摘要：This paper analyzes the optimal menu of contracts offered by a risk-neutral principal to a risk-averse agent under moral hazard, adverse selection, and limited liability. We show that a limited liability constraint causes pooling of the most efficient agent types. We also find sufficient conditions under which full pooling is optimal, regardless of the agent's risk aversion or type distribution. Our model suggests that offering a single contract is often optimal in environments with moral haza...

摘要：Preregistration requires scientists to describe the planned research activities before their project begins. Preregistration improves transparency in empirical research and is an institutional response to scientific misconduct. This paper studies the impact of a preregistration requirement in a model in which a sender can generate information for a receiver by running private experiments. The sender can also engage in uninformative manipulation. This paper argues that a preregistration require...

摘要：We study collusion in a second-price auction with two bidders in a dynamic environment. One bidder can make a take-it-or-leave-it collusion proposal, which consists of both an offer and a request of bribes, to the opponent. We show that there always exists a robust equilibrium in which the collusion success probability is one. In the equilibrium, for each type of initiator the expected payoff is generally higher than the counterpart in any robust equilibria of the single-option model (Eso and ...

摘要：An absorbing game is a two-person zero-sum repeated game. Some of the entries are absorbing in the sense that, following the play of an absorbing entry, with positive probability all future payoffs are equal to that entry's payoff. The outcome of the game is the long-run average payoff. We prove that a two-person zero-sum absorbing game, with either finite or compact action sets, has, for each epsilon > 0, epsilon-optimal strategies with finite memory. In fact, we show that there is an epsilon...

摘要：Vote trading is ubiquitous in committees and legislatures, and yet we know very little about its properties. We explore this subject with a laboratory experiment. We propose a model of vote trading in which pairs of voters exchange votes whenever doing so is mutually advantageous. The resulting trading dynamics always converge to stable vote allocations-allocations where no further improving trades exist. The data show that stability has predictive power: vote allocations in the lab converge t...

摘要：I propose and axiomatically characterize a multi-attribute stochastic choice model that simultaneously generalizes the standard model of deterministic choice and the Luce rule. Attributes are cardinal, independent measures of desirability that are endogenously inferred from observed choices, and thus subjective. An alternative is chosen with a positive probability from a menu if and only if it is undominated attribute-wise in that menu. The model leads to the context-dependent evaluation of al...

摘要：We theoretically and experimentally study the evolution of strategies reflecting different moral judgments under indirect reciprocity. We fully characterize the asymptotically stable sets of rest points. In all cooperative rest points multiple strategies coexist. This offers an explanation for the heterogeneity in moral judgments among humans. The behavior prescribed by the predicted strategies can rationalize the design of real-life reputation systems, which are set up to resolve problems of ...

摘要：Organizations and policymakers increasingly rely on economic incentives to prompt participation in activities amongst those who were previously not engaged. We ran a field experiment with a recycling program to examine incentives' effectiveness to motivate new behavior-i.e., attract non-recyclers. We compared standard contingent incentives (payment contingent on recycling) to non-contingent incentives (upfront unconditional payment) of different sizes. A high contingent incentive was as effect...

摘要：We perform a stochastic stability analysis with observation errors. Players recurrently play a symmetric two-player normal form game with one another and respond to the strategy distribution of other players. In each period, a revising player observes the strategy distribution and chooses a best response to it. Her observation is perturbed with positive probability and she may respond to the misperceived strategy distribution. The robustness of Nash equilibria to such observation errors is exa...
