World democracies widely differ in electoral rules, as well as in legislative, executive or legal institutions. Different institutional environments induce different mappings from electoral outcomes to the distribution of power. We explore how these mappings affect voters' participation to an...

We study the role of perceived threats from cultural diversity induced by terrorist attacks and a salient criminal event on public discourse and voters' support for far-right parties. We first develop a rule which allocates Twitter users in Germany to electoral districts and then use a machine...

Are ordinary citizens or political party leaders better positioned to select candidates? While the American primary system lets citizens choose, most democracies rely instead on party officials to appoint or nominate candidates. The consequences of these distinct design choices are unclear:...

Since 2000, ten states have enacted strict voter identification laws, which require that voters show identification in order for their votes to count. While proponents argue these laws prevent voter fraud and protect the integrity of elections, opponents argue they disenfranchise low-income and...

In this paper we document the impact of immigration at the regional level on Europeans' political preferences as expressed by voting behavior in parliamentary or presidential elections between 2007 and 2016. We combine individual data on party voting with a classification of each party's...

Climate change partisanship is reflected in residential choice. Comparing individual occupants at properties in the same zip code with similar elevation and proximity to the coast, registered republicans (democrats) are more (less) likely than independents to own houses exposed to sea level rise...

We study the contribution of economic conditions to the success of the first avowedly nativist political party in the United States. The Know-Nothing Party gained control of a number of state governments in the 1854-1856 elections running on a staunchly anti-Catholic and anti-Irish platform. Our...

The current polarization of elites in the U.S., particularly in Congress, is frequently ascribed to the emergence of cohorts of ideologically extreme legislators replacing moderate ones. Politicians, however, do not operate as isolated agents, driven solely by their preferences. They act within...

Political partisanship is strongly correlated with attitudes and behavior, but it is unclear from this pattern whether partisan identity has a causal effect on political behavior and attitudes. We report the results of a field experiment designed to investigate the causal effect of party...

We estimate the impact of a large anti-poverty cash transfer program, the Uruguayan PANES, on political support for the government that implemented it. Using the discontinuity in program assignment based on a pre-treatment eligibility score, we find that beneficiary households are 11 to 14...
