Using a new dataset encompassing more than 2,200 inventions made by Max Planck Society researchers from 1980 to 2004, we explore how licensee and technology characteristics affect the licensing and commercialization of technologies from public research. We find no evidence that spin-offs and...

This paper analyzes how companies of immigrant entrepreneurs in knowledgeintensive industries differ from companies of native entrepreneurs with respect to start-up characteristics, firm survival and innovative performance. I focus on immigrants from the "recruitment countries" of south and...

This study shows for a large sample of R&D-active manufacturing firms that collaborative R&D has a positive effect on firms' patenting in terms of both quantity and quality. When distinguishing between alliances that aim at joint creation of new knowledge and alliances that aim at exchange of...

Patent data provide a rich set of information which can be used for comparative studies and trend analysis. The paper presents a systematic overview of the most appropriate tools methodologies that are available for determining the technological specialization of countries. Such analysis...

The growing importance of technology relevant non-publication output of university research has come into the focus of policy-makers' interest. A fierce debate arose on possible negative consequences of the increasing commercialization of science, as it may come along with a reduction in...

This paper presents estimates of the depreciation rate of innovations using survey data on revenues associated with Australian patents. Its novelty is twofold. First, it relies on direct observation of the revenue streams of inventions. This is in sharp contrast with previous studies, which all...

Previous research has expressed concerns about firms engaging less in basic research. We contribute to this debate by studying trends in the scientific publishing activities of firms located in Germany. Our results do not confirm a declining trend in raw numbers with numbers indicating that...

This article reviews the impact of intellectual property (IP) protection on foreign direct investment (FDI) by multinational enterprises (MNEs) in developing countries. Applying different panel data techniques to a newly-created comprehensive FDI/IP dataset of 31 Swiss MNEs investing into 53...

We study the effect of a firm winning an additional H-1B visa on the firm’s outcomes, by comparing winning and losing firms in the Fiscal Year 2006 and 2007 H-1B visa lotteries. We match administrative data on the participants in these lotteries to the universe of approved U.S. patents, and to...

We develop and test a model of the patenting and R&D decisions of an innovating firm whose researcher-employees sometime quit to join or start a rival. In our model, the innovating firm patents to protect itself from its workers. We show theoretically that the risk of a scientist's departure...
