摘要：The paper considers repeated games where each player can be observed by only a subset of the other players, and where players can make public announcements about the behavior of the players they observed. We address the following question: What is the minimal level of observability that is required to obtain efficient outcomes? The main result is that the limit set of sequential equilibrium payoffs, when the discount factor tends to one, contains the set of individual rational payoffs whenever...

摘要：When the arrival of traders at the market is stochastic, and it is impossible for traders who might arrive to meet ex ante, then Walrasian spot-market clearing presents consumers with price-risk and is typically not Pareto optimal. Instead. with an indivisible good and a divisible numeraire, the first-best can be achieved by an ''Exchange'' selling raffle tickers at a fixed price. When only spot market trading is feasible and consumers cannot commit to pay unless they purchase the indivisible ...

摘要：We analyze the class of increasing utility functions exhibiting all derivatives of alternating sign. This property, that we call mixed risk aversion, is satisfied by the utility functions most commonly used in financial economics. The utility functions displaying mixed risk aversion can be expressed as mixtures of exponential functions. We characterize stochastic dominance and we find conditions for both mutual aggravation and mutual amelioration of risks when agents are mixed risk averse. Fin...

摘要：A class of evolutionary selection dynamics is defined, and the defining property convex monotonicity. is shown to be sufficient and essentially necessary for the elimination of strictly dominated pure strategies. More precisely: (1) all strictly dominated strategies :Ire eliminated along all interior solutions in all convex monotonic dynamics. and (2) for all selection dynamics where the pure-strategy growth rates are functions of their current payoffs, violation of convex monotonicity implies...

摘要：This paper analyzes conservation and extinction of renewable resources when the production function is nonconcave and the return function depends on consumption and the resource stock. The paper focuses on the efficiency of global conservation, a safe standard of conservation, and extinction. Which outcome obtains depends on the marginal rate of substitution between investment and the stock in addition to the discount Factor and the marginal productivity of the resource. Conservation may be ef...

摘要：In many circumstances, a principal who has private information when contracting with an agent may perform some further action simultaneously with (or after) the agent's choice of an action. We analyze such a principal-agent relationship with an informed principal as a noncooperative game and distinguish two extensive-form games. First, the principal can commit to his subsequent action at the time of contracting. Second, the principal's announcement for his action is not binding at the time of ...

摘要：We explore the relationship between R. W. Shephard's input distance function (''Cost and Production Functions,'' Princeton Univ. Press, Princeton, 1953) and D. G. Luenberger's benefit function (J. Math. Econ. 21 (1992a), 461-481). We point out that the latter can be recognized in a production context as a directional input distance function which can exhaustively characterize technologies in both price and input space. D. McFadden's (Cost, revenue, and profit functions, in ''Production Economi...

摘要：This study derives the least upper bound of discount factors of future utilities for which a cyclical optimal period-three path emerges in a standard model of optimal growth. For this purpose. we characterize a cyclical optimal period-three path by a dual path or prices. We then demonstrate that a condition far the existence of a cyclical optimal period-three path can be expressed by the existence of a solution to a sytem of linear equations. By solving this system, we demonstrate that the lea...

摘要：Existing equilibrium refinements rule out Nash equilibria susceptible to deviations. We propose a framework for considering not only equilibria impervious to deviations, but also equilibria likely to recur in the long run because they are repeatedly deviated to. We explore which equilibria are recurrent with respect to the deviations underlying some existing signaling refinements. We show that the set of recurrent equilibria based on Cho and Kreps's (1987) intuitive criterion is equivalent to ...

摘要：We consider the problem of electing candidates in situations where the number of candidates and the number of voters may vary. An election consists of a set of candidates and a set of voters. A voting rule associates a non-empty subset of candidates with each election. We show that there is only one rule that satisfies neutrality, anonymity, independence of dominated candidates, and reinforcement. The rule is known as plurality rule: It elects the candidates that are ranked first by the larges...
