We study core convergence in interim quasilinear economies with asymmetric information, concentrating on core notions in which information is transmitted endogenously within coalitions and the incentive constraints are relevant. Specifically, we shall focus on the credible core and randomized...

The paper presents and studies a new concept of coalition domination for incomplete markets. It was elaborated applying a contractual approach and based on the notion of fuzzy contractual allocation, see Marakulin (2011, 2013). Core allocations are implemented by the net trades (webs of...

This note applies the evolutionary dynamic of Kandori, Mailath, and Rob ( Econometrica 61 (1993), 29-65) to class coordination games that the entire population plays simultaneously. In these games, payoffs and best replies are determined by a symmary statistic of the population strategy profile...

We study a dynamic mean-variance portfolio optimization problem under the reinforcement learning framework, where an entropy regularizer is introduced to induce exploration. Due to the time-inconsistency involved in a mean-variance criterion, we aim to learn an equilibrium strategy. Under an...

This chapter is devoted to the study of Nash equilibria, and correlated equilibria in both finite and infinite games. We restrict our discussions to only those properties that are somewhat special to the case of two-person games. Many of these properties fail to extend even to three-person...

We are constructing an imperfect competition general equilibrium model, with non-consumable money and labor market; our toolkit is an equilibrium default model of Shubik-Wilson (1978). Our result has an ‘equilibrium volatility' simultaneously occurring at all three markets: labor, goods, and...

This article proposes a two-stage oligopoly model for the crude oil market. In a game of several Stackelberg leaders, market power increases endogenously as the spare capacity of the competitive fringe goes down. This effect is due to the specific cost function characteristics of extractive...

We consider a basic stochastic evolutionary model with rare mutation and a best-reply (or better-reply) selection mechanism. Following Young's papers, we call a state stochastically stable if its long-term relative frequency of occurrence is bounded away from zero as the mutation rate decreases...
