I develop a novel model of group-based deliberation in which communication is costly in two directions: agents must pay separate costs to send and to receive messages. Equilibrium strategies have an intuitive characterization - those with the best information send, those with the worst...

We study the performance of two-sided matching clearinghouses in the laboratory. Our experimental design mimics the Gale-Shapley (1962) mechanism, utilized to match hospitals and interns, schools and pupils, etc., with an array of preference profiles. Several insights come out of our analysis....

We report on an experiment exploring whether and how players may learn to use a random device to coordinate on a correlated equilibrium that Pareto dominates the Nash equilibria of a two-player Battle of the Sexes game. By contrast with other studies exploring recommendations and correlated...

We implement the Battaglini (2002) model of multi-sender-multi-dimension cheap talk in the laboratory, analyzing the effects of sender competition on information transmission. Our results indicate that competing senders provide enough information for close to full revelation, but receiver`s...

We study two provisional fixed-prize mechanisms for funding public goods: an all-pay auction and a lottery. In our setting, the public good is provided only if the participants' contributions are greater than the fixed-prize value; otherwise contributions are refunded. We prove that in this...

We explore the effect of fixed versus dynamic group membership on public good provision. In a novel experimental design, we modify the traditional voluntary contribution mechanism (VCM) by periodically replacing old members of a group with new members over time. Under this dynamic, overlapping...

Over the period of 1995-2005 an increasing number of differentiated products have been exported from developing countries, and much of the growth in world trade at the extensive margin has come from these countries. Leading examples of this type of trade expansion, both in terms of products and...
