Does corruption influence trust in national institutions in the same way as trust in international institutions? Did this influence change over the economic crisis 2008? Using data from the European Social Survey, we examined the association between corruption and trust in national and European parliaments before and after the start of the Great Recession 2008. We found that over the Crisis, the effect of corruption on trust in national parliament became more negative than it was before 2008. We also discovered a positive association between corruption and trust in the EU before the Crisis. That is, states with a higher level of national corruption seem to have more trust in international institutions, such as the EU. However, this relationship disappears after 2008. Our findings contribute to the debates on the impact of corruption on trust in national and international institutions, and on the consequences of the Great Recession.
