We extend Krugman's (1979) model of trade to multiple sectors or industries and show that, sector-by-sector, a bit of trade is worse than no trade at all. The reason is that the gains from the initiation of trade are second-order, while the welfare loss from the associated drop in varieties is...

We study vote buying by competing interest groups in a variety of electoral and contractual settings. While increasing the size of a voting body reduces its buyability in the absence of competition, we show that larger voting bodies may be more buyable than smaller voting bodies when interest...

We study a model where an employer, trying to fill a vacancy, engages in optimal sequential search by drawing from two subpopulations of candidates who differ in their quot;discourse systemsquot;: during an interview, a minority candidate with a discourse system not shared with the employer...

In the presence of competing interest groups, this paper examines how the form of vote-buying contracts affects policy outcomes. We study contracts contingent upon individual votes, policy outcomes, and/or vote shares. Voters either care about their individual votes, or about the policy outcome....

We show that too much meritocracy, modeled as accuracy of performance ranking incontests, can be a bad thing: in contests with homogeneous agents, it reduces output and isPareto inefficient. In contests with sufficiently heterogeneous agents, discouragement andcomplacency effects further reduce...

Is it better to be a big fish in a small pond or a small fish in a big pond? To find out, we study self-selection into contests among a large population of heterogeneous agents. Our simple and highly tractable model generates many testable and sometimes surprising predictions. For example: 1)...

We show that too much meritocracy, modeled as accuracy of performance ranking in contests, can be a bad thing: in contests with homogeneous agents, it reduces output and is Pareto inefficient. In contests with sufficiently heterogeneous agents, discouragement and complacency effects further...

We offer a model of "negative vote buying"--paying voters to abstain. Although negative vote buying is feasible under the open ballot, it is never optimal. In contrast, a combination of positive and negative vote buying is optimal under the secret ballot: Lukewarm supporters are paid to show up...

We study a Condorcet jury model where voters are driven by instrumental and expressive motives. We show that arbitrarily small amounts of expressive motives significantly affect equilibrium behavior and the optimal size of voting bodies. Enlarging voting bodies always reduces accuracy over some...
