Knowledge that Transforms

Mergers are associated with large and persistent earnings declines for incumbent employees in target firms. Linking employer‐employee administrative data with information on merger activity in Brazil, I find the negative effects concentrate on employees who exit target firms and reflect displacement in the short run and wage declines in the long run. Low‐skilled, managerial, and older employees fare worse. Overall, I conclude that mergers are followed by substantial reallocation costs reflecting losses of firm‐specific wage premiums, matching inefficiencies, and industry‐specific human capital depreciation, with employees transitioning to lower paying firms considered to be of lower productivity and employment value.

We present results from a field experiment that introduced digital payroll accounts to unbanked factory workers to examine how inexperienced consumers learn to use a new financial technology. We find that exposure to payroll accounts leads to increased account use, accelerated learning, and avoidance of common consumer protection risks. Those receiving electronic wage payments gradually build trust in the technology, learn to use accounts without assistance, and avoid illicit fees. Using experimental variation in assignment to bank versus mobile money accounts, we show that these impacts are concentrated in mobile money accounts, the newer, more complex, and less trusted financial technology.

We study the asset allocation and investment performance of U.S. private foundations that support the charitable sector. Large foundations generated positive risk‐adjusted returns before 2008, driven by early access to private equity and venture capital funds, but have underperformed since. The median foundation underperforms by more than 100 bps. Foundations with concentrated stock holdings achieve higher returns but assume more risk. Due to the constraints imposed by the 5% minimum spending rule and accommodating monetary policy, foundations increase risk‐taking and reach for yield. Over time, a conservative asset allocation decreases real wealth, reducing charitable giving.

I propose a dynamic equilibrium model of rental markets that endogenously gives rise to defaults on rents and evictions. In the model, eviction protections make it harder to evict delinquent renters, but higher default costs to landlords increase equilibrium rents. I quantify the model using micro data on evictions, rents, and homelessness. I find that stronger eviction protections exacerbate housing insecurity and lower welfare. The key empirical driver of this result is the persistent nature of risk underlying rent delinquencies. Rental assistance reduces housing insecurity and improves welfare because it lowers the likelihood that renters default ex ante.

We classify the race of over 160,000 U.S. founders and investors and study the venture capital (VC) funding gap for Black entrepreneurs. Only 3.1% of VC‐funded startups are Black‐owned, and they raise half as much VC funding as others. We attribute much of this gap to Black founders having fewer traditional success markers, like patents or entrepreneurial experience. This disparity also affects matching: Black VC partners invest more in Black founders, and these investments have higher successful exit rates. We attribute this outperformance to lower information asymmetries due to network overlap and “screening discrimination,” whereby Black VCs better differentiate among Black founders.
