摘要：We study sequential message-sending games with an uninformed decision maker and multiple self-interested informed agents in which the ability to prove claims is limited. We give necessary and sufficient conditions for the existence of robust inference rules-that is, rules which lead to full, correct inferences even if the decision maker has very little information about speakers' preferences or strategies. Surprisingly little provability is needed when the decision maker only knows that the sp...

摘要：This Note shows that regularity, which is weaker than rationalizability, can be used to prove the random dictatorship result of McLennan (A. McLennan, J. Econ. Theory 22 (1980), 1-11). The result in this Note also shows that in Pattanaik and Peleg (P. K. Pattanaik and B. Peleg, Econometrica 54 (1986), 909-921), when there are at least three alternatives in the universal set, the independence of irrelevant alternatives condition and the requirement that the number of alternatives in the univers...

摘要：We study the asymptotic stability of infinite horizon concave programming problems. By generalizing our preceding work we provide a one-parameter family of conditions that guarantee convergence of the optimal paths to a stationary state. We call this property theta-acyclicity. In the one-dimensional case we show that super-modularity implies our property but not vice versa. We apply theta-acyclicity to a pair of models which study the dynamic behavior of firms that have adjustment costs. The f...

摘要：The question of the existence of a stationary equilibrium for distorted versions of the standard neo-classical growth model is addressed in this paper. The conditions presented guaranteeing the existence of nontrivial equilibrium for the class of economies under study are simple and intuitively appealing, while the existence proof developed is elementary. Examples are given illustrating that economies with distortional taxation, endogenous growth with externalities, and monopolistic competitio...

摘要：Endogenous business cycles have been known to exist ill the overlapping-generations model for quite a long time. The literature seems to imply that these cycles may exist only if individuals show rates of preference for the present that are high enough, and these values must be so high that they are unrealistic. While this observation is true if preferences are homothetic, we show in this paper that, once the homotheticity requirement is dropped, a sufficient condition for the existance of cyc...

摘要：This paper examines the stability of deterministic steady states in a class of economies where the state variable is one dimensional and where agents use Bayesian techniques to form expectations. The dynamics with learning are locally convergent if the prior mean is close to a stable perfect-foresight root having modulus less than 1 and if the prior beliefs are held with enough confidence. The dynamics are, however, divergent if the prior mean or the variance of the prior distribution is suffi...

摘要：This article studies the approximate Bertrand equilibria of a large but finite economy with Free entry for firms and small efficient scales. It establishes the equivalence of the set of regular Walras equilibria of a constant returns to scale limit economy and the set of limits of regular sequences of approximate Bertrand equilibria. This gives a foundation to the Walrasian hypothesis of perfect competition in explaining why firms behave as if they were price-takers and why they set prices tha...

摘要：This paper makes commodities divisible and incorporates bargaining into the search-theoretic model of money to determine the purchasing power of money (or price). It is shown that two monetary equilibria always coexist where fiat money is universally accepted. The two equilibria differ in price, output, welfare, and the velocity of money. Sunspot monetary equilibria exist in which money is universally accepted in all states of the economy. Multiplicity has novel implications on the effectivene...

摘要：This paper studies a dynamic game of perfect information, in which two players start bargaining over the partition of a new cake each time agreement is struck over the partition of an existing cake. Negotiations over the partition of each cake take place according to Rubinstein's alternating-offers model. The parameters of the model are the players' rates of time preference, the time interval between two consecutive offers, and the lag time between the end of one set of negotiations and the st...

摘要：Necessary and sufficient restrictions upon arbitrary utility functions for portfolio separation for any degree are derived for complete markets, generalizing the expected utility theorems of Cass and Stiglitz (J. Econ. Theory 2 (1970), 122-160). Portfolio separation is shown to be nearly synonymous with Lewbel's (Econometrica 59 (1991), 711-730) definition of demand rank, which is characterized using standard duality methods.
