Race, Ethnicity, and Immigration

The Rise of and Demand for Identity-Oriented Media Coverage

American Journal of Political Science, Conditionally Accepted. Co-authored with Yphtach Lelkes and Samuel Wolken.

This paper examines whether news that has clear social identity cues is more likely to generate engagement on social media sites such as Twitter and Facebook–and whether such news content is increasingly common in the period from 2008-2021. [SSRN] [Data and Code] [Ungated]

Differently Divisive: Sexism, Racial Resentment, and Voter Support for Candidates with Incongruent Views

Journal of Politics, Conditionally Accepted. Co-authored with Ryan Bell, Gabriel Borelli, Rafaela Dancygier, and Jeremy Roth.

This paper uses a 2019-2020 panel with a conjoint experiment and a 2023 follow-up experiment to investigate how Americans respond to candidates who make different statements on race and gender. [SSRN]

Economic Strain Does Not Reduce Support for Ukrainian Refugees

Co-authored with Will Halm, Krzysztof Krakowski, and Nicholas Sambanis. SSRN Working Paper 4585580.

This paper uses panels in Poland and Germany in 2022-2023 to demonstrate the stability of pro-refugee and pro-Ukraine attitudes in both countries as the economic strains from Russia’s 2022 invasion of Ukraine grew.

Personal Economic Shocks and Public Opposition to Immigration

British Journal of Political Science, Forthcoming. Co-authored with Yotam Margalit and Omer Solodoch.

Employing a population-based panel of Americans 2007-2020, this research demonstrates that personal negative economic shocks such as losing a job or income lead to increased opposition to unauthorized immigration. [SSRN]

Increased Fox News Viewership is Not Associated with Heightened Anti-Black Prejudice

Co-authored with Yphtach Lelkes and Samuel Wolken. SSRN Working Paper 4420947.

This paper uses a long-running, population-based panel to estimate the associations between changing Fox News viewership and changing levels of anti-Black prejudice and immigration attitudes.

The Surprising Stability of Asian Americans’ and Latinos’ Partisan Identities in the Early Trump Era

Journal of Politics, 2023, 85(4):1321-1335. Co-authored with Cheryl Kaiser  and Efrén O. Pérez. SSRN Working Paper, 3840922.

The Rise of Trump, the Fall of Prejudice? Tracking White Americans’ Racial Attitudes 2008-2018 via a Panel Survey

Public Opinion Quarterly, 2020, 84(1):119-140; SSRN Working Paper 3378076, co-authored with Samantha Washington [SSRN]

Using a panel survey which tracks racial prejudice from 2008 to 2018, this research shows that different measures of prejudice declined or at least did not increase in the first two years of Trump’s presidency. [Media: FiveThirtyEight, Washington Post, Philadelphia Inquirer, Spectator]

Past Place, Present Prejudice: The Impact of Adolescent Racial Context on White Racial Attitudes

Journal of Politics, 2020, 82(2):529-542; SSRN Working Paper 2799347, co-authored with Seth Goldman

Extensive research suggests that non-Hispanic whites living near African Americans have higher levels of prejudice. In this paper, we show that where people lived as adolescents–not where they live as adults–predicts their levels of prejudice. [Appendix] [Data] [SSRN]

The Muted Consequences of Correct Information on Immigration

Journal of Politics, 2019 81(1):315-320 ; SSRN Working Paper 2798622, co-authored with John Sides and Jack Citrin

People who over-estimate the share of immigrants in the U.S. tend to be more opposed to immigration. In this paper, we use four experiments to show that providing accurate information about actual immigrant population shares does little to dampen opposition to immigration.

Does Perceiving Discrimination Influence Partisanship among U.S. Immigrant Minorities? Evidence from Five Experiments

Journal of Experimental Political Science, 2019 7(2):112-136; SSRN Working Paper 3236348, co-authored with Cheryl Kaiser, Efrén Pérez, Sara Hagá, Corin Ramos, and Michael Zárate

Using five experiments with Asian American and Latino subjects, this paper reports no evidence of a causal link between perceptions of group-targeted discrimination and party-related attitudes. [Ungated, SSRN] [Data]

When Can Exemplars Shape White Racial Attitudes? Evidence from the 2012 U.S. Presidential Campaign

International Journal of Public Opinion Research, 2019 31(4):649-668; SSRN Working Paper 3268012, co-authored with Seth Goldman

Prior research has shown that exposure to Barack Obama in 2008 reduced anti-Black stereotypes among whites–but did he have the same effect in 2012, when we was a more familiar and partisan figure? This article shows even in the polarized environment of 2012, exposure to Obama reduced anti-Black prejudice. [Ungated]

Out of Context: The Unexpected Absence of Spatial Variation in U.S. Immigrants’ Perceptions of Discrimination

Politics, Groups, and Identities, 2016, 4(3):363-92, co-authored with Jonathan Mummolo, Victoria Esses, Cheryl Kaiser, Helen Marrow, and Monica McDermott

Both scholarship and journalism lead us to expect that immigrants will experience different levels of discrimination depending on where within the U.S. they settle.  To the contrary, this paper finds a striking lack of spatial variation in first-generation immigrants’ perceptions of discrimination, and discusses the implications of its results.

