Cushion or catalyst? How welfare state generosity moderates the impact of economic vulnerability on populist radical right support

The rise of populist radical right parties represents one of the most dramatic shifts in European party systems of the past decades. Although it has been established that the populist radical right's core appeal centers around issues of immigration and multiculturalism rather than economic matters, there has been a debate in the literature about the role of socioeconomic factors as a driver of PRRP success. We focus on two strands of argument relating to the welfare state and its impact on PRRP support. On the one hand, generous social policy regimes may mitigate the adverse economic effects of globalization and thus make workers less vulnerable to the appeal of populist radical right parties (the inoculation hypothesis). On the other hand, generous welfare regimes may make voters more concerned about increased numbers of low-skilled immigrants entering a country and potentially claiming benefits paid for largely by the taxes and contributions of the native population (the welfare chauvinism hypothesis). Our results suggest several channels through which the welfare state affects votes for the PRRP. Firstly, social protection seems to moderate economic vulnerability: in countries with higher relative redistribution and/or poverty prevention, the economically vulnerable are less likely to vote for the PRRP. Secondly, the direct effect of social welfare measures on the populist vote is positive when considering individual voters' positions. Thirdly, a stronger welfare state contributes to increasing the salience of the immigration platform for voting decisions. As a result, voters in high-redistribution countries are more likely to vote for the PRRP if they have a more moderate view on migration.
