摘要：We consider Bayesian incentive-compatible mechanisms with independent types and either private values or interdependent values that satisfy a form of congruence. We show that in these settings, interim participation constraints are satisfied when the status quo is the randomized allocation that has the same distribution as the equilibrium allocation in the mechanism. Moreover, when utilities are convex in the allocation, we can instead satisfy participation constraints with the deterministic s...

摘要：With complete information, choice of one option over another conveys preference. Yet when search is incomplete, this is not necessarily the case. It may instead reflect unawareness that a superior alternative was available. To separate these phenomena, we consider nonstandard data on the evolution of provisional choices with contemplation time. We characterize precisely when the resulting data could have been generated by a general form of sequential search. We characterize also search that te...

摘要：This paper extends the framework of Kajii and Morris (1997) to study the question of robustness to incomplete information in repeated games. We show that dynamically robust equilibria can be characterized using a one-shot robustness principle that extends the one-shot deviation principle. Using this result, we compute explicitly the set of dynamically robust equilibrium values in the repeated prisoners' dilemma. We show that robustness requirements have sharp intuitive implications regarding w...

摘要：When a firm decides which products to offer or put on display, it takes into account the products' ability to attract attention to the brand name as a whole. Thus, the value of a product to the firmemanates from the consumer demand it directly meets, as well as the indirect demand it generates for the firms' other products. We explore this idea in the context of a stylized model of competition between media content providers (broadcast TV channels, internet portals, newspapers) over consumers ...

摘要：This paper formally examines two competing methods of conducting a lottery to assign students to schools, motivated by the design of the centralized high school student assignment system in New York City. The main result of the paper is that single and multiple lottery mechanisms are equivalent for the problem of allocating students to schools in which students have strict preferences and the schools are indifferent. In proving this result, a new approach is introduced that simplifies and unif...

摘要：Preferences may arise from regret, i.e., from comparisons with alternatives forgone by the decision maker. We ask whether regret-based behavior is consistent with nonexpected utility theories of transitive choice and show that the answer is no. If choices are governed by ex ante regret and rejoicing, then nonexpected utility preferences must be intransitive.
