Recent funding problems experienced by European sovereigns and the subsequent policy actions taken by European authorities have renewed interest in the international Lender of Last Resort (LLR). This paper constructs a global game LLR model applicable to both domestic and international contexts,...

We apply farsighted stable set to two versions of Hotelling's location games: one with linear market and another with circular market. It is shown that there always exists a farsighted stable set in both games. In particular, the set of all location profiles that yields equal payoff across all...

This paper considers the macroeconomic effects of retailers' market concentration and buyer-size discounts on inflation dynamics. During Japan's “lost decades,” large retailers enhanced their market power, leading to increased exploitation of buyer-size discounts in procuring goods. We...

Interval games are an extension of cooperative coalitional games, in which players are assumed to face payoff uncertainty. Characteristic functions thus assign a closed interval instead of a real number. This study revisits two interval game versions of Shapley values (i.e., the interval Shapley...

Interval games are an extension of cooperative coalitional games in which players are assumed to face payoff uncertainty as represented by a closed interval. In this study, we examine two interval-game versions of Shapley values (i.e., the interval Shapley value and the interval Shapley-like...
