October 2013Upstream Product Market Regulations, ICT, R&D and Productivity
with Gilbert Cette, Jacques Mairesse: w19488
Our study aims at assessing the actual importance of the two main channels usually contemplated in the literature through which upstream sector anticompetitive regulations may impact productivity growth: business investments in R&D and in ICT. We thus estimate what are the specific impacts of these two channels and their shares in total impact as against alternative channels of investments in other forms of intangible capital we cannot explicitly consider for lack of appropriate data such as improvements in skills, management and organization. For this, we specify an extended production function relating productivity explicitly to R&D and ICT capital as well as to upstream regulations, and two factor demand functions relating R&D and ICT capital to upstream regulations. These relations are...
November 2010Do Product Market Regulations in Upstream Sectors Curb Productivity Growth? Panel Data Evidence for OECD Countries
with Renaud Bourl├Ęs, Gilbert Cette, Jacques Mairesse, Giuseppe Nicoletti: w16520
Based on an endogenous growth model, we show that intermediate goods markets imperfections can curb incentives to improve productivity downstream. We confirm such prediction by estimating a model of multifactor productivity growth in which the effects of upstream competition vary with distance to frontier on a panel of 15 OECD countries and 20 sectors over 1985-2007. Competitive pressures are proxied with sectoral product market regulation data. We find evidence that anticompetitive upstream regulations have curbed MFP growth over the past 15 years, more strongly so for observations that are close to the productivity frontier.
