We compare winning and losing firms in lotteries for H-1B visas, matching administrative data on these lotteries to administrative tax data on U.S. firms and to approved U.S. patents. Winning one additional H-1B visa crowds out about 1.5 other workers at the firm. Additional H-1Bs have...

We develop a procedure for adjudicating between models of firm wage-setting conduct. Using data on workers' choice sets and decisions over real jobs from a U.S. job search platform, we first estimate workers' rankings over firms' non-wage amenities. We document three key findings: 1) On average,...

We study how firm-specific complementary assets and intellectual property rights affect the management of knowledge workers. The main results show when a firm will wish to sue workers that leave with innovative ideas, and the effects of complementary assets on wages and on worker initiative. We...

In this paper we investigate how active labour market policy programmes affect firms' hiring strategies and, eventually, firms' performance. We focus on counseling and monitoring which may reduce search costs for employers, but which may have ambiguous effect on the employer-employee matching...

We study how the presence of a college affects the local economy using administrative data. Our analysis exploits the opening of new institutions of tertiary education across Germany in the 1980s and 1990s. The new college substantially increased the student population and share of high-skilled...

Recent immigration policies have created massive uncertainty for international students to obtain F-1 visas. Yet, before the COVID-19 pandemic, student visa applicants already faced an approximately 27 percent refusal rate that varies by time and region. Using data on the universe of SAT takers...

We study both endogenous and exogenous peer effects in worker productivity using an explicit network approach. We apply this method to data from an in-house call center of a multinational mobile network operator that include detailed information on individual performance. We find that a 10%...

We examine the changes in the relative rewards to cognitive and non-cognitive skill during the time period 1992–2013. Using unique administrative data for Sweden, we document a secular increase in the returns to non-cognitive skill, which is particularly pronounced in the private sector and at...

We conduct a study under 2,400 third grade students at three large secondary comprehensive schools to evaluate a gifted and talented (GT) program with selective program admission based on past achievement. We construct three complementary estimates of the program's impact on student achievement....
