A study involving the UAB has analyzed the effect of foreign trade and immigration on the success of both right- and left-wing populist parties. The analysis reveals how the importation of products that require low-skilled labor plays a key role in the rise of both types of populism, while immigration with low levels of education increases right-wing populism. Conversely, highly educated immigrants and imports requiring a high level of skilled labor reduce support for populism. The study proposes the implementation of selective policies as an alternative solution to protectionism and immigration barriers.
