The paper distinguishes between two routes along which orthodox theory can be criticized in order to establish the principle that aggregate demand may be insufficient to absorb the output obtainable from normal utilization of existing productive capacity. Keynes based himself on the obstacles which liquidity preference raises for the adaptation of the interest rate to changes in the incentive to invest. Another route has however been opened up by the critique of the orthodox notion of a «quantity» of.capitai which showed that there is no reason to assume a regular inverse relation between investment and the interest rate allowing the latter, even if flexible, to adjust investment to full employment savings. This second route deprives of its basis the neo-classical synthesis's attempt to confine «effective demand» to short period fluctuations and sets the ground for an analysis of its influence on accumulation.

Au sein de la riche littérature issue du cadre élaboré par Sraffa dans Production of Commodities by Means of Commodities , une position éminente est occupée par les programmes de recherche développés de façon indépendante par deux représentants de cette école qui font référence : Pierangelo Garegnani et Luigi Pasinetti. Certains aspects spécifiques de leurs approches pourraient donner à penser qu'elles sont alternatives. Cependant, quand on les analyse dans une perspective constructive, on découvre non seulement une origine et une méthodologie communes, mais aussi une stricte complémentarité dans l'analyse des principales caractéristiques des systèmes industriels.
