As debate over immigration policy continues in the nation’s capital and across the country, research by 鶹Porn professor and two colleagues continues to add to the dialogue.
In 2013, began research showing that an — a program for U.S. companies to bring in skilled immigrants — did not harm U.S. workers or the U.S. economy.
In fact, the research found that “inflows of foreign H-1B workers may explain between 30% and 50% of the aggregate productivity growth… that took place in the US between 1990 and 2010.”
Sparber and his research associates — Giovanni Peri and Kevin Shih, both of the University of California, Davis — continue to study the numbers, and and their impact on the STEM professions: science, technology, engineering and mathematics.
According to a report in the , the research team found that as immigrants in the STEM professions flocked to a city, the more wages grew for the native-born, college-educated population. Their findings were released this month by the .
“A one percentage point increase in the foreign STEM share of a city’s total employment increased wages of native college-educated labor by about 7-8 percentage points and the wages of non-college educated natives by 3-4 percentage points,” according to the Journal article.
Importantly, their results identify a causal effect of immigration on wages that is distinct from the fact that productive cities will attract more immigrants.
