Research and innovation activities from universities and public research institutes (PRIs) contribute to economic growth in significant ways. Given the hefty investment in R&D in both public and private sectors, it is essential for policy makers to have meaningful, relevant and practical metrics...

This paper deals with the determinants of enterprise creation in the 22 French regions from 1994 to 2003. We then estimate a dynamic panel data model which allows spatial heterogeneity to be modelled and which is compared with a specification without spatial heterogeneity. The estimation results...

The internal rate of return to public investment in agricultural R&D is estimated for each of the continental U.S. states. Theoretically, our contribution provides a way of obtaining the returns to a local public good using Rothbart’s concept of virtual prices. Empirically, we use the spatial...

This paper uses panel data for the 1980-2004 period to estimate the contributions of public research to U.S. agricultural productivity growth. Local and social internal rates of return are estimated accounting for the effects of R&D spill-in, extension activities and road density. R&D spill-in...

Private R&D is a major source of innovation and productivity growth in agriculture worldwide. This paper examines trends and determinants of agricultural R&D in China. Results show that while the public sector monopolized agricultural research until recently, private agricultural R&D has grown...
