Biased beliefs affect real-world decisions, including political solutions to societal challenges. One crucial example is environmental policy: people tend to underestimate the incentive effect of Pigouvian policies. Addressing biased beliefs at scale is then paramount. In the days leading up to...

We study how shocks to voting costs affect electoral turnout. Individuals whose polling place is relocated face changes to their cost of voting in person due to altered distance and unfamiliarity with the new polling place. Using address-level and precinct-level data, we find that polling place...

We empirically assess whether hindsight bias has consequences on how citizens evaluate their political actors. Using an incentivized elicitation technique, we demonstrate that people systematically misremember their past policy preferences regarding how to best fight the Covid-19 pandemic. At...

Social media are at the center of countless debates on polarization, misinformation, and even the state of democracy in various parts of the world. An essential feature of social media is the ranking algorithm that determines how content is presented to the users. This paper studies the dynamic...

We conduct a survey experiment among 18,000 respondents in Germany to examine the determinants of support for rent control policies. Highlighting undesirable price and supply effects lowers respondents' agreement with rent control, while pointing out that it can prevent displacement of...

How do political preferences and voting behaviors respond to information coming from abroad? Focusing on the international migration network, I document that opinion changes at the origins spill over to 1st- and 2nd-generation immigrants abroad. Local diasporas, social media, and family ties to...

In this study, we propose a novel approach to detect supply-side media bias, independent of external factors like ownership or editors' ideological leanings. Analyzing over 100,000 articles from The New York Times (NYT) and The Wall Street Journal (WSJ), complemented by data from 22 million...

We study the effects of information on attitudes towards inheritance taxation using survey experiments fielded in Germany. We show that information about tax allowances increases demand for higher taxes and shifts public opinion from favoring abolition to supporting the tax. Effects are...

This paper studies how political competition can lead candidates to strategically increase the salience of specific issues, in order to influence voting decisions of marginal groups, with non trivial consequences for turnout rates. In my setup issues differ in their divisiveness, to be defined...

In a country with weak institutional constraints on the executive, the real power might belong to the government bureaucracy rather than to an autocratic leader. We combine the Aghion-Tirole definition of formal and real authority with the Barro-Ferejohn model of political agency to study the...
