This paper formulates and estimates multistage production functions for children's cognitive and noncognitive skills. Skills are determined by parental environments and investments at different stages of childhood. We estimate the elasticity of substitution between investments in one period and...

We estimate the causal impact of school and classroom gender composition on achievement. We take advantage of the random assignment of Korean middle school students to single-sex schools, co-educational (coed) schools with single-sex classes, and coed schools with mixed-gender classes. Male...

This paper argues that a broad class of search models cannot generate the observed business-cycle-frequency fluctuations in unemployment and job vacancies in response to shocks of a plausible magnitude. In the U.S., the vacancy-unemployment ratio is 20 times as volatile as average labor...

We provide a test for statistical discrimination or rational stereotyping in in environments in which agents learn over time. Our application is to the labor market. If profit maximizing firms have limited information about the general productivity of new workers, they may choose to use easily...

A longstanding puzzle of empirical economics is that average labor productivity declines during recessions and increases during booms. This paper provides a framework to assess the empirical importance of competing hypotheses for explaining the observed procyclicality. For each competing...

Firms and other organizations establish the criteria under which employees will be judged and the performance measures made available to supervisors, the board of directors and other stakeholders, and these structures almost certainly influence behavior and organization outcomes. Any divergence...

Employment and hours appear far more cyclical than dictated by the behavior of productivity and consumption. This puzzle has been called "the labor wedge" -- a cyclical intratemporal wedge between the marginal product of labor and the marginal rate of substitution of consumption for leisure. The...

We examine monthly variation in weekly work hours using data for 2003-10 from the Current Population Survey (CPS) on hours/worker, from the Current Employment Survey (CES) on hours/job, and from the American Time Use Survey (ATUS) on both. The ATUS data minimize recall difficulties and constrain...

Using data from a group incentive program that provides cash bonuses to teachers whose students perform well on standardized tests, we estimate the impact of incentive strength on student achievement. These awards are based on the performances of students within a grade, school and subject,...
