COVID-19 threat and negative attitudes toward outgroup and ingroup others: A multilevel analysis with coarsened exact matching

Using two waves of nationally representative data, the present study shows the extent to which the COVID-19 pandemic has exacerbated anti-outgroup and anti-ingroup attitudes among South Korean adults. To that end, in a quasi-experimental setting, it exploits the survey interview timing as a source of exogenous variation to investigate the causal influence of the COVID-19 pandemic. Data imbalance is initially corrected using the coarsened exact matching procedure. Then, a series of multilevel models, with data on 10,454 subjects nested in 34 wave–region units, are estimated with additional covariate adjustment to improve estimate precision. Results show that, first, those who are more relatively deprived became less inclined to support the granting of citizenship status to foreigners since the coronavirus outbreak. Second, the same trend was found among individuals who are more dissatisfied with the country’s overall economic condition. Third, in the wake of the global health crisis, Korean natives became less willing to pay additional taxes to support conational others who are economically underprivileged.
