摘要：We analyze a complete information multilateral bargaining model in which a buyer is to purchase two complementary goods from two sellers. Binding cash-offer contracts are used to govern transactions. In contrast to preexisting literature, we do not normalize the parties' reservation utilities to zero. We show that this assumption holds critical importance by demonstrating that a complete breakdown of negotiations may occur as the unique equilibrium outcome, even if only two sellers are present...

摘要：Workers in less-secure jobs are often paid less than identical-looking workers in more secure jobs. We show that this lack of compensating differentials for unemployment risk can arise in equilibrium when all workers are identical and firms differ only in job security (i.e. the probability that the worker is not sent into unemployment). In a setting where workers search for new positions both on and off the job, the worker's marginal willingness to pay for job security is endogenous, increasin...

摘要：We prove that a single-valued solution of perfectly competitive TU economies underlying nonatomic exact market games is uniquely determined as the Mertens [23] value by four plausible value-related axioms. Since the Mertens value is always a core element, this result provides an axiomatization of the Mertens value as a core-selection. Previous works in this direction assumed the economies to be either differentiable (e.g., Dubey and Neyman [11]) or of uniform finite-type (e.g., Haimanko [16])....

摘要：We study efficiency and fairness properties of the equal cost sharing with maximal participation (ECSMP) mechanism in the provision of a binary and excludable public good. According to the maximal welfare loss criterion, the ECSMP is optimal within the class of strategyproof, individually rational and no-deficit mechanisms only when there are two agents. In general the ECSMP mechanism is not optimal: we provide a class of mechanisms obtained by symmetric perturbations of ECSMP with strictly lo...

摘要：We investigate conditions for endogenous incompleteness and completeness in continuous-time financial markets driven by diffusion processes with multiple consumption goods and heterogeneous agents. We show that for a class of utility functions the financial market is endogenously incomplete. A sufficient condition for market completeness is that the dividend diffusion matrix in units of the numeraire good is invertible. Further, financial market completeness can depend on the choice of the num...

摘要：This paper develops a theoretical foundation for the undercut-proof equilibrium (see Shy, 1996, 2002; Morgan and Shy, 2015). In a general spatial setting, the set of undercut-proof prices is equivalent to the core of a non-transferable utility coalitional-game, played on the set of outcomes that are feasible in Bertrand competition. The result depends critically on two conditions: First, firms must have unlimited capacity and constant marginal costs. Second, the goods produced by firms must on...

摘要：We study a model where some agents have private information about risky asset returns and trade to obtain capital gains, while others acquire the risky asset and hold it to maturity, forming expectations of returns based on market prices. We show that under such a structure, in addition to fully revealing rational expectations equilibria, there exists a continuum of equilibrium prices consistent with rational expectations, where the asset prices are subject to sunspot shocks. Such sunspot shoc...

摘要：The nonemptiness of the alpha-core of games with continuous payoff functions was proved by Scarf (1971) for nontransferable utilities and by Zhao (1999) for transferable utilities. In this paper we present generalizations of their results to games with possibly discontinuous payoff functions. Our handling of discontinuity is based on Reny's (1999) better-reply-security concept. We present examples to show that our generalizations are nonvacuous. (C) 2015 Elsevier Inc. All rights reserved.

摘要：This paper proposes a micro-foundation for knowledge spillovers. I model a city in which free knowledge transfers are bids by experts to entrepreneurs who auction jobs. These knowledge bids resemble a consultant's pitch to a potential client. Two fundamental properties of knowledge underlie the model: First, it is often necessary to reveal some knowledge to demonstrate its value. Second, knowledge is freely reproducible. Larger cities generate more meetings between experts and entrepreneurs, r...

摘要：We consider a two-player Prisoner's Dilemma type game with continuous actions, where players choose how much to contribute to a public project. This game is played infinitely many times and actions are irreversible: players cannot decrease their actions over time. While it is strictly dominant for players not to contribute in the stage game, some strictly positive level of contribution is Pareto optimal. It is known that when players perfectly observe each other's actions, cooperation can be a...
