A general equilibrium technique is used to show the existence of a solution to a nonlinear complementarity problem involving a copositive function.

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 Ricardian dynamics describe the substitution of a new marginal method for an outgoing marginal method when demand increases. The process of extension or intensi…cation of cultivation allows for spasmodic changes in prices and rents but is smooth on the physical side. We criticize the notion...

If land is uniform in quality, an increase in the demand for agricultural goods leads to the use of more intensive cultivation methods. Though Ricardo saw no difficulties in the intensification process, their existence is revealed by the possible occurrence of multiple equilibria. A general...
