He has published articles and papers in different newspapers and journals, and collaborates in the New York Times on a regular basis. It is thanks to Krugman’s communication abilities and his numerous publications, that he has become an international reference.
Krugman is best known for his research on international trade. He was awarded the Nobel Prize in Economics Sciences in 2008 for his work regarding the interpretation of patterns of international trade. He has broadened the general understanding of economic phenomena such as trade and the location of economic activities. In his paper “Increasing Returns, Monopolistic Competition, and International Trade”, 1978, Krugman sustains that trends and arrangements of international trade, and also the geographic congregation of wealth, can be explained by economies of scale and by consumer’s preferences for goods and services.
