Despite the truthful dominant strategy, participants in strategy-proof me- chanisms submit manipulated preferences. In our model, participants dislike rejections and enjoy the confirmation from getting what they declared most desirable. Formally, the payoff from a match decreases in its position...

Extensive evidence suggests that participants in the direct student-proposing deferred-acceptance mechanism (DSPDA) play dominated strategies. In particular, students with low priority tend to misrepresent their preferences for popular schools. To explain the observed data, we introduce...

In this paper, I argue that religion matters for the emergence of democracies and dictatorships. Religion is defined as a stochastically set demand for public goods. Different types of religious collectives reflect different tradeoffs between centralized resource distribution and market rewards....

We assess the influence of moneyed interests on legislative decisions. Our theory predicts that the vote outcome distribution and donation flows in a legislature feature a discontinuity at the approval threshold of bills if special interest groups are involved in vote buying. Testing the...

Why do politicians sometimes pursue policies with uncertain outcomes? We present a model in which politicians are unable to pre-commit to a status quo policy, and where investors and voters face a conflict over the division of output. Politicians may deviate from the status quo and pursue risky...

In mechanism design, Myerson regularity is often too weak for a quantitative analysis of performance. For instance, ratios between revenue and welfare, or sales probabilities may vanish at the boundary of Myerson regularity. This paper therefore explores the quantitative version of Myerson...

We study road congestion as a mechanism design problem. In our basic model we analyze the allocation of a set of drivers among two roads, one of which may be congested. An additional driver on the congestible road imposes an externality on the other drivers by increasing their travel time. Each...

In school choice problems, the widely used manipulable Immediate Acceptance mechanism (IA) disadvantages unsophisticated applicants, but may ex-ante Pareto dominate any strategy-proof alternative. In these cases, it may be preferable to aid applicants within IA, rather than to abandon it. In a...

This paper shows that the possibility of collusion between an agent and a supervisor imposes no restrictions on the set of implementable social choice functions (SCF) and associated payoff vectors. Any SCF and any payoff profile that are implementable if the supervisor's information was public...
