The closing of American borders to mass migration from Europe in the 1920s, one of the biggest immigration policy changes in the country’s history, didn’t raise wages for U.S.-born workers in the areas most affected by the shift, according to a transatlantic team of researchers who say the history offers important lessons for today.

Quotas effectively limiting annual immigration by more than 75% targeted Europe yet exempted Mexico and Canada, encouraging labor flows from those countries to American cities and new capital investment in rural areas, the researchers said in a working paper distributed by the National Bureau of Economic Research.