The Hidden American Immigration Consensus: A Conjoint Analysis of Attitudes toward Immigrants

American Journal of Political Science, 2015, 59(3):529-548, co-authored with Jens Hainmueller

This paper uses conjoint analysis, a tool from marketing, to test a range of hypotheses about Americans’ attitudes toward immigrants.  Drawing on a two-wave Knowledge Networks survey, it demonstrates that Americans view educated immigrants in high-status jobs favorably, while they view those who lack plans to work, have previously entered without authorization, or do not speak English unfavorably.  I summarized this research at The Washington Post’s Wonkblog here.

The Upside of Accents: Language, Skin Tone, and Attitudes toward Immigration

British Journal of Political Science, 2015, 45(3):531-557; SSRN Working Paper 1879965

Do immigrants who speak Spanish or have darker skin tones provoke more support for restricting immigration?  This paper uses two population-based survey experiments to demonstrate that they do not.  Instead, an immigrant speaking with a pronounced accent induces more pro-immigration attitudes, likely because the accent is seen as a signal of his desire to assimilate.  I summarized this research on The Monkey Cage here. [Online Appendix] [Data]

Public Attitudes towards Immigration

Annual Review of Political Science, 2014, 17:225-249, co-authored with Jens Hainmueller

This review summarizes and then discusses just under 100 studies of immigration attitudes undertaken over the past two decades. Consistently, immigration attitudes show little evidence of being strongly correlated with personal economic circumstances. Instead, immigration attitudes are shaped by sociotropic concerns about national-level impacts, whether those impacts are cultural or economic.

One Language, Two Meanings: Partisanship and Responses to Spanish

Political Communication, 2014, 31(3):421-455

The Spanish language is a flashpoint in discussions about immigration.  Do brief encounters with Spanish shape attitudes toward immigration and integration?  Coupling a survey experiment with voting data from California, this paper shows that Spanish induces different responses among Republicans and Democrats–and that its use on ballots can influence voting patterns as well. [Ungated, SSRN]

See No Spanish? Language, Local Context, and Attitudes toward Immigration

Politics, Groups, and Identities, 2014, 2(1):35-51, co-authored with Van C. Tran and Abigail Fisher Williamson

This paper explores whether brief exposures to Spanish can influence Americans’ immigration attitudes–and uses multiple experiments to show that the impact hinges on people’s prior exposure to Spanish. For those who hear Spanish frequently, even a subtle exposure to written Spanish induces anti-immigration attitudes. [Earlier Version] [Data]

Flooded Communities: Explaining Local Reactions to the Post-Katrina Migrants

Political Research Quarterly, 2012, 65(2):443-459

This paper uses the post-Katrina migration as a source of exogenous variation to explore the impact of changing demographics on a variety of political attitudes and behaviors.  It shows that Baton Rouge and Houston respondents to the Katrina evacuees in different ways, with Baton Rouge residents growing increasingly opposed to public benefits and Houston residents becoming increasingly concerned about crime.   [Data]  [Award: Best Poster, 2007 Summer Meeting of the Society for Political Methodology]

Translating into Votes: The Electoral Impact of Spanish-Language Ballots

American Journal of Political Science, 2011, 55(4):814-830

This manuscript uses two data sets to examine the impact of Spanish-language ballots. Exploiting a sharp discontinuity in the Voting Rights Act, it demonstrates that Spanish-language ballots increased turnout among Spanish speakers, and that they decreased opposition to bilingual education in California’s 1998 Proposition 227.  This research was discussed by Voice of America News and New America Media.

National Debates, Local Responses: The Origins of Local Concern about Immigration in the U.K. and the U.S.

