Like all great intellectual pioneers, Wassily Leontief has inspired a new generation of researchers. This collection contains key articles that critically assess Leontief's contribution to economics, as well as a number of articles that build on his economic theories. The set is designed to enable historians of economic thought to discern Leontief's specific contribution to the discipline, without losing sight of the interdependence between the various aspects of his work. To facilitate this, articles have been reproduced on a thematic basis. Articles have been selected by their importance for historians of economic thought, contemporary economists and policy makers, providing a comprehensive overview of the English language assessment of Leontief's legacy to economic science.
