Using a novel database of 82.5 million online job postings, we show that employer skill requirements fell as the labor market improved from 2010 to 2014. We find that a 1 percentage point reduction in the local unemployment rate is associated with a roughly 0.27 percentage point reduction in the fraction of jobs requiring at least a bachelor's degree and a roughly 0.23 percentage point reduction in the fraction requiring five or more years of experience. This pattern is established using multiple measures of labor availability, is bolstered by similar trends along heretofore unmeasured dimensions of skill, and even occurs within firm-job title pairs. We further confirm the causal effect of labor market tightening on skill requirements using a natural experiment based on the fracking boom in the United States as an exogenous shock to the local labor supply in tradable, non-fracking industries. These industries are not plausibly affected by local demand shocks or natural gas extraction technology, but still show fewer skill requirements in response to tighter labor markets. Our results imply this labor market-induced downskilling reversed much of the cyclical increase in education and experience requirements that occurred during the Great Recession.

In the wake of the Great Recession, policymakers and academics have expressed concerns about rising employer skill requirements. Using a large database of online job postings for middle-skill occupations, we demonstrate that employers opportunistically raise education and experience requirements, within occupations, in response to increases in the supply of relevant job seekers. This relationship is robust to numerous tests for potentially confounding factors, is present even within firm-job title pairs, and is consistent with the predictions of a standard employer search model. We further identify this effect by exploiting the natural experiment arising from troop-withdrawals in Iraq and Afghanistan as an exogenous shock to local, occupation-specific labor supply. Our results imply that increases in the number of people looking for work can account for roughly 30 percent of the total increase in employer skill requirements observed between 2007 and 2010.

Cities across the U.S. have turned to summer youth employment programs (SYEPs) to improve the behavioral, economic, and academic outcomes of inner‐city youth. This paper evaluates the impact of the Boston Summer Youth Employment Program using both experimental and non‐experimental variation. Similar to previous studies of summer jobs programs in other cities, I make use of an embedded randomized controlled trial and find that the program reduces violent crime by 35 percent, as measured by the number of arraignments from administrative records during the 17 months after participation. In contrast to prior work, I also find a similar reduction in arraignments for property crimes (−29 percent). This study also provides exploratory evidence on the mechanisms driving these reductions in crime using self‐reported responses of participants from a pre‐/post‐program survey. The results provide suggestive evidence that the beneficial impacts on violent and property crime are largely driven by improved conflict resolution skills versus other factors that would increase the opportunity cost of crime. These findings give researchers some insights into the behavioral changes that occur during the program while also providing a look inside the “black box” as to how SYEPs affect youth outcomes in the long run.

U.S. policymakers are concerned that negative home equity arising from the severe housing market decline may be constraining geographic mobility and consequently serving as a factor in the nation's persistently high unemployment rate. Indeed, the widespread drop in house prices since 2007 has increased the share of homeowners who are underwater on their mortgages. At the same time, migration across states and among homeowners has fallen sharply. Using a logistic regression framework to analyze data from the Internal Revenue Service on state-to-state migration between 2006 and 2009, the authors discover evidence that "house lock" decreases mobility but find it has a negligible impact on the national unemployment rate. A one-standard deviation increase in the share of underwater nonprime households in the origin state reduces the outflow of migrants from the origin to the destination state by 2.9 percent. When aggregated across the United States, this decrease in mobility reduces the national state-to-state migration rate by 0.05 percentage points, resulting in roughly 110,000 to 150,000 fewer individuals migrating across state lines in any given year. Assuming that all of these discouraged migrants were job-seekers who were previously unemployed before relocating and then found a job in their new state would reduce the nation's unemployment rate by at most one-tenth of a percentage point in a given year. The cumulative effect over this period would yield an unemployment rate of 9.0 percent versus 9.3 percent in 2009. Recognizing that not all state-to-state migrants are job-seekers, not all jobseekers were previously unemployed, and not all previously unemployed job-seekers will successfully find work in their new location yields an unemployment rate that is virtually unchanged from the actual one that prevailed from 2006 to 2009.

This paper reports the results of the first systematic attempt at quantitatively measuring the seminar culture within economics and testing whether it is gender neutral. We collected data on every interaction between presenters and their audience in hundreds of research seminars and job market talks across most leading economics departments, as well as during summer conferences. We find that women presenters are treated differently than their male counterparts. Women are asked more questions during a seminar and the questions asked of women presenters are more likely to be patronizing or hostile. These effects are not due to women presenting in different fields, different seminar series, or different topics, as our analysis controls for the institution, seminar series, and JEL codes associated with each presentation. Moreover, it appears that there are important differences by field and that these differences are not uniformly mitigated by more rigid seminar formats. Our findings add to an emerging literature documenting ways in which women economists are treated differently than men, and suggest yet another potential explanation for their under-representation at senior levels within the economics profession.
