Knowledge that Transforms

This paper estimates the causal impacts on child skills and the mechanisms producing these impacts using data from a randomized control experiment. We study a widely emulated early-childhood home visiting program and show the feasibility of replicating it at scale. We go beyond reporting treatment effects as unweighted item scores and assess item difficulties. To interpret treatment effects, we estimate individual-level latent skills and compare treatments and controls. The program substantially improves multiple skills. We decompose the source of treatment effects and find that enhancements in latent skills explain most of the conventional treatment effects for language and cognition.

This study examines the long-term effects of student loans and grants in Chile through a regression discontinuity design. It finds that university loans significantly boost degree completion, especially among women and low-income students, with marginal positive effects on employment and earnings for women. Vocational loans benefit only those ineligible for university loans. Conversely, grants, alongside loans, do not affect education or labor market outcomes. The limited impact of the tuition reductions induced by grants, combined with the substantial gains for low-income students, highlights the presence of credit constraints.

This paper evaluates self-employment assistance (SEA) programs, which are government initiatives extending the unemployment insurance system to support unemployment to self-employment transitions. Using a general equilibrium model of the US labor market, we show that these programs have important labor market mobility effects and increase the self-employment rate. They also significantly impact the composition and performance outcomes of self-employment: while lump-sum subsidies select low-skilled individuals, SEA programs contingent on previously employed earnings select skilled and wealthier individuals. At the aggregate level, the latter programs mainly reallocate individuals from employment to self-employment, leaving the unemployment rate largely unaffected.
