Climate change is a global "free rider" problem because significant abatement of greenhouse gases is an expensive public good requiring international cooperation to apportion compliance among states. But it is also a global "free driver" problem because geoengineering the stratosphere with...

We distinguish between three sets of rights – property rights, political rights, and civil rights – and provide a taxonomy of political regimes. The distinctive nature of liberal democracy is that it protects civil rights (equality before the law for minorities) in addition to the other two....

We study the information aggregation properties of unanimous voting rules in the laboratory. In line with theoretical predictions, we find that majority rule with veto power dominates unanimity rule. We also find that the strategic voting model is a fairly good predictor of observed subject...

It is widely believed that politicians allocate public resources in ways to maximize political gains. But what is less clear is whether this comes at a cost to welfare; and if so, whether alternative electoral rules can help reduce these costs. In this paper, we address both of these questions by...

This paper studies the political determinants of inequality in government interventions under the majoritarian and proportional representation systems. Using a model of electoral competition with targetable government intervention and heterogeneous localities, we uncover a novel relative...

We study optimal policy experimentation by a committee. We consider a dynamic bargaining game in which committee members choose either a risky reform or a safe alternative each period. When no redistribution is allowed the unique equilibrium outcome is generically inefficient. When...

Storable Votes and Quadratic Voting are voting systems designed to account for voters' intensity of preferences. We test their performance in two samples of California residents using data on four initiatives prepared for the 2016 California ballot. We bootstrap the original samples and generate...

We study the properties of the group-based model of voting in elections with more than two candidates. We consider two of the most widely used electoral rules around the world: plurality and majority runoff. We fully characterize the set of equilibria under both rules and identify the features...

The paper studies a voting scheme where members of a committee voting sequentially on a known series of binary proposals are each granted a single extra bonus vote to cast as desired - a streamlined version of Storable Votes. When the order of the agenda is exogenous, a simple sufficient...

For voters with quot;socialquot; preferences, the expected utility of voting is approximately independent of the size of the electorate, suggesting that rational voter turnouts can be substantial even in large elections. Less important elections are predicted to have lower turnout, but a...
