摘要：We examine the effect of ambiguity in symmetric games with aggregate externalities. We find that ambiguity will increase/decrease the equilibrium strategy in games with strategic complements/substitutes and positive externalities. These effects are reversed in games with negative externalities. We consider some economic applications of these results to Cournot oligopoly, bargaining, macroeconomic coordination, and voluntary donations to a public good. In particular we show that ambiguity may r...

摘要：We prove the Folk theorem for the Prisoner's dilemma using strategies that are robust to private monitoring. From this follows a limit folk theorem: when players are patient and monitoring is sufficiently accurate, (but private and possibly independent) any feasible individually rational payoff can be obtained in sequential equilibrium. The strategies used can be implemented by finite (randomizing) automata. (C) 2001 Elsevier Science.

摘要：In this paper, I study a repeated Prisoner's Dilemma game in which monitoring is private and imperfect. A partial folk theorem is proved for the case of almost perfect monitoring. (C) 2001 Elsevier Science.

摘要：We consider house allocation without endowments. We show that there is a unique maximal domain including all strict preference on which efficancy and coalitional strategygy-proofness are compatible, A preferenc relation belongs to the unique maximal domain if it is a strict descending ranking of houses to a certain house and indifference holds over it and the remaining house. We also show that on this domain mixed dictator-pairwise-exchange rules are the only rules satisfying efficiency and co...

摘要：Collective decision problems are considered with a finite number of agents who have single-peaked preferences oil the real line. A probabilistic decision scheme assigns a probability distribution over the real line to every profile of reported preferences. The main result of the paper is a characterisation of the class of unanimous and strategy-proof probabilistic schemes with the aid of fixed probability distributions that play a role similar to that of the phantom voters in H. Moulin (Public...

摘要：We use a very standard life-cycle growth model, in which individuals have a labor-leisure choice in each period of their lives, to prove that an optimizing government will almost always find it optimal to tax or subsidize interest income, The intuition for our result is straightforward. In a life-cycle model the individual's optimal consumption-work plan is almost never constant and an optimizing government almost always taxes consumption goods and labor earnings at different rates over an ind...

摘要：We formally explore Jacobs' idea that uncompensated knowledge spillovers are crucial for agglomeration by modeling location-dependent interfirm production externalities in a general-equilibrium linear-city framework. Good and factor allocation, firms' and households' locational choice, and wages and land rents are all endogenously determined. The unique equilibrium urban configuration may be concentrated (with monocentric firm locations), dispersed (with completely mixed firm/household locatio...

摘要：We study how economic growth is affected by demographics in an OLG model with a realistic survival law. Individuals optimally chose the dates at which they leave school to work and at which they retire. Endogenous growth arises thanks to the accumulation of generation-specific human capital. Favorable shifts in the survival probabilities induce longer schooling and later retirement but have an ambiguous effect on per-capita growth, The long-term relationship between fertility and per-capita gr...

摘要：We analyze financial collapses, such as the one that occurred during the U.S. Great Depression, from the perspective of a monetary model with multiple equilibria. The multiplicity arises from the presence of a strategic complementarity due to increasing returns to scale in the intermediation process. Intermediaries provide the link between savers and firms who require working capital for production. Fluctuations in the intermediation process are driven by variations in the confidence agents pl...

摘要：This paper investigates the optimal contract design in a principal agent model where verification of an agent's action is endogenously determined through strategic interactions between contracting parties. We derive a necessary and sufficient condition for the first best outcome to be implemented as an equilibrium, The equilibrium has the following features (i) The action level that the agent chooses is not verified even if it is possible. (ii) Nevertheless. the first best can be attained by m...
