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...

In this note we discuss two examples of approval voting games.

Voting games are characterized by the emergence of dominated strategies, that would be iteratively deleted by rational players. In this note we show, via an example, how applying iterated dominance retricts the set of equilibrium outcomes in Besley and Coate (1997) citizen-candidate model of...

In this paper we study the concepts of equilibrium and optimum in static transportation networks with elastic and non-elastic demands. The main mathematical tool of our paper is the theory of variational inequalities. We demonstrate that this theory is useful for proving the existence theorems....

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 that for generic (non cooperative) voting games under plurality rule an equilibrium that induces a mixed distribution over the outcomes (i.e. with two or more candidates elected with positive probability) is isolated. From that we deduce also that the set of equilibrium...

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....

We model the decision problems faced by the members of societies whose new members are determined by vote. We adopt a number of simplifying assumptions. In spite of these simplifications, we show that interesting strategic behavior is implied by the dynamic structure of the problem: the vote for...

Within this framework of pure redistriubtion (dividing one unit of a homogeneous good among identical individuals), the paper analyses the redistributions that arise from Downsian two-party electoral competition. It appears that the strategic behavior of vote-maximizing parties lead them to...

In this paper we consider a labor constrained scheduling problem (LCSP) which is a simplification of a practical problem arising in industry. Jobs are subject to precedence constraints and have specified processing times. Moreover, for each job the labor requirements varies as the job is...
