Michael Hogan shows how The Marshall Plan was more than an effort to put American aid behind the economic reconstruction of Europe. American officials hoped to refashion Western Europe into a smaller version of the integrated single-market and mixed capitalist economy that existed in the United States. Professor Hogan's emphasis on integration is part of a major reinterpretation that sees the Marshall Plan as an extension of American domestic and foreign-policy developments stretching back through the interwar period to the Progressive Era. Michael Hogan is Professor of History at Ohio State University and editor of Diplomatic History.
