Tracing Mobile Inventors – The Causality between Inventor Mobility and Inventor Productivity

This paper analyzes the causality between inventor productivity and inventor mobility. The results show that the level of education has no influence on inventor productivity. Making use of external sources of knowledge, on the contrary, has a significant effect on productivity. Finally, firm size has a positive impact on productivity. Firm size also influences inventor mobility, although negatively. Whereas existing research implicitly assumes causality to point in one direction, this study ex-ante allows for a simultaneous relationship. To deal with the expected endogeneity problem, instrumental variables techniques will be employed. Results show that mobile inventors are more than four times as productive as non-movers. Whereas mobility increases productivity, an increase in productivity decreases the number of moves

Institutionalized Incentives for Ingenuity – Patent Value and the German Employees’ Inventions Act

Germany is one of few countries in which the monetary compensation for inventors is not only determined by negotiations between employer and employee-inventor, but also by relatively precise legal provisions. In this paper, we describe the characteristics of the German Employees’ Inventions Act (GEIA) and discuss which incentives it creates. We rely on responses from a recent survey of 3,350 German inventors to test hypotheses regarding this institution. We conclude from our data that the law creates substantial monetary rewards for productive inventors. The qualitative responses from our survey confirm this view, but also point to a number of dysfunctional effects

Everything you Always Wanted to Know About Inventors (But Never Asked): Evidence from the PatVal-EU Survey

Based on a survey of the inventors of 9,017 European patented inventions, this paper provides new information about the characteristics of European inventors, the sources of their knowledge, the importance of formal and informal collaborations, the motivations to invent, and the actual use and economic value of the patents

Does Mobility Increase the Productivity of Inventors?

Although labor mobility has been recognized as a key mechanism for transferring tacit knowledge, prior research on inventors has so far hardly discussed the impact of a move on inventive performance. Additionally, existing research has neglected the differences in gains from a move between high and lower performing inventors. This paper adds to the current R&D literature by presenting a jointly estimated quantile regression to compare the coefficients of the explanatory variables at different points of the performance distribution. Additionally, dummy variables are used to compare inventive performance prior and in the aftermath of a move. Results reveal that inventors at the upper end of the performance distribution are better able to benefit from a move to draw level with or to overtake non-movers in the post-move period. Whereas at the bottom of the performance distribution a higher level of education has a positive impact on inventive performance, education does not matter significantly at the upper end of the performance distribution. Data for the analysis was derived from a survey of German inventors (N = 3,049)

What Inspires Leisure Time Invention?

This paper seeks to understand the intriguing but only sparsely explored phenomenon of “leisure time invention,” where the main underlying idea for the new product or process occurs when the inventor is away from the workplace. We add to previous research by focussing on the inventive creativity of the individual researcher, and reassessing the image of researchers inventing during unpaid time – who have often been dispatched as “hobbyists”. Based on the responses from a survey of over 3,000 German inventors, we tested hypotheses on the conditions under which leisure time invention is likely to arise. Results suggest that the incidence of leisure time invention is positively related to exposure to a variety of knowledge inputs – but, surprisingly, not to the quality of prior inventive output. Leisure time inventions are more frequently observed in conceptual-based technologies than in science-based technologies, in smaller R&D projects, and in externally financed R&D projects
