of globalization by illustrating how countries can achieve greater efficiency and wealth through trade based on comparative advantages. However, contemporary debates about globalization often involve concerns over job losses and income inequality within nations. These discussions reflect Ricardo's insights into income distribution effects, prompting policymakers to consider balancing free trade with protective measures to support vulnerable industries while still harnessing the advantages of international commerce.
