This volume focuses on the importance of the history of economic thought as an intellectual discipline. It counters the arguments of some contemporary economists who describe it as studying the mistakes of the past. However, all the great economists - Smith, Ricardo, Marx, Marshall, Keynes and even Milton Friedman - have drawn on the history of economics to find an appropriate pedigree for their own theoretical innovations. This important volume contains high quality articles - written from different perspectives - demonstrating the importance of the history of economic thought.
