"In this age of specialization, I sometimes think of myself as the last 'generalist' in economics," wrote Paul Anthony Samuelson, Professor of Economics at the Massachusetts Institute of Technology, "with interests that range from mathematical economics down to current financial journalism. My real interests are research and teaching... " His work in economic theory has been in modern welfare economics, linear programming, Keynesian economics, economic dynamics, international trade theory, logic choice and maximization. In terms of economic philosophy, Professor Samuelson calls himself "a 'modern' economist... in the right wing of the Democratic New Deal economists."
