摘要:This paper introduces a measure of distribution-sensitivity, which is similar to Arrow-Pratt's measure of risk clr aversion. for a poverty index. The measure also gauges poverty aversion and has a clear and straightforward interpretation. Using this measure. We can define various classes or minimum distribution-sensitive poverty indices. We show that the ordering condition for such a class of poverty indices is simply a generalized (poverty) deprivation profile dominance Properties and implica...

摘要:This paper provides an axiomatic foundation For a maxmin expected utility over a set of priors (MMEU) decision rule in an environment where the elements of choice are Savage acts. This characterization complements the original axiomatization of MMEU developed in a lottery-acts (or Anscombe-Aumann) framework by I. Gilboa and D. Schmeidler (1989 J, Math. Econ. 18, 141-153). MMEU preferences are of interest primarily because they provide a natural and tractable way of modeling decision makers who...

摘要:We analyze investment and pricing incentives in a symmetric Bertrand-Edgeworth framework with uncertain demand. Firms choose production capacities before observing demand. Prices are chosen Lifter demand is observed. if the extent of demand variation exceeds a threshold level then a symmetric equilibrium in pure strategies for capacities does not exist. A smaller firm has no incentive (ex ante) to expand its capacity because capacity expansion would reduce its expected revenue in the event tha...

摘要:In an example, monetary policy can determine the information revealed by prices, and thus it can be: effective. Monetary policy that varies only with public information can guarantee the full revelation of information at equilibrium. which is optimal. Full indexation need not attain full revelation and, as a consequence. need not implement an optimal allocation. Journal of Economic Literature Classification Numbers: D52, D82. E52.

摘要:We present general recursive methods to handle environments where privately observed variables are linked over time. We show that incentive compatible contracts are implemented recursively with a threat keeping constraint in addition to the usual temporary incentive compatibility and promise keeping conditions.

摘要:I consider a three-player Stackelberg. game where each player has its private signal concerning stochastic demand. I show that at a perfectly revealing equilibrium, the second mover earns the lowest and the third mover the highest expected profit of the three. I characterize this result by the strategic substitutes or complements relationships among three firms at the equilibrium. Journal of Economic Literature Classification Numbers: C72, D82, and L13.

摘要:In the present paper general stationary overlapping generations economies with many commodities in every period and many different consumers in every generation are considered. A government maximizes a utilitarian social welfare function, which is the sum of weighted averages of utilities for generations, through fiscal policy, i.e., monetary transfers and taxes. Situations both with and without time discounting are considered. It is shown that if the discount factor is sufficiently close to o...

摘要:We compare rational expectations equilibria with different degrees of information revelation through prices. These equilibria arise in a two-period exchange economy with finitely many states and signals, multiple commodities and incomplete financial markets for nominal assets. We show that there are always equilibria where information is redundant in the sense of being of no value to the uninformed traders. We give conditions under which for a generic set of economies, parametrized by endowmen...

摘要:Consider an exchange economy where agents are arbitragers, in that they try to upset allocations imagining plausible beneficial trades. With an introspective algorithm, each agent constructs an interactive choice set (ICS), i.e., a set of bundles that he considers achievable through a sequence of plausible trades with other agents. We show that Walrasian allocations can he characterized as those where each agent chooses optimally from his ICS, which is always contained in a budget set (with di...

摘要:We study economies (with indivisibilities) that satisfy the gross substitutes (GS) condition. We define an excess demand set with the property that increasing the prices of all goods in excess demand eventually leads to the smallest Walrasian prices. This procedure is a generalization of the auction studied by G, Demange, D. Gale and M. J. Sotomayor, Polit, Econ, 94 (1986), 863-872. In our auction, truthful revelation of demand is a perfect Bayesian equilibrium if the smallest Walrasian prices...
