Investment in R&D is positively associated with the variance of sales growth and, to a lesser extent, employment growth. The magnitude of this effect has not increased in recent decades, however.

This paper studies the differences in the R&D and innovation behaviour of high-growth firms for 16 EU countries. The results confirm that R&D and innovation are important characteristics for high-growth firms in countries close to the technological frontier, but not for high-growth firms in...

We examine pollution-reducing R&D by a monopoly firm producing a dirty product. In a dynamic framework with hyperbolic discounting, we establish conditions under which the Porter hypothesis goes through, i.e. environmental regulation increases R&D, thus reducing pollution, as well as increasing...

We reconsider Banerjee and Lin [International Journal of Industrial Organization, 2003] by investigating the role of spillovers (or informational flows) for the profitability of input-price contracts in a vertically related industry. We show that spillovers influence the relative magnitude of...

This article models the intertemporal behaviour of a firm that sets product prices and simultaneously invests in R&D. The model shows that the dynamic pricing rule follows the evolution of the production cost and is independent of the evolution of the product quality. Thus, process innovation,...

In this paper we reexamine the relationship between patents and R&D using empirical likelihood estimation. Based on the data of Hall, Griliches, and Hausman (1986) and the specification allowing for endogenous regressors, we found that the contemporaneous effect of R&D is significantly positive,...

This paper examines the transitional dynamics of an R&D-based endogenous growth model with heterogeneous labor and explains the post-war comovement of three variables in the U.S. economy: the skill premium, the share of labor devoted to R&D and the growth rate of labor productivity. This paper...
