註釋We study the effect of a firm winning an additional H-1B visa on the firm's outcomes, by comparing winning and losing firms in the Fiscal Year 2006 and 2007 H-1B visa lotteries. We match administrative data on the participants in these lotteries to the universe of approved U.S. patents, and to IRS data on the universe of U.S. firms. Winning additional H-1B visas has an insignificant effect on patenting within eight years, with confidence intervals that rule out moderate-sized or larger effects. H-1Bs substantially crowd out employment of other workers. We find some evidence that additional H-1Bs lead to lower average employee wages while raising firm profits.
