• Political partisanship influences behavioral responses to governors’ recommendations for COVID-19 prevention in the United States

  Proceedings of the National Academy of Sciences · 2020 · 537 citations

  1st authorCorresponding

  Voluntary physical distancing is essential for preventing the spread of COVID-19. We assessed the role of political partisanship in individuals' compliance with physical distancing recommendations of political leaders using data on mobility from a sample of mobile phones in 3,100 counties in the United States during March 2020, county-level partisan preferences, information about the political affiliation of state governors, and the timing of their communications about COVID-19 prevention. Regre…

• Community policing does not build citizen trust in police or reduce crime in the Global South

  Science · 2021 · 117 citations

  Is it possible to reduce crime without exacerbating adversarial relationships between police and citizens? Community policing is a celebrated reform with that aim, which is now adopted on six continents. However, the evidence base is limited, studying reform components in isolation in a limited set of countries, and remaining largely silent on citizen-police trust. We designed six field experiments with Global South police agencies to study locally designed models of community policing using coo…

• The Majoritarian Threat to Liberal Democracy

  Journal of Experimental Political Science · 2021 · 99 citations

  1st authorCorresponding

  Abstract Incumbents often seek to wield power in ways that are formally legal but informally proscribed. Why do voters endorse these power grabs? Prior literature focuses on polarization. We propose instead that many voters are majoritarian , in that they view popularly elected leaders’ actions as inherently democratic – even when those actions undermine liberal democracy. We find support for this claim in two original survey experiments, arguing that majoritarians’ desire to give wide latitude…

• Forced Displacement and Asylum Policy in the Developing World

  International Organization · 2021 · 59 citations

  Abstract Little theoretical or empirical work examines migration policy in the developing world. We develop and test a theory that distinguishes the drivers of policy reform and factors influencing the direction of reform. We introduce an original data set of de jure asylum and refugee policies covering more than ninety developing countries that are presently excluded from existing indices of migration policy. Examining descriptive trends in the data, we find that unlike in the global North, for…

• Voted in, standing out: Public response to immigrants' political accession

  American Journal of Political Science · 2024-06-22 · 3 citations

  articleOpen accessSenior author

  Abstract How do dominant‐group natives react to immigrants' political integration? We argue that ethnic minority immigrants winning political office makes natives feel threatened, triggering animosity. We test this dynamic across the 2010–2019 UK general elections, using hate crime police records, public opinion data, and text data from over 500,000 regional and local newspaper articles. While past work has not established a causal relationship between minorities' political power gains and domin…
