Review Questions

• How does Paul Krugman's new trade theory expand on the concept of comparative advantage?
  • Paul Krugman's new trade theory expands on comparative advantage by incorporating factors such as economies of scale and market imperfections. While traditional comparative advantage focuses on differences in opportunity costs between countries, Krugman's approach highlights how larger firms can benefit from reduced costs through increased production. This leads to a more complex understanding of why countries may specialize in certain industries and engage in trade, even when they don't have a clear comparative advantage.
• Evaluate the implications of Krugman's theories on globalization for developing economies.
  • Krugman's theories on globalization suggest that while it offers opportunities for developing economies to engage in international trade, it also presents challenges such as increased competition from established markets. Developing countries may find it difficult to compete with larger firms that benefit from economies of scale. However, by focusing on niche markets or specific industries where they can build competitive advantages, these economies can leverage globalization to foster growth. Understanding these dynamics is crucial for policymakers aiming to harness the benefits while mitigating risks associated with global economic integration.
• Synthesize Krugman's insights on fiscal policy with his views on international trade in order to propose a holistic approach for managing an economy in crisis.
  • To manage an economy in crisis effectively, one can synthesize Paul Krugman's insights on fiscal policy with his perspectives on international trade by advocating for coordinated government intervention and strategic engagement in global markets. Krugman emphasizes the necessity of fiscal stimulus during downturns to support domestic demand and prevent deep recessions. Simultaneously, he acknowledges the role of globalization in shaping competitive industries. A holistic approach would involve implementing robust fiscal policies that not only stimulate local economies but also support sectors poised for growth in international markets, ensuring long-term resilience against global economic fluctuations.
