We document geographic concentration by both venture capital firms and venture capital-financed companies in three cities - San Francisco, Boston, and New York. We find that firms open new satellite offices based on the success rate of venture capital-backed investments in an area. Geography is...

We examine how exposure of Chinese firms to the Covid-19 shock varied with a cluster index (measuring spatial agglomeration of firms in related industries) at the county level. Two data sources are used: entry flows of newly registered firms in the entire country, and an entrepreneur survey...

We organized business associations for the owner-managers of randomly selected young Chinese firms to study the effect of business networks on firm performance. We randomized 2,800 firms into small groups whose managers held monthly meetings for one year, and into a “no- meetings” control...

This paper examines the importance of buyer-supplier relationships, geography and the structure of the production network in firm performance. We develop a simple model where firms can outsource tasks and search for suppliers in different locations. Low search and outsourcing costs lead firms to...

Clusters are geographic concentrations of industries related by knowledge, skills, inputs, demand, and/or other linkages. A growing body of empirical literature has shown the positive impact of clusters on regional and industry performance, including job creation, patenting, and new business...

Assessing the state of American entrepreneurship requires not simply counting the quantity but also the initial quality of new ventures. Combining comprehensive business registries and predictive analytics, we present estimates of entrepreneurial quantity and quality from 1988-2014. Rather than...

Economic growth is persistently low following a financial crisis, possibly because of a continuing weal banking system. In a financial crisis bank health is significantly damaged. Post-crisis regulatory changes have aimed at restoring bank health, but measuring bank health by Tobin's Q, we find...

The recent fall of labor's share of GDP in numerous countries is well-documented, but its causes are poorly understood. We sketch a “superstar firm” model where industries are increasingly characterized by “winner take most” competition, leading a small number of highly profitable (and...

Using linked employer-employee data for the U.S., we examine whether shocks to firm revenues are transmitted to the earnings of continuing employees. While full insurance is rejected, the elasticity of worker earnings with respect to persistent shocks in firm revenues is small and consistent...

We examine whether startups attract employees with different pecuniary and non-pecuniary motives than small or large established firms. We then explore whether such differences in employee motives lead to differences in innovative performance across firm types. Using data on over 10,000 U.S. R&D...
