摘要：In a differentiated-product Cournot model, each supplier receives informative signals about demand. The cross-industry correlations of the signals differ: more public signals have higher correlation coefficients. In equilibrium, information is used inefficiently. From the industry's perspective, information is over-used, and too much emphasis is placed on relatively public signals; from the consumer's perspective, information is under-used, and too much emphasis is placed on relatively private...

摘要：Altruism refers to a willingness to benefit others, even at one's own expense. In contrast, selfishness refers to prioritizing one's own interests with no consideration for others. However, even if an agent is selfish, he might nevertheless act as if he were altruistic out of selfish concerns triggered when his action is observed; that is, he might seek to feel pride in acting altruistically and to avoid the shame of acting selfishly. We call such behavior impurely altruistic. Alternatively, e...

摘要：Under which condition does the set of desirable uncertain prospects expand when wealth increases? We show that the decreasing concavity (DC) of the utility function u is necessary and sufficient in the alpha-maxmin expected utility model. in the smooth ambiguity aversion model with the ambiguity valuation function phi, the DC of u and of phi o u is is necessary and sufficient. An alternative classical definition of decreasing aversion is based on the hypothesis that the investment in a risky a...

摘要：This paper considers general games in which multiple informed principals simultaneously compete to influence the decisions of a common agent. It shows that we can characterize all outcomes of any game in which principals delegate the final decisions to the agent using arbitrary mechanisms, by studying a simpler game in which they can offer only menus of decisions and send cheap-talk signals to the agent. For games in which the principals instead participate in making final decisions, we can ch...

摘要：In a Markov game, players engage in a sequence of games determined by a Markov process. In this setting, this paper investigates the impact of varying the informativeness of public information, as defined by Blackwell [8,9], pertaining to the games that will be played in future periods. In brief, when a curvature condition on payoffs is satisfied, the finding is that, for any fixed discount factor, the set of strongly symmetric subgame perfect equilibrium payoffs of a Markov game with more inf...

摘要：This paper studies price dynamics in a setting in which a monopolist sells a new experience good over time to many buyers, and the seller can neither price discriminate among the buyers nor commit to a price rule. Buyers learn from their own experiences about the effectiveness of the product. Individual learning generates ex post heterogeneity, which affects the buyers' purchasing decisions, the monopolist's pricing strategy, and efficiency. When learning occurs through good news signals, buye...

摘要：The Introduction to the Symposium Issue on Dynamic Contracts and Mechanism Design of the Journal of Economic Theory provides an overview of the dynamic mechanism design literature. We then introduce the papers that are contained in the Symposium issue and finally conclude by discussing avenues for future research. Several of the papers contained in the Symposium issue were presented at the Economic Theory Workshop of the Cowles Foundation for Research in Economics at Yale University in June 20...

摘要：We characterize the product line choice and pricing of a monopolist from the upper envelope of net marginal revenue curves to the individual product demand functions. The equilibrium product line constitutes those varieties yielding the highest upper envelope. In a generalized vertical differentiation framework, the equilibrium line is exactly the same as the first-best socially optimal line. These upper envelope and first-best optimal line findings extend to symmetric Cournot oligopoly. (C) 2...

摘要：In a class of informed principal problems with common values, we define iteratively a particular allocation which we call the assured allocation. It is comparatively easy to calculate and straightforward to interpret. It always exists, is unique and continuous in the priors. It is undominated, i.e. efficient among the different types of the principal subject to the agent's interim participation constraint. It is a perfect Bayesian equilibrium of the three-stage game in Myerson [16] and Maskin ...

摘要：We analyze a market populated by expected utility maximizers and smooth ambiguity-averse consumers. We study conditions under which ambiguity-averse consumers survive and affect prices in the limit. If ambiguity vanishes with time or if the economy exhibits no aggregate risk, ambiguity-averse consumers survive, but have no long-run impact on prices. In both scenarios ambiguity-averse consumers are fully insured against ambiguity in equilibrium and thus behave as expected utility maximizers wit...
