The use of H-1B workers by U.S. companies is decreasing wages for computer programmers, system analysts, and software engineers by as much as 6 percent, according to a study released this week by researchers at New York University's Stern School of Business and the Wharton School of the University of Pennsylvania.
These researchers said they found evidence that the wages are falling by accessing tens of thousands of resumes provided by a "leading online job search site" they wouldn't identify, to gain demographic and wage data of individual companies. That data was combined publicly available data sources, including H-1B hiring figures compiled by the U.S. government, and studies showing average wages for specific IT jobs.
The report's authors said that they are not using the study to take a position on H-1B visa use and do not discount other research that has found that H-1B visa holders are helping U.S. competitiveness.
"In this paper, we simply sought to dispel the myth that globalization generates no losers," wrote Prasanna Tambe, an assistant professor of information, operations and management sciences at the Stern School and Lorin Hitt, a professor of operations and information management at Wharton. The authors said that it's important that policy makers understand the wage impact of the H-1B visa program..
The study is unique, the authors said, because of its study of all the resumes. That combined with other public sources of data, gave them a sample number of IT workers in each firm, which they coupled with the number of H-1B workers these firms reported hiring. In total, the study was based on information the researchers compiled on 156,000 IT workers employed at nearly 7,500 publicly held U.S. firms.
"The relationship I'm investigating here is how compensation looked for domestic workers, depending on whether or not their employers are using offshore and H-1B employment," said Tambe.
What they found is that H-1B admissions at current levels are associated with a 5 to 6 percent drop in wages for computer programmers, systems analysts and software engineer categories. Offshore outsourcing also decreases wages for a broader category, including IT managers, by 2 to 3 percent, the study found.
The IT workers most likely to be affected by the downward pressure on wages are recent college graduates and people changing jobs, the researchers said.
A draft of the 32-page paper was posted this week on the Social Science Research Network. A study released last year by Tambe and Hitt found that as many as 8 percent of IT workers have been displaced by offshore outsourcing, either through job loss or job transfer.
The debate over the impact of H-1B workers on existing IT workers is contentious, particularly on how the foreign workers impact wages.
