For an increasing upper order hemi-continuous correspondence F selfmapping sigma-complete lattice A, we first provide tight fixed-point bounds for sufficiently large iterations on F starting from any initial point a in A. We use this result for conducting iterative fixed-point comparative...

There are three types of "Anything Goes" results: two of them from economic theory and one from the realms of dynamical systems. The study considers the implications of such results and tries to identify conditions under which certain types of conclusions may be implied: convergence, cycles or...

Competition between oligopolist electricity generators is inhibited by transmission constraints. I present a supply function equilibrium (SFE) model of an electricity market with a single lossless, but constrained, transmission line. The market admits equilibria in which generator withhold...

This article presents a new approach to analyze the equilibrium set of symmetric, differentiable games by separating multiple symmetric equilibria and asymmetric equilibria. This separation allows the investigation of, for example, how various parameter constellations affect the scope for...

Under certain conditions on the excess demand function, it is shown that the set of equilibrium prices coincides with the set of maximizers of a potential function. Therefore, monotone comparative statics techniques can be employed to study how equilibrium prices change when there are shocks to...

We consider a class of stochastic discounted games with increasing preferences. We first prove existence of extremal Stationary Markov Perfect Equilibria (SMPE) in pure strategies, and we characterize those equilibria as unique fixed points of well-chosen operators. We use this characterization...

Purpose - The purpose of this paper is to study the Hölder calmness of solutions to equilibrium problems and apply it to economics. Design/methodology/approach - The authors obtain the Hölder calmness by using an effective approach. More precisely, under the key assumption of strong convexity,...

This paper studies an economy whose agents perceive their consumption possibilities subjectively, and whose preferences are defined on what they subjectively experience, rather than on those alternatives that are objectively present. The model of agents' perceptions is based on intuitionistic...

We study the equilibrium existence problem in normal form and qualitative games in which it is possible to associate with each nonequilibrium point an open neighborhood and a collection of deviation strategies such that, at any nonequilibrium point of the neighborhood, a player can increase her...
