We propose a unique market and social planner solution for a generalized New EconomicGeography and Growth model to highlight the importance of taking account of the existenceof agglomeration externalities in an analysis of market inefficiencies, which allows us to providesome important implications for public policy. This framework among other...

Many economists have long held that market failures create a gap between social and private returns to Research and Development (R&D), thereby limiting private incentives to invest in R&D. However, this common belief that firms significantly underinvest in R&D is increasingly being challenged, leading the rationale behind public support for...

Underlining the numerous externalities and distortions that lead firms to underinvest in R&D, the economic literature largely supports the implementation of financial public aids to private R&D. The proliferation of these aids at different territorial levels and the recent emergence of contrasting arguments concerning their rationale create an...

Most studies evaluating the macroeconomic effects of financial support policies on business-fundedR&D use econometric methods that do not consider the existence of spatial effects, and generate biasedestimates. In this paper, we discus and address this problem using spatial dynamic panel data methods.This allow us to provide new insights on the...

Using a unique database containing information on the amount of R&D tax credits and regional, national and European subsidies received by firms in French NUTS3 regions over the period 2001-2011, we provide new evidence on the efficiency of R&D policies taking into account spatial dependency across regions. By estimating a spatial Durbin model...

Based on a spatial extension of an R&D investment model, this paper measures the macroeconomic impact of theFrench R&D policy mix on business R&D using regional data. Our measure takes into account not only the directeffect of policies but also indirect effects generated by the existence of spatial interaction between regions. Usinga unique...

Public aid for financing innovation, particularly for SMEs, has increased significantly over the last twenty years in France. It is therefore appropriate to ask to what extent aid earmarked for RDI has achieved the goals it was designed for. A review of three recent evaluations of direct RDI aid mainly destined for SMEs concludes that in...
