National policies take varied approaches to encouraging university-based innovation. This paper studies a natural experiment: the end of the "professor's privilege" in Norway, where university researchers previously enjoyed full rights to their innovations. Upon the reform, Norway moved toward...

Using a comprehensive linked employer-employee database from Brazil for the period 1995-2001, we are able for the first time to compare firms founded as employee spinoffs to new firms without parents and to diversification ventures of existing firms entering a new industry. Employee spinoffs are...

In this paper we study how the existence of a functioning market for technology differentially conditions the entry strategy and survival of different types of entrants, and the role of scale, marketing ability and technical assets. Markets for technology facilitate entry of firms that lack...

Cross-field citation probabilities appear to be symmetric for mutually citing fields. Scientific influence is asymmetric within fields, and occurs primarily from top institutions to those less highly ranked. Still, there is significant reverse influence on higher-ranked schools. We also find...

The impact of stronger intellectual property rights in the software industry is controversial. One means by which patents can affect technical change, industry dynamics, and ultimately welfare, is through their role in stimulating or stifling entry by new ventures. Patents can block entry, or...

This paper develops a game-theoretic model that predicts when a university invention is commercialized in a start-up firm rather than an established firm. The model predicts that university inventions are more likely to occur in start-ups when the technology transfer officers (TTOs) search cost...

This paper considers the U.S. Small Business Innovation research (SBIR) program as a policy fostering academic entrepreneurship. We highlight two main characteristics of the program that make it attractive as an entrepreneurship policy: early-stage financing and scientist involvement in...

This paper provides systematic empirical evidence for the distinctive role of universities on local entrepreneurial ecosystems. Assessing the impact of research institutions on entrepreneurship is challenging, given that these institutions are often located in economic and innovation...

This paper analyzes how institutional differences affect university entrepreneurship. We focus on ownership of faculty inventions, and compare two institutional regimes; the US and Sweden. In the US, the Bayh Dole Act gives universities the right to own inventions from publicly funded research,...

We use micro data from Orbis on firm level balance sheets and income statements to document that accounting returns for privately held businesses are dispersed, persistent, and negatively correlated with firm equity. We also show that firms experience large, fat-tailed, and partly transitory...
