Alberto Alesina on Immigration and Redistribution

Episode Summary

Executive Summary: Russ Roberts and Alberto Alesina discuss Alesina’s paper on immigration and redistribution across six countries. The key finding is that natives systematically overestimate immigrant shares and often misperceive immigrants’ origins and welfare use; merely priming respondents with immigration questions makes them less supportive of redistribution. The conversation links these misconceptions to broader debates over populism, identity, and policy.

Main Topics: Research goal: immigration, diversity, and redistribution (Priority: 5/5): Alesina explains the paper as part of a broader project on why people support or oppose redistribution, especially in increasingly diverse societies. Sampling design and legal immigrants (Priority: 5/5): The study focuses on native-born respondents in the US, UK, Sweden, Italy, France, and Germany, and deliberately defines immigrants as legal foreign-born residents to avoid conflating immigration with illegality. Misperceptions about immigrant numbers and origins (Priority: 5/5): Respondents across countries greatly overestimate the share of immigrants and also misjudge where immigrants come from, often exaggerating Muslim/poor/problematic origins and undercounting Christian or culturally similar immigrants. Ideology and stereotypes (Priority: 4/5): Political ideology matters for judgments about immigrant traits like laziness, poverty, and welfare dependence, but not much for estimating immigrant population size; right-leaning respondents show stronger negative stereotypes. Immigration and redistribution attitudes (Priority: 5/5): The paper finds that hearing immigration questions first reduces support for redistribution, suggesting that immigration salience shifts people away from egalitarian policy preferences. Cultural identity, media, and populism (Priority: 4/5): Roberts and Alesina connect the findings to media-driven exaggeration, cultural anxiety, and the rise of anti-immigration politics in the US and Europe. US vs Europe and assimilation (Priority: 4/5): They contrast America’s melting-pot tradition with Europe’s weaker history of immigration and integration, arguing that European societies are less prepared to absorb large immigrant inflows.

Key Arguments: Native respondents in all six countries substantially overestimate the share of immigrants in their population, and the error is broadly similar across education, income, gender, and whether they know immigrants. The main respondent characteristic associated with larger overestimation is working in a sector with more immigrants, suggesting self-interest or workplace exposure shapes perceptions. People across countries systematically overestimate immigrants from salient or culturally distant groups (e.g., Muslims, North Africans, Latin Americans) and underestimate more culturally similar groups. Respondents often believe immigrants receive more welfare benefits than natives, even when given identical income and family profiles except for a name signaling immigrant status. Simply activating thoughts about immigration before asking redistribution questions makes respondents less supportive of redistribution, by a meaningful amount relative to ideology gaps. The paper does not claim immigrants are objectively bad for redistribution; instead, it shows that misperceptions about immigrants can influence policy preferences and may fuel anti-immigration attitudes. Alesina argues that real data should replace stereotypes in public debate, because misinformation shapes both redistribution politics and immigration policy. Roberts emphasizes that media ecosystems may intensify fear and xenophobia by repeatedly highlighting vivid, exceptional, or crime-related immigration stories.

Data Points: Countries studied: 6 - United States, United Kingdom, Sweden, Italy, France, Germany Total respondents: About 23,000 - Survey sample across the six countries US legal immigrants share: About 10% - Alesina cites the US as having roughly one-tenth of the population foreign-born/legal immigrant US illegal immigrants share: About 3.5% - Mentioned as a comparison point in the US Sweden immigrant share: About 18% - Used to compare perceptions with reality Average perceived immigrant share in the US: About 30% - Respondents overestimated the immigrant population Average perceived immigrant share in Sweden: About 27% - Closer to the actual 18% than other countries Typical overestimate of immigrant share: Around 15 percentage points - Alesina says colleagues often guessed around 15% rather than 10% in casual conversation Respondents seeing immigration first and thinking inequality is a problem: About 5% more likely - Immigration priming reduced support for redistribution-related views Effect size relative to ideology gap: About 13% of the gap between left- and right-wing respondents - Summary measure of the priming effect on redistribution attitudes US respondents who say the poor are poor due to lack of effort: About 70% - Referenced as background on attitudes toward the poor and redistribution European respondents who say the poor are poor due to lack of effort: About 30% - Compared with the US on attitudes toward poverty and effort Respondents believing immigrant named person gets more than native named person: Up to 50% in France and Italy - In the identical-profile vignette with different names Respondents believing immigrant named person gets more than twice as much: About 20% in France; somewhat lower elsewhere - Extreme misperception in the same-name experiment

Pivotal Quotes: "Making people think about immigration makes them much less favorable to redistribution." — Alberto Alessina: Summarizing the paper’s key experimental finding on question order and redistribution attitudes "The conversation should be happening with real data and not with perceived data." — Alberto Alessina: On policy debate over immigration and redistribution "I couldn’t agree more." — Russ Roberts: Agreeing with the claim that media and stereotypes can amplify fears of immigration

Implications: The episode suggests immigration debates are driven as much by perception as reality. Better data, clearer definitions, and less sensational media framing could improve public understanding and reduce distortion in redistribution and immigration policy debates.
