In a recent paper, Bloom et al. (2020) find evidence for a substantial decline in research productivity in the U.S. economy during the last 40 years. In this paper, we replicate their findings for China and Germany, using detailed firm-level data spanning three decades. Our results indicate that...

This paper examines how a radical technological innovation affects alliance formation of firms and subsequent network structures. We use longitudinal data of interfirm R&D collaborations in the biopharmaceutical industry in which a new technological regime is established. Our findings suggest...

This chapter summarizes the basic characteristics of patent data as an innovation indicator and reviews some of the recent research using patent data, focusing on major developments since Griliches in 1990 [Griliches, Z. (1990). “Patent statistics as economic indicators: A survey”. Journal...

This paper investigates the effects of employee mobility on industry evolution and technology diffusion by testing a dynamic industry equilibrium model introduced in Franco and Filson (1999). The model focuses on a particular type of employee mobility: researchers can leave existing firms and...

Of the diverse factors motivating technological change, one factor that has received increasing attention in the recent past has been the protection of intellectual property rights. Given fairly recent changes in the international policy ethos where a regime of stronger intellectual property...

We study a two-stage R&D project with an abandonment option. Two types of uncertainty influence the decision to start R&D. Demand uncertainty is modelled as a lottery between a proportional increase and decrease in demand. Technical uncertainty is modelled as a lottery between a decrease and...

An 'incentive subsidy' policy for subsidizing private R & D is proposed that can be more efficient, from a social point of view, than subsidy policies in common use such as a 'normal' subsidy policy (fixed amount granted at project start), and conditional loans (loan is repaid only if project is...

Government subsidized industrial R & D stands for a large and increasing segment of the total R & D conducted. Yet very little is known about the effectiveness of such subsidies. This paper summarizes the empirical literature concerning direct project subsidies, tax credits, and support for...

This paper investigates the determinants of EPO (European Patent Office) patent applications per capita using a panel of 22 OECD countries with data measured as five-year averages for the period 1980-1999. The patent production function is specified as a partial adjustment model and is estimated...

Previous literature provided evidence on financing constraints for investment in R&D activities due to capital market imperfections and special features of R&D investments. Moreover, it has been shown that a shift in capital structure towards more debt, results in a reduction of R&D investments....
