Funds from this grant support the research of Prasanna Tambe of New York University, who proposes to exploit new sources of administrative data to shed light on the labor market economics of the IT workforce. Using millions of administrative records collected by popular job-related social media sites LinkedIn and CareerBuilder, Tambe will examine variations in the labor market behaviors of IT workers and firms, examining how the acquisition of IT skills by employees in a firm affect the firm's productivity, how firms value the acquisition of new IT skills, and how employee migration between firms affects the rate of adoption of new technology.
