Individual and Social Effects of Shelter for People Experiencing Homelessness: Evidence From Los Angeles County's Winter Shelters Program
Abstract
We exploit variation from shocks to shelter availability from Los Angeles County's winter shelters program to study the effects of shelter provision and sheltered (versus unsheltered) homelessness. We leverage records of homeless services to generate daily, site-level counts of shelter beds and occupants from 2014 to 2019. We pair shelter counts with block-level crime data and facility-level data on ER visits to assess the impacts of shelter on crime and health outcomes. Further, using enrollment-level homeless services data, we evaluate the effect of shelter on returns to homeless services, observed exits from homelessness, and observed mortality. While preliminary estimates suggest that street outreach may be just as effective as shelter in reducing an individual's likelihood of still being homeless 6-18 months in the future, our findings indicate that increased investment in shelter provision may be optimal given its ability to mitigate both private and social costs of homelessness.The Labor Market Returns to Customized Job Training
Abstract
Economic theory dating back to Becker (1962) predicts that employers and workers should share the cost of job training in specific, non-transferable skills, leaving workers or the government to fund general skills training. Customized job training (CJT) programs, which exist in most U.S. states, defy this logic by using public subsidies to teach workers a range of skills, including those that are firm-specific. Are governments mistakenly subsidizing training that firms would pay for on their own, or does CJT generate benefits that justify public investment? I answer these questions using unique hand-collected data from Tennessee on firms' grant applications and trainees' enrollment linked with rich administrative data on education, earnings, and public assistance. I exploit the fact that there is quasi-random rationing among equally comparable firms and equally eligible prospective trainees. The estimates show that enrolling in a CJT program, typically lasting about four months, increases earnings by 3% per quarter over five years, comparable to the return from one additional year of work experience. To explain these findings, I classify the skills taught in each program by mapping program descriptions in firms' grant applications to O*NET detailed work activities. Despite the fact that CJT programs primarily produce transferable skills across industries and occupations, benefits to the government through higher individual income tax revenues more than offset training costs, yielding an exceptionally high marginal value of public funds relative to other job training programs.How Retrainable Are AI-Exposed Workers?
Abstract
We document the extent to which AI-exposed workers can successfully retrain for AI-intensive work. We assemble a new job training dataset spanning over 2.9 million unique job training participation spells from all U.S. Workforce Investment Act (WIA) programs between 2012 – 2023. Linking occupational measures of AI exposure with earnings records observed both before and after training, we compare earnings and occupational transitions of job trainees to observationally similar AI-exposed workers who only received job search assistance services through the Wagner-Peyser program. We then construct an AI retrainability index (AIR) at the occupation level that weights transitions into more AI-intensive occupations by individual earnings returns from training. This allows us to disentangle whether AI retrainability is driven by AI skill transitions versus general returns to training.Discussant(s)