British Journal of Political Science, 2011, 41(3):499-524

The political impact of people’s neighborhoods can change quite dramatically depending on what topics are salient in national politics. This paper uses panel data from the U.K. to demonstrate that living near immigrants shapes concern about immigration primarily when the issue is prominent in national debates. Survey data from the U.S. reinforce this claim.  [Online Appendix]

The Limited Local Impacts of Ethnic and Racial Diversity

American Politics Research, 2011, 39(2):344-379

Past research contends that ethnic and racial diversity dampens spending on a variety of public goods in U.S. cities. This paper takes a second look, using the most extensive data set on city spending from 1950 to 2002 available to date. It shows that the relationship between diversity and public goods is far weaker than previously suspected. In recent years, the only consistent influence has been to increase criminal justice spending. This post at Wonkblog draws on this research. [Supplemental Information] [Data]

Politicized Places: Explaining Where and When Immigrants Provoke Local Opposition

American Political Science Review, 2010, 104(1):40-60

Testing a novel theory of neighborhood effects, this paper shows that immigrants are construed as threatening under two conditions: when immigrants suddenly arrive in a community and when national rhetoric or frames are available to politicize their arrival.  This article was covered in Emerging Issues and the New York Times. [Data]

The Diversity Discount: How Increasing Ethnic and Racial Diversity Dampens Support for Tax Increases

Journal of Politics, 2009, 71(1):160-177

Using a unique data set on tax votes in Massachusetts communities, this paper demonstrates that sudden increases in diversity can dampen the provision of public goods by reducing the number of long-term projects put before voters.  The article was discussed in the Boston Globe and The New York Times as well.

British Journal of Political Science. 2023. 53(1):297-307 . SSRN Working Paper 3840201, 2021

This paper uses a population-based panel survey to investigate changes in public opinion 2007 to 2020.

The Exaggerated Life of Death Panels: The Limited but Real Influence of Elite Rhetoric in the 2009-2010 Health Care Debate

Political Behavior, 2018, 40(3):681-709; SSRN Working Paper 20163769

Did frames like those about “death panels” influence public opinion on health care reform during the contentious 2009-2010 debates on the issue?  This paper applies automated content analysis to press releases, television appearances, and open-ended survey questions to address that question.  It illustrates the limits of framing effects, as the public’s core reasons for supporting and opposing the Affordable Care Act were evident in its language even before health care became a salient issue.  I summarized elements of this research in the Washington Post and on The Monkey Cage.

Assessing the Breadth of Framing Effects

Quarterly Journal of Political Science, 2017, 12(1):37-57; SSRN Working Paper 2863930; co-authored with Jonathan Mummolo

When citizens are exposed to an argument on one issue, does it influence their attitudes on others? This research uses a novel, population-based survey experiment to show that the answer is largely “no”–framing effects tend to be constrained to the issues discussed explicitly by the political rhetoric.

Does Newspaper Coverage Influence or Reflect Public Perceptions of the Economy?

Research and Politics, 2017, 4(4):1-7; SSRN Working Paper 3025144; co-authored with Eunji Kim and Soojong Kim

Does the tone of newspaper coverage about the economy systematically lead or lag public perceptions of economic performance? This paper considers evidence from nearly half a million newspaper articles and television transcripts from 24 media outlets, along with 246,000 responses to the Survey of Consumer Attitudes. Especially for national outlets like the New York Times and Washington Post, the tone of coverage shifts after public opinion, an observation which places important limits on the extent to which these national outlets are actively shaping public opinion.

This paper assesses the effect of a change in voter ID policies in Virginia implemented between 2013 and 2014. The evidence indicates that the strict photo identification requirements did not seem to deter substantial numbers of Virginia voters from casting ballots in 2014, possibly because of outreach efforts that accompanied its implementation.

Political Behavior, 2016, 38(3):713-746; SSRN Working Paper 2307631; co-authored with Michael Bailey and Todd Rogers

Does inter-personal persuasion work in a presidential campaign?  In this paper, we evaluate a large-scale field experiment in which 56,000 Wisconsin voters were randomly assigned to persuasive contacts through canvassing, phone calls, and mail.  The results indicate a backlash, as canvassed voters were less likely to complete a follow-up survey and less likely to support the candidate backed by the campaign.  I summarized this research at The Washington Post’s Wonkblog here.

No Wilder Effect, Never a Whitman Effect: When and Why Polls Mislead about Black and Female Candidates

Journal of Politics, 2009, 71(3):769-781

Analysts have commonly discussed the “Wilder effect,” the gap between how black candidates poll and how they perform on election day. Testing these claims on all elections for Senator or Governor from 1989 to 2006, this paper finds that the Wilder effect disappeared for black candidates by the mid-1990s. This article was discussed in media outlets including ABC News, Newsweek, The New York Times, The Portland Press-Herald, The San Francisco Chronicle, The Washington Post, The New York Daily News, Time Magazine, and Science.  [Data]

