We study games played between groups of players, where a given group decides which strategy it will play through a vote by its members. When groups consist of two voting players, our games can also be interpreted as network-formation games. In experiments on Stag Hunt games, we find a stark...

We analyze dynamic electoral competition policy changes. The costs of changing a policy increase with the extent of the shift and generate an incumbency advantage. We characterize the dynamics of Markov equilibria in terms of history and party polarization, and analyze how policies are...

How can a principal (employer or voter) induce an agent (worker or politician) to choose the 'right' actions if risky actions reveal the agent's decision-making competence and only dismissal can be used as an incentive instrument? The principal wishes to replace incompetent agents, but...

In this paper we analyze the problem of whether and/or when to replace a leader (agent) when no monetary rewards are available, and it is the leader's competence rather than effort that is being evaluated. The only decisions that the leader takes over time are whether to undertake risky but...

We analyze the optimal length of political terms (equivalently, the optimal frequency with which elections should be held) when the candidates of two polarized parties compete for office and the median voter shifts over time. Office-holders determine policy and experience persistent random...

For groups that must make several decisions of similar form, we define a simple and general mechanism that is designed to promote social efficiency. The mechanism links the various decisions by forcing agents to budget their representations of preferences so that the frequency of preferences...

A collective action or revolt succeeds only if sufficiently many people participate. We study how potential revolutionaries' ability to coordinate is affected by what they learn from different sources. We first examine how people learn about the likelihood of a revolution's success by talking to...

We study all-pay auctions (or wars of attrition), where the highest bidder wins an object, but all bidders pay their bids. We consider such auctions when two bidders alternate in raising their bids and where all aspects of the auction are common knowledge including bidders.valuations. We analyze...

Negotiation involves determining not only an agreement's price, but also its content, which typically has many aspects. We model such negotiations and provide conditions under which negotiation leads to efficient outcomes, even in the face of substantial asymmetric information regarding the...
