One of the greatest achievements of the EU is the freedom of movement between member states offering citizens equal rights in EU member states. EU enlargement and the COVID-19 pandemic allow for a critical test of whether EU citizens are indeed treated equally in practice. We test preferential treatment of EU citizens in two hypothetical choice experiments in Germany at two different time points: in the period before and during the COVID-19 pandemic lockdown. Theories of responses to threat suggest that the COVID-19 crisis should increase discrimination against mobile EU citizens. While our findings reveal sizeable discrimination based on nationality and language proficiency of mobile EU citizens, the findings also suggest that, contrary to expectations, discrimination did not increase in the initial COVID-19 crisis period.
