摘要:We consider a dynamic version of sender receiver games, where the sequence of states follows an irreducible Markov chain observed by the sender. Under mild assumptions, we provide a simple characterization of the limit set of equilibrium payoffs, as players become very patient. Under these assumptions, the limit set depends on the Markov chain only through its invariant measure. The (limit) equilibrium payoffs are the feasible payoffs that satisfy an individual rationality condition for the re...

摘要:We analyze an exchange economy of unsecured credit where borrowers have the option to declare bankruptcy in which case they are temporarily excluded from financial markets Endogenous credit limits are imposed that are just tight enough to prevent default. Economies with temporary exclusion differ from their permanent exclusion counterparts in two important properties. If households are extremely patient, then the first-best allocation is an equilibrium in the latter economies but not necessari...

摘要:We study what kind of equilibria of which mechanisms are ex post renegotiation-proof (EPRP), i.e., robust against the possibility of ex post renegotiation under a variety of renegotiation procedures, and which social choice functions are EPRP implementable. In complete information environments with two agents only budget balanced Groves allocations are EPRP implementable, while with three or more agents all ex post efficient allocations are. In environments with independent private values esse...

摘要:This paper demonstrates the theoretical foundation that underlies the willingness of rational arbitrageurs to delay and reinforce the speculative attack. The key assumptions are that there is a small probability that arbitrageurs are behavioral and never time the market of their own accord and it is uncertain whether arbitrageurs are behavioral or rational. We model a stock market as a timing game, in which arbitrageurs compete to react quickest. We show that rational arbitrageurs are willing ...

摘要:Any absolutely continuous, piecewise smooth, symmetric two-player game can be extended to define a population game in which each player interacts with a large representative subset of the entire population. Assuming that players respond to the payoff gradient over a continuous action space, we obtain nonlinear integro-partial differential equations that are numerically tractable and sometimes analytically tractable. Economic applications include oligopoly, growth theory, and financial bubbles ...

摘要:We study allocation rules that are robust to coalitional manipulation by transferring, merging, or splitting individual characteristics among coalition partners (e.g. merging or splitting claims in bankruptcy problems). Coalition formation is restricted by an exogenous network (a non-directed graph) so that only connected subsets of agents can form a coalition. We offer a full characterization of non-manipulable rules without any assumption on the network structure. This result yields a variet...

摘要:This paper opens a new perspective from which one can explain the presence of government intervention in education even in the absence of human capital externality. It argues that consumption externalities can provide rationale for government intervention in education. Within the context of overlapping generations economy, it has also been shown that competitive equilibrium either underaccumulates both physical and human capital or overaccumulates both. Thus the result rules out the possibilit...

摘要:We analyze the preference aggregation problem without the assumption that individuals and society have fully determined and observable preferences. More precisely, we endow individuals and society with sets of possible von Neumann-Morgenstern utility functions over lotteries. We generalize the classical Pareto and Independence of Irrelevant Alternatives axioms and show they imply a generalization of the classical neutrality assumption. We then characterize the class of neutral social welfare f...
