Joan Robinson et la théorie économique

L’auteur examine l’oeuvre scientifique de Joan Robinson dans cinq domaines où ses contributions furent notables : (1) l’analyse de la concurrence imparfaite, (2) la théorie de l’emploi, (3) la théorie de l’accumulation à long terme, (4) la notion de capital et la fonction de production, et (5) le traitement du temps en économique, tel que reflété dans ses travaux sur l’histoire et l’équilibre.This essay examines Joan Robinson's writings in five areas where her scientific contributions were significant: (1) the economics of imperfect competition, (2) the theory of employment, (3) the theory of accumulation in the long run, (4) the concept of capital and the production function, and (5) the treatment of time in economics as reflected in her writings on the theme of history versus equilibrium

Keynes et Sraffa

Keynes' General Theory of Employment, Interest and Money and Sraffa's Production of Commodities by Means of Commodities were concerned with different problems, and this is reflected in the structure of the models they used. Keynes was concerned with the factors determining the level of employment in a particular period of time — a short period — and the ways in which that level of employment could be thanged over a sequence of these short periods. There is great scope for disappointment of expectations and uncertainty in his analysis — it is not tied in any way to long-period equilibrium. Sraffa's analysis was concerned with highly abstract theoretical questions — the value nature of capital and the lack of logical foundations for any marginal productivity theory of distribution that treats aggregate capital as an input. For this purpose, an analysis solely concerned with long-period equilibrium situations is not inappropriate. In these works there is no meeting ground between Sraffa and Keynes. The joining of the two analyses — except as a very special case in which entrepreneurial investment-expectations turned out to be validated by events — would distort seriously the nature of Keynes' analysis
