We experimentally test competing theories of three-player majoritarian bargaining models with fixed, known disagreement values. Subjects are randomly assigned to three roles: a proposer and two types of voters. Each role is randomly assigned a disagreement value, i.e. a given amount of money...

Models with adaptive agents have become increasingly popular in computational sociology (e.g. Macy 1991, Macy and Flache 2002). In this paper we show that at least two important kinds of such models lack empirical content. In the first type players adjust via reinforcement learning: they adjust...

We provide a definition of institutionalism and a schematic account that distinguishes between institutional theories (in which institutions are exogenous) and theories of institutions (in which some, but necessarily not all, institutions are endogenous). Our primary argument is that...

Our main goal is to quantify the returns to a career in the United States Congress. We specify a dynamic model of career decisions of a member of Congress and estimate this model using a newly collected dataset. Given estimates of the structural model, we assess reelection probabilities,...
