We study the 1956 consent decree against the Bell System to investigate whether patents held by a dominant firm are harmful for innovation and if so, whether compulsory licensing can provide an effective remedy. The consent decree settled an antitrust lawsuit that charged Bell with having...

The goal of science is to advance knowledge, yet little is known about its value for marketplace inventions. While important breakthrough technologies could not have been developed without scientific background, skeptics argue that this is the exception rather than the rule, questioning the...

How do licensing and technology transfer influence the spread of General Purpose Technologies? To answer this question, we analyze the diffusion of the transistor, one of the most important technologies of our time. We show that the transistor diffusion and cross-technology spillovers increased...

We analyze the effects of the 1984 breakup of the Bell System on the rate, diversity, and direction of US innovation. In the antitrust case leading to the breakup, AT&T, the holding company of the Bell System, was accused of using exclusionary practices against competitors. The breakup was...

Pass-through determines how consumers respond to taxes. We investigate the impact of imperfect price information on pass-through of commodity taxes. Our theoretical model predicts that the pass-through rate increases with the share of well-informed consumers. Pass-through is higher for the...

We provide the first measurement of knowledge spillovers from venture capital-financed companies onto the patenting activities of other companies. On average, these spillovers are nine times larger than those generated by the R&D investment of established companies. Spillover effects are larger...
