Financial aid from the Susan Thompson Buffett Foundation (STBF) provides exceptionally generous support to a college population similar to that served by a host of state aid programs. In conjunction with STBF, we randomly assigned aid awards to thousands of Nebraska high school graduates from low-income, minority, and first-generation college households. Randomly- assigned STBF awards boost bachelor's (BA) degree completion for students targeting four-year schools by about 8 points.

We carry out a comparative analysis of inequality of opportunity (IOp) for long-run income in Denmark and the United States. We adopt a luck-egalitarian understanding of IOp, use high-quality administrative data, and rely on highly improved methods. These include novel identification assumptions that allow us to produce set estimates of IOp in the United States relative to Denmark rather than just lower-bound estimates of IOp in the two countries. There are five main results.

We use 10 years of California administrative data with a regression kink design to estimate the causal impacts of benefits in the first state‐level paid family leave program for women with earnings near the maximum benefit threshold. We find no evidence that a higher weekly benefit amount (WBA) increases leave duration or leads to adverse future labor market outcomes for this group.

We conduct a comparative welfare analysis of 133 historical policy changes over the past half-century in the United States, focusing on policies in social insurance, education and job training, taxes and cash transfers, and in-kind transfers. For each policy, we use existing causal estimates to calculate the benefit that each policy provides its recipients (measured as their willingness to pay) and the policy’s net cost, inclusive of long-term effects on the government’s budget.

Without the opioid epidemic, American life expectancy would not have declined prior to 2020. In turn, the epidemic was sparked by the development and marketing of a new generation of prescription opioids and provider behavior is still helping to drive it. There is little relationship between the opioid crisis and contemporaneous measures of labor market opportunity. Cohorts and areas that experienced poor labor market conditions do show lagged increases in opioid mortality, but the effect is modest relative to the scale of the epidemic.
