Paying Off Populism: How Regional Policies Affect Voting Behavior

This paper shows that regional policies can decrease populist support. We focus on the “development objective” (Objective-1) of the European Regional Development Fund (ERDF), meant to support lagging-behind regions. For causal inference, we exploit three sources of quasi-exogenous variation in a Regression-Discontinuity-Design (RDD), a Difference-in-Differences framework (DiD), and with matching techniques. Using NUTS3-level panel data on the outcomes of elections to the EU parliament, observed over the period 1999-2019, we consistently find that Objective-1 transfers reduces the vote share of right-fringe parties by about 2.5 pp. Left-fringe party support is not affected. Complementary analyses of individual-level survey data from the Eurobarometer show that the European Regional Policy increases trust in democratic institutions and decreases discontent with the EU.
