Krugman’s work in international trade theory has significantly advanced our understanding of the dynamics of global trade. He expanded upon David Ricardo’s theory of comparative advantage by introducing new trade theory, which considers factors beyond comparative advantage, such as economies of scale and imperfect competition. Krugman’s research demonstrated that economies of scale can lead to the concentration of industries in specific regions, creating clusters of economic activity.
His theories have had a profound impact on global trade policies, challenging traditional notions of trade patterns and advocating for policies that promote regional specialization.