Whose Economy?  Perceptions of Economic Performance During Unequal Growth

Public Opinion Quarterly, 2012, 76(1):50-70.  SSRN Working Paper 1736742

Americans’ perceptions of economic performance are a powerful influence on Presidential approval and candidate choice, but past research rarely considers what influences these perceptions.  It also has not considered how rising income inequality has shaped economic perceptions.  In past work, snapshots from elections create the impression that these assessments of economic performance are influenced only by income growth among the wealthy. Examining more than 215,000 respondents over three decades, however, we learn that income growth among the poor is frequently more influential.  [Data]

Partisan Reinforcement and the Poor: The Impact of Context on Attitudes toward Poverty

Social Science Quarterly, 2009, 90(3):744-764

Can contextual factors shape attitudes toward the poor? Synthesizing racial and political theories of contextual effects, this paper explores attitudes about who is to blame for poverty. It demonstrates that both an area’s racial composition and its partisan composition can influence respondents’ views about why people are poor. [Code]

Racial Contexts’ Enduring Influence on Attitudes toward Poverty

Social Science Quarterly, 2009, 90(3):770-776

A reply, this article extends the original evidence that racial contexts–and not certain other contextual measures–shape attitudes toward poverty. It then presents new evidence from an exogenous demographic shock to reinforce the claim that racial contexts shape views of the poor.

Economic Voting in Big-City U.S. Mayoral Elections

Political Science Research and Methods, 2018, 6(4):697-714; SSRN Working Paper 2567294, co-authored with Lindsay M. Pettingill

At the presidential level, we know a lot about why voters support incumbents–but we know far less about retrospective voting in mayoral elections. Using a novel data set with 341 mayoral elections, the paper shows that incumbent mayors suffer at the ballot box when their city’s unemployment rate is high relative to the nation’s. I also summarized this research at FiveThirtyEight. [Data]

American Politics Research, 2012, 40(4):665-700, SSRN Working Paper 1632390, co-authored with Katherine T. McCabe

Mayoral elections between black and white candidates frequently generate charged rhetoric.  But do black mayoralties pursue different fiscal or employment policies once elected?  This paper shows that the answer is typically no, with the exception of police hiring and spending.  [Supplemental Information]

Inactive by Design: Neighborhood Design and Political Participation

Political Behavior, 2012, 34(1):79-101, co-authored with Thad Williamson

Suburban communities in the U.S. have sometimes been condemned for their lack of civic engagement.

Using Conjoint Experiments to Analyze Elections: The Essential Role of the Average Marginal Component Effect (AMCE)

Co-authored with Kirk Bansak, Jens Hainmueller, and Teppei Yamamoto

This paper provides a general framework for analyzing voter preferences in multi-attribute elections using conjoints. With this framework, we demonstrate that the Average Marginal Component Effect (AMCE) is well-defined in terms of individual preferences and represents a central quantity of interest to empirical scholars of elections: the effect of a change in an attribute on a candidate or party’s expected vote share.

This paper exploits the public release of more than 200,000 internal emails by the Enron Corporation to better understand the types of lobbying that Enron engaged in.  Enron devoted only a small fraction of its attention to campaigns and elections, and was far more active in formally participating in bureaucratic processes than previous work might suggest.  It also uses tools from automated content analysis to focus attention on political emails.  [Award: Best Paper, Political Organizations and Parties Section of APSA, 2010]

Improving Anchoring Vignettes: Designing Surveys to Correct Interpersonal Incomparability

Public Opinion Quarterly, 2010, 74(2):201-222, co-authored with Gary King

Anchoring vignettes are an increasingly common tool to reduce differences in how respondents interpret survey questions.  This paper uses survey experiments to develop insights about how to design surveys with anchoring vignettes. It shows that placing vignettes prior to a self-assessment question can prime respondents, improving the measurement of the underlying concept. It also develops advice for survey questions that ask respondents to compare themselves to others. [Data]

A Method of Nonparametric Automated Content Analysis for the Social Sciences

American Journal of Political Science, 2010, 54(1):229-247, co-authored with Gary King

The explosion of blogs and other digitized text presents opportunities to measure public opinion in new ways.  This paper presents methods of automated content analysis that give approximately unbiased estimates of the proportion of documents falling into pre-specified categories.  It then applies these methods to data on thousands of web logs about the 2008 U.S. Presidential election.

The Constraining Power of International Treaties: Theory and Methods

American Political Science Review, 2005, 99(4):623-631, co-authored with Beth Simmons

Owing to self-selection, estimating treaty effects is challenging, as countries are more likely to sign treaties if they expect to comply with them. This paper argues that treaties can both screen among states and then constrain those states that become signatories. It uses propensity score matching, and finds that signing onto the International Monetary Fund’s Article VIII has a marked impact on signatories’ behavior. [Data]
