We present a necessary and almost sufftcient condition for subgame perfect implementation of social choice correspondences. In societies with at least three individuals, any social choice correspondence which satisfies no veto power and our necessary Condition a is subgame perfect implementable. Thus Condition GL is analogous to monotonicity which, by Maskin’s celebrated characterization, is ne...

a constitutive model based on two–dimensional unstructured galerkin finite volume method (gfvm) is introduced and applied for analyzing nonlinear behavior of cracked concrete structures in equilibrium condition. the developed iterative solver treats concrete as an orthotropic nonlinear material and considers the softening and hardening behavior of concrete under compression and tension by using...

In a standard two country international macro model we ask whether shutting down the market for international non-contingent borrowing and lending is ever desirable. The answer is yes. Imposing capital controls is unilaterally desirable when initial conditions are such that ruling out bond trade generates a sufficiently favorable change in the expected path for the terms of trade. Imposing capi...

We analyze the distributed power allocation problem in parallel multiple access channels (MAC) by studying an associated non-cooperative game which admits an exact potential function. Even though games of this type have been the subject of considerable study in the literature [1–4], we find that the sufficient conditions which ensure uniqueness of Nash equilibrium points typically do not hold i...

] proposed a classical algorithm to break through Maskin's theorem for the case of many agents. In this paper, we will give two examples to break through the aforementioned results on two-agent Nash implementation by virtue of Wu's algorithm. There are two main contributions of this paper: 1) A two-player social choice rule (SCR) that satisfies Condition µ2 cannot be Nash implemented if an addi...

We present a class of games with a pure strategy being strictly dominated by another pure strategy such that the former survives along solutions of the Brown–von Neumann–Nash dynamics from an open set of initial conditions. JEL classification: C72

This work studies the convergence properties of continuous-time fictitious play in potential games. It is shown that in almost every potential game and for almost every initial condition, fictitious play converges to a pure-strategy Nash equilibrium. We focus our study on the class of regular potential games; i.e., the set of potential games in which all Nash equilibria are regular. As byproduc...

In this paper, bi-matrix games are investigated based on L-R fuzzy variables. Also, based on the fuzzy max order several models in non-symmetrical L-R fuzzy environment is constructed and the existence condition of Nash equilibrium strategies of the fuzzy bi-matrix games is proposed. At last, based on the Nash equilibrium of crisp parametric bi-matrix games, we obtain the Pareto and weak Pareto...
