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...

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...

Social media platforms are often credited with empowering grassroots movements in the pursuit of political freedoms. In this paper, we show how social media can also be exploited by political elites to undermine democratic institutions, using the January 6th, 2021 Capitol insurrection as a case...

Democratic societies depend on citizens following rules even when those rules are set by political opponents. Rising polarization may threaten this behavior. We test the impact of polarization on rule compliance in the United States across three pre-registered waves (May and November 2024; April 2025; n...

A growing literature concerns the role of symbolic politics, including how political parties benefit electorally from politicizing the past, a strategy which should be more effective in localities with physical memories of the past. We test this argument by studying the effect of the local...

In an important and much cited study, Pettersson-Lidbom (2008) identifies significant left-wing majority coalition effects on economic outcomes for Swedish local governments, 1974-1994. We first replicate the original study and then extend the original research by applying Pettersson-Lidbom's...

Why are inefficient policies popular? One explanation is incomplete voter information. Evidence from survey experiments in Argentina points instead to inattention. The experiments explore voter evaluations of two anti-inflation policies, price controls and limits on monetary emission....

Das Gebäudeenergiegesetz (GEG), umgangssprachlich auch "Heizungsgesetz" genannt, sorgte in den letzten Jahren für viele Diskussionen in Öffentlichkeit, Medien und Politik. Die meisten Zeitungen berichteten ausgiebig über den Entwurf der GEGNovellierung, wobei er überwiegend negativ bewertet...

Auch 35 Jahre nach der deutschen Einheit wird in Politik und Öffentlichkeit weiterhin intensiv darüber diskutiert, welche Unterschiede zwischen Ost und West bestehen und wie weit das Land tatsächlich zusammengewachsen ist. Besonders deutlich treten diese Differenzen im politischen...

A new party has entered the German political landscape: The Bündnis Sahra Wagenknecht (BSW). After years of debate that her former party, The Left, had become "too liberal," one of Germany's most prominent politicians, Sahra Wagenknecht, founded her new party in January 2024. The BSW is...

This paper investigates whether political partisanship and political narratives affect voters' opinions about public finances. In a novel survey experiment, we test the causal effect of pro-consolidation and pro-public investment narratives used in German general election campaigns on...

This paper investigates the causal effect of the term length of political executives on economic policy outcomes. To establish causality, we exploit the staggered adoption of four-year terms for governors across US states, using data for the period 1937-2008. We find that increasing governors'...

This study contests the emerging consensus that the educational realignment in voting behavior is centered on non-economic policies. Leveraging comprehensive post-election surveys and party manifesto data, I examine voter responses to previously underexplored dimensions of economic policy - most...

Despite a comparatively strong economic outlook in 2024, American voters chose Donald Trump. Does this mean voters no longer care about the economy? This article argues that they do - but not always in the way predicted by conventional theory. By contrasting "Bidenomics" in the United States...

We investigate the determinants of states' policy capacity, defined as the ability of states to craft effective policies. Our model shows that the interaction between politicians' implementation decisions and bureaucrats' motivation to design effective policies can lead to the coexistence of...

This paper proposes an explanation of variations in anti-system voting in European democracies. It tests the hypothesis that younger voters are the main constituent of anti-system parties, conditional on the type of welfare regime of the society they live in. We show that when economic resources...

We show how exposure to partisan peers, under conditions requiring high stakes cooperation, can trigger the breakthrough of novel political beliefs. We exploit the largescale, exogenous assignment of soldiers from each of 34,947 French municipalities into line infantry regiments during World War...

We study whether exposure to social movements campaigning against income and gender income inequality shifts individual beliefs about inequality, reshapes preferences for redistribution, and translates into political participation in the UK. Since the Great Recession of the 2010s, the UK has...

This paper investigates a voting model in which two candidates strategically compete in a winner-take-all election. Voters consider both the spatial dimension of policy positions and other attributes, or valence, of each candidate. Candidates are policy motivated and endeavor to make specific...

Many socially desirable policies are not implemented because of their ex-ante unpopularity, but this unpopularity may be overcome through experience with the policy. In this paper, we examine how opposition to carbon pricing in the state of Washington turned into support after voters experienced...
