Review Questions

• How does Paul Krugman's New Trade Theory redefine traditional concepts of comparative advantage?
  • Krugman's New Trade Theory challenges traditional views by arguing that even if a country does not have a comparative advantage in producing a good, it can still benefit from trade by specializing in certain sectors due to economies of scale. This means that as production increases, the average cost per unit decreases, allowing countries to leverage their size or technology. This shift helps explain why some industries cluster in specific regions despite apparent disadvantages.
• Discuss the role of agglomeration economies in Krugman's economic geography framework.
  • In Krugman's framework, agglomeration economies play a crucial role by illustrating how firms benefit from being located near one another. This proximity allows businesses to share resources, labor pools, and knowledge, enhancing productivity and fostering innovation. As industries cluster geographically, they create a competitive advantage that further attracts firms and talent to the area, reinforcing regional economic growth.
