To honor the life work of Professor Sumner Rosen, this lecture examines approaches to promoting full employment at decent jobs within our contemporary era of globalization. The lecture briefly summarizes the theories of unemployment of Marx, Friedman, Keynes and Kalecki. It then addresses the meaning of full employment within the alternative theories and under different historical and country settings. It next considers the issue of the inflation/unemployment trade-off, and the Meidner-Rehn Swedish approach to inflation control under full employment. It concludes by presenting a sketch of something approximating a full employment program for the contemporary U.S. economy, focusing on ending the Iraq war and reallocation public spending toward health care, education, and green growth.
