This paper estimates the relative price sensitivity of individuals' choice of whether to buy computers online versus in retail stores using a new data source on the computer purchase behavior of more than 20,000 people. To estimate the degree of competition between the two channels, the paper...

Early-stage firms utilize venture debt in one-third of financing rounds despite their general lack of cash flow and collateral. In our model, we show how venture debt aligns incentives within a firm. We derive a novel theoretical channel in which runway extension through debt increases firm...

We study the innovation and diffusion of technology at the industry level. We derive the full dynamic paths of an industry's evolution, from birth to its maturity, and we characterize the impact of diffusion on the incentive to innovate. The model implies that protection of innovators should be...

In Silicon Valley's computer cluster, skilled employees are reported to move rapidly between competing firms. This job-hopping facilitates the reallocation of resources towards firms with superior innovations, but it also creates human capital externalities that reduce incentives to invest in...

In this paper, we examine the sources of the productivity growth in the U.S. computer industry from 1978 to 1999. We estimate a joint production model of output quantity and quality that distinguishes two types of technological changes: process and product innovations. Based on the estimation...

The impact of patent pools on the rate and direction of technological change is an open question in both theoretical and empirical studies. Economic theory makes no unequivocal prediction. By contrast, empirical studies of patent pools, to date, have largely concluded that patent pools have been...

We argue that inter-jurisdictional competition in a regionally decentralized authoritarian regime distorts local politicians' incentives in resource allocation among firms from their own city and a competing city. We develop a tournament model of project selection that captures the driving...

We present a mechanism based on managerial incentives through which common ownership affects product market outcomes. Firm-level variation in common ownership causes variation in managerial incentives and productivity across firms, which leads to intra-industry and intra-firm cross-market...

This paper studies how competition affects firms' expectations in a new dynamic general equilibrium model with rational inattention and oligopolistic competition where firms acquire information about their competitors' beliefs. In the model, firms with fewer competitors are less attentive to...
