Des travaux de Wassily Leontief, on retient surtout ses tableaux entrées-sorties (TES), les célèbres TES de la comptabilité nationale, en oubliant l'ambition scientifique au service de laquelle ils avaient été conçus. Développé à Harvard dans les années 1930, le TES est un élément dans un dispositif scientifique visant à faire de l'économie une science empirique. Il est une matrice comptable associée à un modèle mathématique de l'équilibre économique général. Ce dispositif est conçu comme une alternative à l'économétrie que Leontief considère mal équipée pour résoudre le problème de l'association de la théorie à la mesure statistique. C'est qu'en économie, selon l'expression d'Alain Desrosières, le mariage entre la théorie et les statistiques est tardif et que le branchement ne va pas de soi. Cet essai présente d'abord la méthodologie économique de Leontief et montre comment elle s'insère dans les grands débats épistémologiques de la discipline jusqu'à aujourd'hui. L'ouvrage propose ensuite une réédition de l'article de Leontief « Les mathématiques et la science économique » (1954). In Europe, Wassily Leontief is remembered mainly for his input-output tables, which are considered a useful tool for national accounting. However, the scientific project which led to the development of IOTs has been ignored. IOTs were developed by Leontief at Harvard in the 1930s, as a component of a scientific scheme designed to make economics a genuine empirical science. IOTs were, indeed, conceived as an accounting matrix twinned with a mathematical model of general economic equilibrium. The scheme was designed as an alternative to econometrics, as Leontief considered the latter ill-equipped to link economic theory with statistical measurement. As Alain Desrosières once stated, in economics, the "marriage" between economic theory and statistics was slow to emerge and the connection was not straightforward.

Wassily Leontief (1905-1999) was the founding father of input-output economics, for which he received the Nobel Prize in 1973. This book offers a collection of papers in memory of Leontief by his students and close colleagues. The first part, 'Reflections on Input-Output Economics', focuses upon Leontief as a person and scholar as well as his personal contributions to economics. It includes contributions by Nobel Laureate Paul A. Samuelson who shares his memories of a young Professor Leontief at Harvard and ends with the last joint interview with Wassily and his wife, to date previously unpublished. The second part, 'Perspectives of Input-Output Economics', includes theoretical and empirical research inspired by Leontief's work and offers a wide-ranging sample of the state of interindustry economics, a field Leontief founded. This is a strong collection likely to appeal to a wide range of professionals in universities, government, industry and international organizations.
