Computing integral solutions of complementarity problems
Laan, Gerard van der; Talman, Dolf; Yang, Zaifu - 2004
In this paper an algorithm is proposed to find an integral solution of (nonlinear) complementarity problems. The … algorithm starts with a nonnegative integral point and generates a unique sequence of adjacent integral simplices of varying … dimension. Conditions are stated under which the algorithm terminates with a simplex one of whose vertices is an integral …

Perfection and stability of stationary points with applications to noncooperative games
Laan, Gerard van der; Talman, Dolf; Yang, Zaifu - 2002
It is well known that an upper semi-continuous compact- and convex-valued mapping fi from a nonempty compact and convex set X to the Euclidean space of which X is a subset has at least one stationary point, being a point in X at which the image fi(x) has a nonempty intersection with the normal...

On the (Non)-Lattice Structure of Equilibrium Sets in Games with Strategic Substitutes
Roy, Sunanda - 2020
This paper studies models where the optimal response functions under consideration are non-increasing in endogenous variables, and weakly increasing in exogenous parameters. Such models include games with strategic substitutes, and include cases where additionally, some variables may be...

On the solution of Markov-switching rational expectations models
Carravetta, Francesco; Sorge, Marco M. - 2011
This paper describes a method for solving a class of forward-looking Markov-switching Rational Expectations models under noisy measurement, by specifying the unobservable expectations component as a general-measurable function of the observable states of the system, to be determined optimally...

The refined best-response correspondence in normal form games
Balkenborg, Dieter; Hofbauer, Josef; Kuzmics, Christoph - 2012
This paper provides an in-depth study of the (most) refined best reply correspondence introduced by Balkenborg, Hofbauer, and Kuzmics (2012). An example demonstrates that this correspondence can be very different from the standard best reply correspondence. In two-player games, however, the...

Attractive evolutionary equilibria
Roorda, Berend; Joosten, Reinoud - 2011
We present attractiveness, a refinement criterion for evolutionary equilibria. Equilibria surviving this criterion are robust to small perturbations of the underlying payoff system or the dynamics at hand. Furthermore, certain attractive equilibria are equivalent to others for certain...

A characterization of melioration in game theoretic frameworks
Apesteguia, Jose - 2001
The theory of melioration, originally formulated for individual decision-making contexts, is formally extended to a game theoretic framework. This paper proves the existence of a distribution that is a melioration strategy on the part of all players. Further, the question of stability of such a...

Bargaining with Non-Convexities
Herings, P. Jean-Jacques - 2009
We show that in the canonical non-cooperative multilateral bargaining game, a subgame perfect equilibrium exists in pure stationary strategies, even when the space of feasible payoffs is not convex. At such an equilibrium there is no delay. We also have the converse result that randomization...

On securitization, market completion and equilibrium risk transfer
Horst, Ulrich; Pirvu, Traian A.; Reis, Gonçalo Dos - 2010
We propose an equilibrium framework within which to price financial securities written on non- tradable underlyings such as temperature indices. We analyze a financial market with a finite set of agents whose preferences are described by a convex dynamic risk measure generated by the solution of...
