	abstract = {This paper asks whether history can inform modern debate about immigration{\textquoteright}s impact
on high wage economies. It examines the relationship between migration{\textquoteright}s labor market
impact and capital flows before 1914, the first global era. It then assesses the effects of
immigration on wages and employment with and without international capital mobility
today, in the second global era. It then explores the links between these economic
relationships, welfare burdens, and immigration policy. It concludes with an explanation
for the apparent difference in immigration{\textquoteright}s impact in the two global eras, and thus on
policy.},
