It is a common conception these days that exposure to international trade and its adverse effects is a major factor in the rise of protectionist parties or candidates in the most advanced economies (Brexit, D.Trump, Front National, ...). The underlying assumption is probably that workers who have lost their job (or fear losing it) due to international competition are more likely to endorse a candidate with a protectionist agenda.
I would like to know if there has been any attempt at identifying the causal effect of exposure to globalization on voting. If someone knows an article whose authors have found some exogenous variation in the data to address this question I would be very interested. Thank you.
