摘要：We present a new solution concept for strategic games called comprehensive rationalizability that embodies a new version of common cautious belief in rationality based on a sound epistemic characterization in a universal type space. Differently from existing iterative strategy elimination procedures in the literature, it should rather be viewed as an iterative strategy demotion procedure as it requires some memory of previously discarded strategies. It refines rationalizability, but it neither...

摘要：The estate division problem considers the issue of dividing an estate when the sum of entitlements is larger than the estate. This paper studies the estate division problem from a noncooperative perspective. The integer claim game introduced by O'Neill (1982) and extended by Atlamaz et al. (2011) is generalized by specifying a sharing rule to divide every interval among the claimants. We show that for all problems for which the sum of entitlements is at most twice the estate the existence of a...

摘要：We study repeated games in which each player i is restricted to (mixtures of) strategies that can recall up to ki stages of history. Characterizing the set of equilibrium payoffs boils down to identifying the individually rational level (punishment level) of each player. In contrast to the classic folk theorem, in which players are unrestricted, punishing a bounded player may involve correlation between the punishers' actions. We show that the extent of such correlation is at most proportional...

摘要：Different sellers often sell the same good at different prices. Using a strategic bargaining model, I characterize how the equilibrium prices of a good depend on the interaction between its sellers' costs, its buyers' values, and a network capturing various frictions associated with trading it. In contrast to the standard random-matching model of bargaining in stationary markets, I allow agents to strategically choose whom to make offers to, which qualitatively changes how the network shapes p...

摘要：In coalition formation games with arbitrary collection of permissible coalitions, a top/stable-coalition condition is sufficient for the existence of a unique core partition, strengthening uniqueness results both in Pycia (2012) and in Banerjee et al.

摘要：In this paper two cost sharing solutions for minimum cost spanning tree problems are introduced, the degree adjusted folk solution and the cost adjusted folk solution. These solutions overcome the problem of the classical reductionist folk solution as they have considerable strict ranking power, without breaking established axioms. As such they provide an affirmative answer to an open question, put forward in Bogomolnaia and Moulin (2010). (C) 2018 Elsevier Inc. All rights reserved.

摘要：This paper is concerned with preference-aggregation rules satisfying desirable efficiency and solidarity requirements. We formulate weaker versions of existing solidarity axioms and show how they imply, in conjunction with strategy-proofness, the existence of reference outcomes holding privileged status. We propose a new class of rules, fixed-order status-quo rules, that can be productively contrasted to their closest counterparts in the literature, status-quo rules based on the least upper bo...

摘要：The lack of price guidance towards efficiency relevant packages in ascending combinatorial clock auctions (ACCA) can lead to a low-efficiency allocation of goods. We propose a descending price combinatorial clock auction (DCCA) with a newly devised pricing strategy to improve on this problem. Using agent-based simulations we document that the DCCA provides significant improvements over the ACCA and we are able to understand in which environments these improvements are likely to be the stronges...

摘要：We analyze the question of how to distribute the asset value of an insolvent firm among its creditors and the firm itself. Compared to standard bankruptcy games as studied in the game-theoretic literature, we treat the firm as a player and define a new class of transferable utility games called liability games. We show that the core of a liability game is empty. We analyze the nucleolus of the game. The firm always gets a positive payment, at most equal to half of the asset value. Creditors wi...

摘要：Recent experimental studies have shown that observed outcomes deviate significantly more from the Nash equilibrium when actions are strategic complements than when they are strategic substitutes. This strategic environment effect offers promising insights into the aggregate consequences of interactions among heterogeneous boundedly rational agents, but its macroeconomic implications have been questioned because the underlying experiments involve a small number of agents. We studied beauty cont...
