Migrant exposure and anti-migrant sentiment

The subtitle of the paper is The Case of the Venezuelan Exodus, and the authors are Jeremy Lebow, Jonathan Moreno-Medina, Salma Mousa, and Horacio Coral.  Here is part of the abstract:

We study the mass exodus of Venezuelans across Latin America, which coincided with an unprecedented worsening in migrant sentiment in the countries that received the most Venezuelans. However, we find no evidence that this decrease occurred in the regions within-country that received the most migrants. We do this using multiple migrant sentiment outcomes including survey measures and social media posts, multiple levels of geographic variation across seven Latin American countries, and an instrumental variable strategy. We find little evidence for heterogeneity along a range of characteristics related to labor market competition, public good scarcity, or crime. The results are consistent with anti-migrant sentiment being a national-level phenomenon, divorced from local experiences with migrants.

Keep in mind that domestic natives typically have significant (national-level) misinformed objections to the migrants, such as thinking they are far more numerous than in fact they are.  But they don’t dislike the actual presence of the immigrants, quite the contrary.
