U3, the official unemployment rate, is an inadequate gauge of labor-market slack and the extent to which it misinforms varies substantially over the business cycle. The U6 unemployment rate is usually about 4 percentage points above U3. However, during the Great Recession it exceeded U3 by 7...

The official U.S. unemployment rate is an inadequate measure of actual labor market conditions. This poses a major challenge for researchers and confuses both the public and policy makers. A new definition of unemployment is proposed. It considers those part-time workers who would like to work...

A general framework is described specifying how boundedly rational decision makers generate their choices. Starting from a Master Module which keeps an inventory of previously successful and unsuccessful routines several submodules can be called forth which either allow one to adjust behavior...

Understanding how people behave in strategic settings–where they make decisions based on their expectations about the behavior of others–is a longstanding problem in the behavioral sciences. We conduct the largest study to date of strategic decision-making in the context of initial play in...

Using a source of 19th century US state prison records, this study addresses European-American stature variation. The most commonly cited sources for stature variation are diets, disease, and work effort. However, vitamin D is also vital in human statures and health. This paper demonstrates that...

Though online technology has generated excitement about its potential to increase access to education, most research has focused on comparing student performance across online and in-person formats. We provide the first evidence that online education affects the number of people pursuing formal...

Though a lot of work has been done on the distribution of job tenures, we are still uncertain about its main determinants. In this paper, we stress random shocks to match productivity after the start of an employment relation. The specificity of investment makes hiring and separation decisions...

We build an analytically and computationally tractable stochastic equilibrium model of unemployment in heterogeneous labor markets. Facing search frictions within markets and reallocation frictions between markets, workers endogenously separate from employment and endogenously reallocate between...

Improving public sector workforce quality is challenging in sectors such as education where worker productivity is difficult to assess and manager incentives are muted by political and bureaucratic constraints. In this paper, we study how providing information to principals about teacher...

Employer-provided health insurance may restrict job mobility, resulting in “job lock.” Previous research on job lock finds mixed results using several methodologies. We take a new approach to examine job-lock by exploiting the discontinuity created at age 65 through the qualification for...
