Innovation, R&D Efficiency and the Impact of the Regulatory Environment: A Two-Stage Semi-Parametric DEA Approach

No 883, Discussion Papers of DIW Berlin from DIW Berlin, German Institute for Economic Research

Abstract: This paper assesses the relative efficiency of knowledge production in the OECD using a nonparametric DEA approach. Resources allocated to R&D are limited and should therefore be used efficiently given the institutional and legal constraints. This paper presents efficiency scores based on an intertemporal frontier estimation for the period 1995 to 2004 and analyzes the impact of the regulatory environment using the single bootstrap procedure suggested by Simar and Wilson (2007). The empirical evidence supports the hypothesis that barriers to entry, aimed at reducing competition, lower research efficiency by attenuating the incentive to innovate and to allocate resources efficiently.
