• Conjoint Survey Experiments

  Cambridge University Press eBooks · 2021 · 225 citations

  Conjoint survey experiments have become a popular method for analyzing multidimensional preferences in political science. If properly implemented, conjoint experiments can obtain reliable measures of multidimensional preferences and estimate causal effects of multiple attributes on hypothetical choices or evaluations. This chapter provides an accessible overview of the methodology for designing, implementing, and analyzing conjoint survey experiments. Specically, we begin by detailing a new subs…

• Using Conjoint Experiments to Analyze Election Outcomes: The Essential Role of the Average Marginal Component Effect

  Political Analysis · 2022 · 113 citations

  Abstract Political scientists have increasingly deployed conjoint survey experiments to understand multidimensional choices in various settings. In this paper, we show that the average marginal component effect (AMCE) constitutes an aggregation of individual-level preferences that is meaningful both theoretically and empirically. First, extending previous results to allow for arbitrary randomization distributions, we show how the AMCE represents a summary of voters’ multidimensional preferences…

• The Rise of Trump, The Fall of Prejudice? Tracking White Americans’ Racial Attitudes Via A Panel Survey, 2008–2018

  Public Opinion Quarterly · 2020 · 84 citations

  1st authorCorresponding

  Abstract In his campaign and first few years in office, Donald Trump consistently defied contemporary norms by using explicit, negative rhetoric targeting ethnic/racial minorities. Did this rhetoric lead White Americans to express more or less prejudiced views of African Americans or Hispanics, whether through changing norms around racial prejudice or other mechanisms? We assess that question using a thirteen-wave panel conducted with a population-based sample of Americans between 2008 and 2018.…

• The rise of and demand for identity‐oriented media coverage

  American Journal of Political Science · 2024-07-01 · 13 citations

  articleOpen access1st authorCorresponding

  Abstract While some assert that social identities have become more salient in American media coverage, existing evidence is largely anecdotal. An increased emphasis on social identities has important political implications, including for polarization and representation. We first document the rising salience of different social identities using natural language processing tools to analyze all tweets from 19 media outlets (2008–2021) alongside 553,078 URLs shared on Facebook. We then examine one p…

• Unsubscribed and undemanding: Partisanship and the minimal effects of a field experiment encouraging local news consumption

  American Journal of Political Science · 2024-03-19 · 13 citations

  article1st authorCorresponding

  Abstract Local newspapers convey extensive subnational political information but have dwindling audiences. In a nationalized and polarized information environment, can online interventions increase state/local news consumption and with what effects? We explore this question via a preregistered experiment randomizing Pennsylvania residents ( n = 5059) to staggered interventions encouraging news consumption from leading state newspapers. A total of 2529 individuals were offered free online subscri…
