Section 1502 of the Dodd–Frank Act requires SEC‐registered issuers to conduct supply chain due diligence and submit conflict minerals disclosures (CMDs) that indicate whether their products contain tantalum, tin, tungsten, or gold (3TG) sourced from the Democratic Republic of the Congo (DRC) or its neighboring countries (“covered countries”). Consistent with the reputational cost hypothesis, we find that heightened public attention to CMDs increases responsible sourcing. After Section 1502 takes effect, we find higher demand for 3TG products processed in certified smelters, decreased conflicts in covered countries’ mining regions relative to other regions, and reduced sensitivity of conflict risk to conflict minerals’ price spikes. Finally, we find that conflicts decrease in Eastern DRC territories with prevalent 3T (tantalum, tin, and tungsten) mines but increase in territories with prevalent gold mines. Overall, our findings highlight the real effects of enhanced supply chain transparency regulation.

We investigate how the presence of a college affects local educational attainment. As counterfactuals for current college locations, we use historical “runner-up” locations that were strongly considered to become college sites but were ultimately not chosen. We find that winning counties today have college degree attainment rates 56% higher than runner-up counties and more private-sector employment in human-capital-intensive industries. These effects are not driven primarily by recent in-migration of educated adults, and alternative public investments did not have similar effects on local educational attainment. The results indicate that colleges played an important role in shaping long-run local outcomes.

We examine the value of due diligence recommendations on Reddit’s Wallstreetbets (WSB) platform. Before the Gamestop (GME) short squeeze, recommendations are significant predictors of returns and cash-flow news. This predictability is eliminated post-GME. Post-GME, the fraction of reports emphasizing price-pressure or attention-grabbing stocks dramatically increases, and the decline in informativeness is concentrated in these reports. Similarly, retail trade informativeness is particularly strong following DD reports in the pre-GME period, but not post-GME. Our findings are consistent with the view that the Gamestop event altered the culture of WSB, leading to a deterioration in investment quality that adversely affected smaller investors.

We use a novel identification strategy to investigate whether regional universities make their local economies more resilient. Our strategy is based on state governments using similar site-selection criteria to assign normal schools (to train teachers) and insane asylums between 1830 and 1930. Normal schools became larger regional universities while asylum properties mostly continue as small state-owned psychiatric health facilities. We find that a regional university roughly offsets the negative effects of manufacturing exposure. We show the resilience of regional public university spending is an important mechanism, and we show correlations consistent with bachelor’s degree share also playing a mediating role.
