Which budgetary institutions result in efficient provision of public goods? We analyze a model with two parties bargaining over the allocation to a public good each period. Parties place different values on the public good, and these values may change over time. We model a budgetary institution...

The so-called "paradox of voting" is major anomaly for rational choice theories of elections. If voting is costly and citizens are rational then large electorates the expected turnout would be small, for if many people voted the chance of anyone being pivotal would be too small to make the act...

This paper presents a dynamic model of election, government formation, and legislation in a parliamentary democracy with proportional representation in which the policy chosen in one period becomes the status quo for the next period. The electorate votes strategically by taking into account the...

Activist NGOs have increasingly foregone public politics and turned to private politics to change the practices of firms and industries. This paper focuses on private politics, activist strategies, and nonmarket strategies of targets. A formal theory of an encounter between an activist...

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...
