We analyze determinants of access to venture capital for Black founders of high-growth startups. We combine image- and name-processing algorithms with clerical review to identify race for over 100,000 startup founders "at risk" for venture funding. Black founders raise roughly one-third as much...

From 2010 to 2021, 639 US VC-funded firms achieved unicorn status. We investigate why there are so many unicorns and why controlling shareholders give investors privileges to obtain unicorn status. We show that unicorns rely more than other VC-funded firms on organizational capital as well as...

Economic frictions pervade the founding, financing, growing, and exiting of high-growth entrepreneurial firms. This article considers one friction that currently affects a small, but important, set of entrepreneurs: racial and gender discrimination. I first collect facts from a large empirical...

Using an administrative payroll dataset for 2.6 million retail workers, we find that the staggered rollout of a major e-commerce firm's fulfillment centers reduces traditional retail workers' income in geographically proximate counties by 2.4%. Wages of hourly workers, especially part-time...

Despite substantial efforts to help consumers search in more intuitive ways, text search remains the predominant tool for product discovery online. In this paper, we explore the effects of visual and textual cues for search refinement on consumer search and purchasing behavior. We collaborate...

We build a model of online behavioral manipulation driven by AI advances. A platform dynamically offers one of n products to a user who slowly learns product quality. User learning depends on a product's "glossiness,' which captures attributes that make products appear more attractive than they...

We develop and estimate a model of consumer search with spatial learning. Consumers make inferences from previously searched objects to unsearched objects that are nearby in attribute space, generating path dependence in search sequences. The estimated model rationalizes patterns in data on...

We examine the influence of physical proximity on between-startup knowledge spillovers at one of the largest technology co-working hubs in the United States. Relying on the random assignment of office space to the hub's 251 startups, we find that proximity positively influences knowledge...

Solar technologies have been associated with private and social returns, but their technological potential often remains unachieved because of persistently low demand for high-quality products. In a randomized field experiment in Senegal, we assess the potential of three types of quality...

A sender sends a signal about a state to a receiver who takes an action that determines a payoff. A moderator can block some or all of the sender's signal before it reaches the receiver. When the moderator's policy is transparent to the receiver, the moderator can improve the payoff by blocking...
