This paper offers a model to study the trade-off between the efficiency enhancements of information exchanges and the risk of information leakage in organizations. Information exchanges can be efficient since, in the absence of legal enforcement, the voluntary disclosure of personal information...

This paper uses a new dataset on child-adoption matching to estimate the preferences of potential adoptive parents over US-born and unborn children relinquished for adoption. We identify significant preferences favoring girls and against African American children put up for adoption. These...

We then consider the group of peers (or friends) as an object of choice. We characterize the peer group's optimal composition for each individual in the population. We show that, for each individual, there is a large equivalence class of optimal groups, potentially with maximal variance of...

We analyze the link between entry and R&D spending distribution. We consider a monopolistic competitive market with free entry in which firms can invest in cost-cutting R&D by paying a fixed cost first. For an intermediate level of fixed cost, there is a unique equilibrium in which the market...
