[eng] The relationships between the classical and neoclassical theories are much more complex that the neo-Ricardians use to recognize. Sraffa's study is indeed a clever criticism fo some ancient versions of the marginalist theory, such as those developed by Bo'hm-Bawerk or J.B. Clark, but it...

[fre] Quelques difficultés liées à la définition et aux propriétés des systèmes non fondamentaux dans l'œuvre de Sraffa. [eng] Some difficulties connected with the definition and properties of non-basic systems in Sraffa's work.

We fully characterise, in terms of their local or global properties, the wage curves associated with Austrian models of production. When these properties are met, the degrees of freedom in the choice of parameters allow us to build an Austrian model which admits a given wage curve and satis…es...

Maurice Potron (1872-1942) is a French Jesuit and a talented mathematician. A recent rediscovery of his economic model, which was left unnoticed in his times, lets Potron appear as a pioneer, both for the framework he conceived and the mathematical methods he used. Moreover, there are hints that...

We consider a bisector reproduction model in which money is introduced as a pure means of exchange issued by a bank at the producers' requests. Each capitalist aims at maximizing accumulation in his own sector. Their plans are based on available quantities and expected prices. Effective prices...

We propose to re-read Ricardo's theory of rent and its modern versions. Ricardo's dynamic approach follows the transformations of a long-term equilibrium with demand. Sraffa adopted the same framework while substituting a value criterion for a physical criterion to determine the incoming...

Long-term prices depend on distribution in a complex way, especially when choice of technique is allowed. It is shown, however, that the movement of prices in terms of wage obeys certain laws. More precisely, the movement is characterized in terms of linear programming problems. Necessary or...

It is shown that relative prices of production, which depend on the rate of profit in a complicated manner, satisfy nevertheless a simple monotonicity law when the Hilbert's projective metric is used as a measure. <!--ID="" Correspondence to: U. Krause-->
