Many political commentators diagnose an increasing polarization of the U.S. electorate into two opposing camps. However, in standard spatial voting models, changes in the political preference distribution are irrelevant as long as the position of the median voter does not change. We show that...

We introduce a general framework in which politicians choose a (possibly infinite) sequence of binary policies. The two competing candidates are exogenously committed to particular actions on a subset of these issues, while they can choose any policy for the remaining issues to maximize their...

We introduce a framework of electoral competition in which voters have general preferences over candidates' characteristics and policies. Candidates' immutable characteristics (such as gender, race or previously committed policy positions) are exogenously differentiated, while candidates can...

We develop a formal model in which the government provides public goods in different policy fields for its citizens. We start from the basic premise that two office-motivated candidates have differential capabilities in different policy fields, and compete by proposing how to allocate government...

How does ideological polarization on non-economic matters influence the size of government? We analyze this question using a differentiated candidates framework: Two office-motivated candidates differ in their (fixed) ideological position and their production function for public goods, and...

A central contested question is whether this diagnosis is actually true, and if so, what is the underlying cause. We develop a model that relates the...
