We estimate the causal effect of having full health insurance on health care expenditures. We take advantage of a unique quasi-experimental setup in which deductibles and co-payments were zero in a managed care plan, and non-zero in regular insurance, until a policy change forced all individuals...

In the debate over immigration reform, it is frequently asserted that immigrants take jobs that U.S. natives do not want. Using data from the 2000 Census merged with O*NET data on occupation characteristics, I show that the jobs held by immigrants are more physically arduous than the jobs held...

Much of human knowledge is produced in the world's university departments. There is little scientific evidence, however, about how those hundreds of thousands of departments are best organized and led. This study hand-collects longitudinal data on departmental chairpersons in 58 US universities...

We use twin data matched to register-based individual information on earnings and employment to examine the effect of height on life-time labor market outcomes. The use of twin data allows us to remove otherwise unobserved ability and other differences. The twin pair difference estimates from...

We study the causal impact of the minimum wage on employment and welfare in Thailand using a difference-in-difference approach that relies on exogenous policy variation in minimum wages across provinces. We find that minimum-wage increases have small disemployment effects on female, elderly, and...

Does availability of common law marriage (CLM henceforth) in the U.S help explain variation in the labor force participation, hours of work and hours of household production of men and women over time and across states? As CLM offers more legal protection to household producers at the margin...

Is there a reward for basic skills in the German labor market? To answer this question, we examine the relationship between literacy, numeracy and monthly gross earnings of full-time employed workers. We use data from the ALWA survey, augmented by test scores on basic cognitive skills as well as...

This paper examines the welfare loss of import restrictions on bananas in Australia and whether the import restrictions have turned into a particular form of export promotion. We set up a model in which there is free domestic entry, with banana producers accepting losses in normal years, off-set...

Derek Neal (JPE 2004) used the NLSY79 to show that the observed median log wage gap between young white and young black women in 1990 underestimated the true, selection-corrected gap, i.e., the gap we would have expected to see had all of these women been employed in 1990. In this paper, we use...

This paper investigates the short term effects of a large scale intervention, funded by the European Social Fund, that provides additional instruction time to students in low achieving lower secondary schools of Southern Italy. We control for sorting across classes using the fact that freshman...
