We provide causal evidence that immigration has contributed to the polarization of American politics. Using an ancestry-based shift-share instrument, we study immigration flows into U.S. counties between 1992 and 2016. Counties exposed to larger immigrant inflows become more polarized both in...

Kendall, Chad - 2026

I study how political parties affect representation in the U.S. House. To do so, I account for party pressure on the votes of members in an otherwise standard spatial model that uses roll call voting patterns to identify member ideologies. I simultaneously estimate voter ideologies from survey...

Boeri, Tito; Nikiforova, Nina; Tabellini, Guido Enrico - 2026

We study the communication strategies on Twitter/X of 367 political leaders in 21 countries, focusing on electoral competition between populists and non-populists. We measure polarization by the ease with which the leader can be classified as populist or not, conditional on his tweet. We find...

Radical Right (RR) political parties have become increasingly radicalized on immigration across many developed countries. We study whether exposure to slanted (i.e., one-sided) news shifts policy views of RR voters on immigration in Austria. In an online experiment, participants received slanted...

Voter Preferences, party politics and environmental policy reform

Adler, Martin; Peer, Stefanie; Russo, Antonio - 2026

Policymakers frequently implement environmental policies that are less ambitious than what voters would prefer. We document this gap using findings from previous research as well as evidence from climate policy in Austria's transport sector. To account for this pattern, we develop a model in...

Majority lost : global evidence and field experiments on electoral miscoordination

Capozza, Francesco; Durante, Ruben; George, Siddharth Eapen - 2026

Voters in multiparty systems often fail to coordinate on majority-preferred parties. Using constituency-level election data linked to party-ideology measures across 96 countries, we show that in 20–30% of multiparty elections since 1940 the Condorcet winner does not win, and in roughly 10% the...

Moral characters : social media and elections in the US

Grillo, Edoardo; Morales, Juan S.; Moresi, Alessandra - 2026

We compile a new dataset covering over 4,000 Twitter accounts and almost five million tweets by US House candidates over 2008-2018. We document several descriptive facts: social media use...
