This paper documents ‘real-time’ cultural and political spillovers from countries of origin to 1st and 2nd generation immigrants. Leveraging the across- and within-country variation in attitudes produced by the 2015 European Refugee Crisis, I show that (i) opposition towards non-European immigrants, and (ii) voting for right-wing populist parties spill over from European countries involved in the Crisis to immigrants from these countries living elsewhere. These spillover effects are comparable in size to pre-existing differences between left- and right-leaning respondents. Using data from Google Trends and Facebook, as well as additional surveys, I show that (i) network homophily, (ii) immigrants’ integration into host communities, and (iii) social media ties are likely mechanisms behind these spillover effects. Currently in process is data collection from the online survey experiment, which will allow disentangling competing mechanisms.
