摘要：In the assignment problem where agents can stay unassigned, the size of the assignment is an important consideration for designers. Bogomolnaia and Moulin (2015) show that there is a tension between size and fairness: the guaranteed size ratio of any envy-free mechanism is at most r(m), which converges decreasingly to 1 - 1/e approximate to 63.2% as the maximum size increases. They then ask whether r(m) is also the guaranteed size ratio for any ordinally efficient and envy-free mechanism. We s...

摘要：Given a skew-symmetric matrix, the corresponding two-player symmetric zero-sum game is defined as follows: one player, the row player, chooses a row and the other player, the column player, chooses a column. The payoff of the row player is given by the corresponding matrix entry, the column player receives the negative of the row player. A randomized strategy is optimal if it guarantees an expected payoff of at least 0 for a player independently of the strategy of the other player. We determin...

摘要：In the Approval Bargaining game, two players bargain over a finite set of alternatives. To this end, each one simultaneously submits a utility function u jointly with a real number a; by doing so she approves the lotteries whose expected utility according to u is at least a. The lottery to be implemented is randomly selected among the most approved ones. We first prove that there is an equilibrium where players truthfully reveal their utility function. We also show that, in any equilibrium, th...

摘要：Using a standard strategic pricing game, I determine how sellers set prices when facing buyers who are rationally inattentive to information about product quality. Two cases are studied: strategically sophisticated buyers who are rationally inattentive to exogenous information about quality and strategically naive buyers who are rationally inattentive to strategic information about quality. In both cases, there exists an equilibrium where high quality sellers price high and low quality sellers...

摘要：We develop a model of many-to-many matching with contracts that subsumes as special cases many-to-many matching markets and buyer-seller markets with heterogeneous and indivisible goods. In our setting, substitutable preferences are sufficient to guarantee the existence of stable outcomes; moreover, in contrast to results for the setting of many to -one matching with contracts, if any agent's preferences are not substitutable, then the existence of a stable outcome can not be guaranteed. In ma...

摘要：The psychology and behavioral economics literatures show that real world decision making at the individual level is frequently inconsistent with the rational actor model. An important question is therefore the extent to which a proportion of agents who make mistakes affects market level outcomes. Previous theoretical and experimental research showed that market level outcomes are less likely to match the rational actor model in settings characterized by strategic complementarity and more likel...

摘要：In this study, we consider priority-based matching problems in which indifferent priorities are allowed. Although indifferences in priorities are naturally present in practice, it is unknown whether constrained efficient stable matchings are implementable in any strategic solution concept. Therefore, in this study, we show that (1) stable matchings are Nash implementable via a practical mechanism and (2) constrained efficient stable matchings are Nash implementable if and only if priorities sa...

摘要：I study the implications of Wald's (1947) complete class theorem for decision making under Knightian uncertainty (or ambiguity). Suppose we call someone who uses Wald's approach to statistical decision making a Waldian. A Waldian may then have preferences over acts that are not in agreement with subjective expected utility but always chooses as if she was a subjective expected utility maximizer. In particular, even Wald's (1945) minmax decision rule is consistent with subjective expected utili...

摘要：We study non-stationary markets in which traders are randomly matched to bargain over the price of a heterogeneous good or the terms of a partnership. The economy consists of a continuum of players drawn from a finite set of types. Players exogenously enter the market over time and exit upon trading. At every date, matching probabilities for each pair of types are determined by the endogenous distribution of trader types in the market. The balance of bargaining power at any stage depends on va...

摘要：Multiple attribute search is a central feature of economic life: we consider much more than price when purchasing a home, and more than wage when choosing a job. Nevertheless, while single attribute search problems have been studied extensively, little is known about optimal search in multiple attribute environments. I introduce a partial characterization of optimal sequential search in a problem with multiple searchable attributes and alternatives, no order restrictions on search, and full re...
