We consider a model in which educational investments entail productivity gains, signaling power, and social returns. The latter depend on the relative position the agent occupies in one of three di¤erent dimensions: (i) his innate characteristics, (ii) his level of schooling, and (iii) his...

We study how the closeness of electoral race affect the number of invalid ballots under the traditional paper-ballot voting technology. Using a large dataset from the Italian parliamentary elections in 1994-2001, we find a strong positive correlation between the closeness of electoral race and...

This note introduces and discusses the concept of pu-dominance in the context of finite games in normal form. It then presents the pu-dominance criterion for equi- librium selection. The pu-dominance criterion is inspired by and closely related to the p-dominance criterion (Morris et al., 1995)...

We introduce and examine a game in which players can steal parts of a homo- geneous and perfectly divisible pie from each other. The expected effectiveness of a player's theft is proportional to the share of the pie he currently owns. We show how the incentives to preempt or to follow the rivals...

We study a rent-seeking contest in which players have heterogeneous and private valuations. In addition to their own type, agents only know that all valuations are drawn from an unspeciÂ…ed distribution, of which they only know the mean. We obtain a closed-form solution for agentsÂ’...

This paper formalizes the pervasive phenomenon of the self-serving bias within the framework of reference dependent preferences. This formulation allows the stating of a simple rule to assess the existence of the bias at the aggregate level as well as a procedure that identifies the minimum...

Is the decline in voter turnout an indicator of a worse health of a representative democracy? We build a simple probabilistic-voting model with endogenous turnout to address this question. We ?nd that a lower turnout caused by a higher cost of voting implies higher political rents. Contrarily, a...

Mission-driven nonprofi?t organizations compete for donations through fundrais- ing activities. Such competition can lead to inefficient outcomes, if nonpro?fits impose ex- ternalities on each others? output. This paper studies the design of sustainable voluntary cooperation agreements, using a...

Randomized controlled trials (RCT) have become a dominant empirical tool in applied economics. The internal validity of RCTs crucially depends on the (implicit) assumption that the procedure assigning subjects to treatment and control groups has no effect on behavior. We show theoretically that...

We show how the common occurrence of seeing exceedingly high claims in disputes and litigations about how to share a limited resource can be rationalized by a model in which claimants display reference dependent preferences, expect the judge to use a generalized social welfare function, and...
