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 maximising accumulation in his own sector. Their plans are based on available quantities and expected prices. Effective prices...

We build a bisector reproduction model with classical features in which the capitalists aim at maximizing accumulation of their profits. At variance with gravitation models, it is assumed that they invest their profits in their own industry. Their plans are based on actual productions and...

The parametric Lemke algorithm is used to show the existence of an odd number of solutions of a generalized bimatrix game in a certain domain. These solutions are classi?ed into two types according to the relative sign of two determinants. The British economist David Ricardo made an implicit use...

The Ricardian dynamics study the evolution of distribution when demand increases. The successive marginal methods in agriculture are determined by means of a rule which has never been stated explicitly by Ricardo's commentators. But the rule also allows us to point at two limits of Ricardo's...

The parametric Lemke algorithm finds an odd number of solutions to the linear complementarity problem LCP (q, M), for a matrix M with zero blocks on the diagonal and vector q within a certain domain. A criterion for monotonicity and uniqueness is given. The algorithm applies to the determination...

In order to extend the theory of value and the trade-off property to economic systems with lands, Ricardo reduced their study to that of productive systems without lands by considering the marginal agricultural methods. Sraffa generalised the analysis to prices of production and rejected the...

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...

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...

We generalize the concept of industry, which stems from the analysis of single-product economies, to that of sector. The sector concept can be applied to economies with or without joint-product processes and pure capital goods. A ‘sectoral economy’ is an economy characterized by the...

Maurice Potron (1872-1942) is a French Jesuit and mathematician whose main source of inspiration in economics is the encyclical Rerum Novarum. With virtually no knowledge in economic theory, he wrote down a linear model of production in which he formalized the notions of just prices and just...
