摘要：In many real-world matching applications, there are restrictions for institutions either on priorities of their slots or on the transferability of unfilled slots over others (or both). Motivated by the need in such real-life matching problems, this paper formulates a family of practical choice rules, slot-specific priorities with capacity transfers (SSPwCT). These rules invoke both slot-specific priorities structure and transferability of vacant slots. We show that the cumulative offer mechani...

摘要：This paper studies the dynamics of effort provision in teams when there are exogenous observation delays between partners. Agents are engaged in a common project whose duration is uncertain and yields no benefit until one of them has completed it. All it takes to complete the project is one success, which can be obtained after the investment of costly effort. An agent learns immediately when he succeeds but learns whether his partners succeeded after some delay. In equilibrium, players alterna...

摘要：We prove that the Maskin monotonicity* condition (proposed by Bergemann et al. (2011)) fully characterizes exact rationalizable implementation in an environment with lotteries and transfers. Different from previous papers, our approach possesses many appealing features simultaneously, e.g., finite mechanisms with no integer game or modulo game are used; no transfers are made in any rationalizable profile; the message space is small; the implementation is robust to information perturbations in ...

摘要：The concept of unprejudiced beliefs equilibrium is simple: out-of-equilibrium beliefs should be consistent with the principle that multiple deviations are infinitely less likely than single deviations. Our questions are: does there always exist such an equilibrium and what can be done if there are multiple such equilibria? To select a unique equilibrium, this notion is usually coupled with the intuitive criterion. The simultaneous usage of these concepts is ad hoc, unjustified, and again might...

摘要：We present a characterization of the Luce rule in terms of positivity and a new choice axiom called odds supermodularity that strengthens the regularity axiom. This new characterization illuminates a connection that goes unnoticed, and sheds light on the behavioral underpinnings of the Luce rule and its extensions from a different perspective. We show that odds supermodularity per se characterizes a structured extension of the Luce rule that accommodates zero probability choices. We identify t...

摘要：An uninformed principal appoints a committee of experts to vote on a multi-attribute alternative, such as an interdisciplinary project. Each expert evaluates one attribute and is biased toward it (specialty bias). The principal values all attributes equally but has a status quo bias, reflecting the organizational cost of a change. We study whether the principal would compose the committee of more or less specialty-biased experts. We show that her optimal composition is nonmonotonic in the majo...

摘要：I consider the housing market problem with weak preferences. In this context, I provide a sufficient condition for weak group strategy proofness; no group of agents can jointly misreport their preferences such that each agent in the group becomes better-off. Using this sufficient condition, I prove that the top trading absorbing sets, top cycles, and highest priority objectrules satisfy weak group strategy proofness. Thus, this paper establishes that it is possible to achieve weak group strate...

摘要：We experimentally compare two natural mechanisms for the collective choice of an allocation of a fixed budget to a number of divisible public projects: the mean rule that implements the average of all individual proposals, and a suitably normalized median rule. Theoretical results predict extreme voting behavior in equilibrium under the mean rule and frequently sincere voting under the normalized median rule. Our findings confirm equilibrium behavior under the mean rule in situations in which ...

摘要：We identify a condition on preference domains that ensures that every locally strategy-proof and unanimous random social choice function is also strategy-proof. Furthermore every unanimous, locally strategy-proof deterministic social choice function is also group strategy-proof. The condition identified is significantly weaker than the characterization condition for local-global equivalence without unanimity in Kumar et al. (2020). The condition is not necessary for equivalence with unanimous ...

摘要：We examine the prevalence of gradualist strategies and their effect on trust-building and economic gains in a setting with an infinite horizon, asymmetric information regarding the trustworthiness of receivers, and various levels of trust. The theoretical literature suggests that gradualist strategies mitigate asymmetric information problems and foster trust-building. However, we theoretically and experimentally show that gradualism sometimes reduces joint payoffs relative to a simple binary s...
