The Market for Patents in Europe

By using the PatVal-EU dataset we find that the most important determinant of patent licensing is firm size. Patent breadth, value, protection, and other factors suggested by the literature also have an impact, but not as important. In addition, most of these factors affect the willingness to license, but not whether a license actually takes place. We discuss why this suggests that there are transaction costs in the markets for technology. The issue is important because many potential licenses are not licensed suggesting that the markets for technology can be larger, with implied economic benefits.

Individual Entrepreneurial Exit and Earnings in Subsequent Paid Employment

We study earnings of individuals who exit entrepreneurship for paid employment. We find mean (median) positive rewards from entrepreneurship in subsequent paid employment relative to matched employees. Rewards are higher for former entrepreneurs hired in highly innovative sectors. We also find that the performance of the exited firm is a strong predictor of the earnings premium for former entrepreneurs when the firm performed well, while we do not find median discounts for entrepreneurs exiting low performing firms. We use registry data that encompass the population of firms and individuals in the Norwegian economy.

Firm Assets and The Rate of Product Introduction in Open Source Software

Drawing on the resource-based theory of the firm, this paper investigates the role played by firm assets both upstream and downstream, in the software and the hardware dimensions, to explain the rate of product introduction in open source software (OSS). Using a selfassembled database of firms that announced releases of OSS products between 1995 and 2003, we find that the rate of product introduction can be explained by a strong position in software technology and downstream market presence in hardware. Firms with consolidated market presence in proprietary software and strong technological competence in hardware are more reluctant to shift to the new paradigm. The fear of cannibalization, the crucial role of absorptive capacity, and complementarities between hardware and software are plausible explanations behind our findings.
