We study communication in committees selecting one of two alternatives when consensus is required and agents have private information about their preferences. Delaying the decision is costly, so a form of multiplayer war of attrition emerges. Waiting allows voters to express the intensity of...

We study Colonel Blotto games with sequential battles and a majoritarian objective. For a large class of contest success functions, the equilibrium is unique and characterized by an even split: Each battle that is reached before one of the players wins a majority of battles is allocated the same...

We study dynamic sequential majoritarian campaigns between two players. The winner of the campaign is whomever wins the majority of individual battles. The resource being expended is determined exogenously to the campaign and has no scrap value. We demonstrate, in a fairly general environment,...

A conclave is a voting mechanism in which a committee selects an alternative by voting until a sufficient supermajority is reached. We study experimentally welfare properties of simple three-voter conclaves with privately known preferences over two outcomes and waiting costs. The resulting game...

When are political institutions stable? When do they tend toward reform? This paper examines a model of dynamic, endogenous institutional change. We introduce the class of dynamic political games (DPGs), dynamic games in which the political aggregation rules used at date t+1 are chosen by the...

In this chapter, we assess recent contributions of computational models to the study of politics. We focus primarily on agent-based models developed by economists and political scientists. These models address collective action problems, questions related to institutional design and performance,...

We study Colonel Blotto games with sequential battles and a majoritarian objective. For a large class of contest success functions, the equilibrium is unique and characterized by an even split: Each battle that is reached before one of the players wins a majority of battles is allocated the same...

Criminal groups use violence strategically to manipulate the behavior of victims and bystanders. At the same time, violence is a stimulus that causes fear, which also shapes people’s reactions. Taking advantage of the randomness in the timing of antipersonnel landmine accidents in Colombia, as...

The aim of this note is to discuss previously unnoticed stability properties of majoritarian decision making. We study collective decisions problems that can be described in terms of symmetric games satisfying various regularity conditions. We show that restricting the objecting power to...

We study vote trading among U.S. Congress members. By tracking roll-call votes within bills across five legislatures and politicians' personal connections made during the school years, we document a propensity of connected legislators to vote together that depends on how salient the bill is to...
