In this paper the existence of unemployment is partly explaines as being the result of coordination failures. This is achieved by considering a standard general equilibrium modes and splitting the set of commodities in two groups. The first group contains commodities like gold. The prices of...

This is a study in the field of unemployment and unemployability. I build an unclosed matching model of unemployment, where matching rates are exogenous. The value of an unfilled job depends on the average skill of the unemployed, who are supposed to lose (absolutely, or relatively) some of...

Prime objects of this note are (I) excess demand generated by price-taking economic agents, and (II) an alternative version of tatonnement. We relate laws of demand, axioms of revealed preferences, and other notions of generalized monotonicity to evolutionary stable prices. Focus is on local...

We incorporate a renewable resource into an overlapping generations model with standard, well-behaved utility and constant returns to scale production functions. Besides being a factor of production the resource serves as a store of value. We characterize dynamics, efficiency and stability of...

Given a compact connected component of zeros of a vector field, we give a necessary condition for its asymptotic stability in terms of its index and Euler characteristic.

In this paper, we prove an existence theorem for equilibria in production economies with increasing returns, which generalizes the classis results on this topic. In partular, we eliminate both the free-disposal assumptions and any smoothness requirements on the boundary of the production sets....

This paper introduces, within a general equilibrium setting, an alternate theory of value that provides a value-based characterization of the most important notions of allocative equilibria even in cases where the (Walrasian) uniform price-based characterizations need not be applicable. The...

In contrast to the neo-classical theory of Arrow and Debreu, a model of a private ownership economy is presented, in which production and consumption bundles are treated separately. Each of the two types of bundles is assumed to establish a convex cone. Production technologies can convert...

We study the polytopes of binary n-strings that encode (positive) integers that are not divisible by a partivular positive integer p - the indivisibility polytopes, as well as the more general "clipped cubes". Also, we discuss a potential application to factoring. Finally, we present some...

This paper shows that Barro's (1974) debt neutrliaty theorem does not hold in OLG economies whenever the marginal rate of substitution between both periods' consumptions evaluated at the modified golden rule capital stock is lower that the degree of intergenerational altruism. It could be...
