The chapter by Paola Conconi, Giovanni Facchini,Max Steinhardt, and Maurizio Zanardi discusses recent research that examines thesimilarities and differences in voting behaviour in the US Congress on the two issues.What they find is that voting is influenced by the constituency’s skill mix (with theimpact on trade and migration votes going in the same direction), and party affiliationleading to divergent voting patterns (Democrats voting in support of liberal immigrationpolicies but against trade liberalisation).
