From the regulation of sports to lawmaking in parliament, in many situations one group of people (“agents”) make decisions that affect the payoffs of others (“principals”) who may offer action-contingent transfers in order to sway the agents' decisions. Prat and Rustichini (2003)...

We study both theoretically and experimentally the set of Nash equilibria of a classical one-dimensional election game with two candidates. These candidates are interested in power and ideology, but their weights on these two motives are not necessarily identical. Apart from obtaining the well...

We examine implications of a society's cultural emphasis on moral sentiments. Entrepreneurs and investors interact in a game that entails both adverse selection and moral hazard; entrepreneurs may attempt to breach their contracts and expropriate investors. An agent is born into a particular...

In a multi-stage contest known as a two-player race, players display two fundamental behaviors: (1) the laggard will make a last stand in order to avoid the cost of losing; and (2) the player who is ahead will defend his lead if it is threatened. Last stand behavior, in particular, contrasts...

We study experimentally the effects of cost structure and prize allocation rules on the performance of rent-seeking contests. Most previous studies use a lottery prize rule and linear cost, and find both overbidding relative to the Nash equilibrium prediction and significant variation of...

We offer complete characterizations of the equilibrium outcomes of two prominent agenda voting institutions that are widely used in the democratic world: the amendment, also known as the Anglo-American procedure, and the successive, or equivalently the Euro-Latin procedure. Our axiomatic...

We report on an experiment comparing compulsory and voluntary voting institutions in a voting game with common preferences. Rational choice theory predicts sharp differences in voter behavior between these two institutions. If voting is compulsory, then voters may find it rational to vote...

We study an election with two perfectly informed candidates. Voters share common values over the policy outcome of the election, but possess arbitrarily little information about which policy is best for them. Voters elect one of the candidates, effectively choosing between the two policies...

In a common-values election where voters receive a signal about which candidate is superior, suppose there is a small amount of uncertainty about the likelihood of the signal's outcome, holding fixed the correct candidate. Once this uncertainty is resolved, the signal is i.i.d. across agents....

We consider the optimization problem of a campaign trying to win an election when facing aggregate uncertainty, where agents' voting probabilities are uncertain. Even a small amount of uncertainty will in a large electorate eliminate many of counterintuitive results that arise when voting...
