The Effect of Trade on Workers and Voters

Abstract We investigate economic causes of the rising support of populist parties in industrialised countries. Looking at Germany, we find that exposure to imports from low-wage countries increases the support for nationalist parties between 1987–2009, while increasing exports have the opposite effect. The net effect translates into increasing support of the right-populist Alternative for Germany party after its emergence in 2013. Individual data from the German Socio-Economic Panel reveal that low-skilled manufacturing workers’ political preferences are most responsive to trade exposure. Using a novel approach to causal mediation analysis, we identify trade-induced labour market adjustments as an economic mechanism causing the voting response to international trade.
