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.
