Pairwise Stable Matching in Large Economies
Econometrica, Volume 89, Issue 6, Page 2929-2974, November 2021., 2021 We formulate a stability notion for two‐sided pairwise matching problems with individually insignificant agents in distributional form. Matchings are formulated as joint distributions over the characteristics of the populations to be matched. Spaces of characteristics can be high‐dimensional and need not be compact.

Theoretical Economics, Volume 16, Issue 4, Page 1221-1248, November 2021., 2021 Harris, Reny, and Robson (1995) added a public randomization device to dynamic games with almost perfect information to ensure existence of subgame perfect equilibria (SPE). We show that when Nature's moves are atomless in the original game, public randomization does not enlarge the set of SPE payoffs: any SPE obtained using public randomization can be

Renegotiation of long‐term contracts as part of an implicit agreement
Theoretical Economics, Volume 16, Issue 4, Page 1471-1512, November 2021., 2021 I study a repeated principal–agent game with long‐term output contracts that can be renegotiated at will. Actions are observable but not contractible, so they can only be incentivized through implicit agreements formed in equilibrium. I show that contract renegotiation is a powerful tool for incentive provision, despite the stationarity of the ...

Strict pure strategy Nash equilibria in large finite‐player games
Theoretical Economics, Volume 16, Issue 3, Page 1055-1093, July 2021., 2021 In the context of anonymous games (i.e., games where the payoff of a player is, apart from his/her own action, determined by the distribution of the actions made by the other players), we present a model in which, generically (in a precise sense), finite‐player games have strict pure strategy Nash equilibria if the number of agents is large.

A necessary and sufficient condition for upper hemicontinuous set-valued mappings without compact-values being upper demicontinuous [PDF]
Proceedings of the American Mathematical Society, 1998 The purpose of this article is to give a characterization of an upper hemicontinuous mapping with non-empty convex values being upper demicontinuous, i.e., we show that an upper hemicontinuous set-valued mapping with non-empty convex values (not necessarily compact-valued) is upper demicontinuous if and only if the set-valued mapping has no interior ...

Brezis Pseudomonotonicity is Strictly Weaker than Ky–Fan Hemicontinuity [PDF]
Journal of Optimization Theory and Applications, 2018 In 1968, H. Brezis introduced a notion of operator pseudomonotonicity which provides a unified approach to monotone and nonmonotone variational inequalities (VIs). A closely related notion is that of Ky-Fan hemicontinuity, a continuity property which arises if the famous Ky-Fan minimax inequality is applied to the VI framework.

On well-posedness associated with a class of controlled variational inequalities
, 2021 In this paper, by using the new concepts of monotonicity, pseudomonotonicity and hemicontinuity associated with the considered curvilinear integral functional, we investigate the well-posedness and well-posedness in generalized sense for a class of ...

Some remarks on lower hemicontinuity of convex multivalued mappings [PDF]
, 2004 For a multifunction a condition sufficient for lower hemicontinuity is presented. It is shown that under convexity of graph it is possible for a multifunction to be not continuous only when a special representation of points of its domain is not ...

Penalty methods for a system of constrained variational inequalities
, 2012 International audienceIn this paper, using the penalty method in conjunction with graph-convergence, we study the existence of solutions for a class of generalized variational inequalities with variational problem constraints. Our results extend, improve
