Improvements in productivity are necessary to effectively increase economic growth in the long term. The literature emphasizes a positive correlation between firm-level innovation and productivity gains. It is unsurprising, then, that policy makers and researchers widely acknowledge that...

We estimate a model of international technological spillovers that allows for both international and inter-sectoral technology transfer, as well as international and intersectoral synergies in research and development (R&D). Furthermore we allow for a dynamic interaction in explaining total...

We review the econometric literature on measuring the returns to R&D. The theoretical frameworks that have been used are outlined, followed by an extensive discussion of measurement and econometric issues that arise when estimating the models. We then provide a series of tables summarizing the...

We study four issues in R&D-productivity dynamics: does R&D Granger cause productivity, is there a lag between R&D and its productivity effects, does the potency of R&D vary in timing and magnitude, and what is the role of R&D spillovers and aggregate shocks. The results suggest that R&D causes...

One explanation for declining R&D productivity is demise of industrial research labs. We test that explanation using data from U.S. industrial lab directories from 1921 to 1998. We find the number, size and prevalence of labs have all increased rather than declined. Accordingly, we consider the...

Since governments can influence the demand for a new abatement technology through their environmental policy, they may be able to expropriate innovations in new abatement technology ex post. This suggests that incentives for environmental R&D may be lower than the incentives for market goods...

Since the financial crisis in 2008, slow growth has riddled Europe and the Covid-19 pandemic is amplifying the challenge. Promoting economic growth and transforming to a more knowledge-based industrial structure will be high on the agenda for the coming decades. We study how more and better...

This paper generalizes Segerstrom [5], a dynamic general equilibrium model of endogenous growth through quality improvements in which innovation and imitation are modeled as the outcomes of research and development (R&D) races. Specific factors introduced into the technologies of both R&D...
