We propose a simple theory of under- and over-employment. Individuals of high type can perform both skilled and unskilled jobs, but only a fraction of low-type workers can perform skilled jobs. People have different non-pecuniary values over these jobs, akin to a Roy model. We calibrate two...

Using longitudinal data for Canada, we analyze the incidence and wage returns to employer supported course enrollment for men and women. Availability of confidential data, along with a relatively rich set of observable covariates, lead us to the estimation of difference-in-differences matching...

In 2003, Germany moved from a system in which participants in training programs for the unemployed are assigned by caseworkers to an allocation system using vouchers. Based on the rich administrative data for all vouchers and on actual program participation, we provide inverse probability...

This study fills a gap in the literature on the outcome mechanisms in which successful training programs improve employment and earnings, such as raises on the job or longer job duration. The city of New Orleans implemented a job training program as an RCT for low-income workers. Individuals in...

This study analyzes the effects of a missing high school graduation cohort on firms' training provision and trainees' wages. An exogenous school reform varying at the state and year level caused the missing cohort to occur. Using administrative social security data on all trainees and training...

This paper presents new evidence that increases in college enrollment lead to a decline in the average quality of college graduates between 1960 and 2000, resulting in a decrease of 6 percentage points in the college premium. We show that although a standard demand and supply framework can...

This paper uses data from the 2010 American Community Survey (ACS) to study the returns to language skills of child and adult migrants in the US labor market. We employ an instrumental variable strategy, which exploits differences in language acquisition profiles between immigrants from English-...

This paper documents variation in working conditions among workers in the United States, presents new estimates of how workers value these conditions, and assesses the impact of working conditions on estimates of the wage structure and inequality. We use evidence from a series of stated...

Neoclassical trade theory suggests that factor price convergence should follow increased commercial integration. Rising commercial integration and foreign direct investment followed the 1994 North American Free Trade Agreement between the United States and Mexico. This paper evaluates the degree...

Previous studies show that immigrants married to natives earn higher wages than immigrants married to other immigrants. Using data from the 1980-2000 U.S. censuses and the 2005-2010 American Community Surveys, we show that these wage premiums have increased over time. Our evidence suggests that...
