September 2016Labour Market Regulations and Capital Intensity
with Gilbert Cette, Jacques Mairesse: w22603
On the basis of a country*industry unbalanced panel data sample for 14 OECD countries and 18 industries covering the years 1988 to 2007, this study proposes an econometric investigation of the effects of the OECD Employment Protection Legislation (EPL) indicator on capital intensity for four capital components, and on the share of employment for two skill components. Our results relying on a difference-in-difference approach are the following: i) positive and significant effects for non-ICT physical capital intensity and the share of high-skilled employment; ii) non-significant effects for ICT capital intensity; and (iii) negative and significant effects for R&D capital intensity and the share of low-skilled employment. These results suggest that firms consider that the strengthening of Em...
October 2014Product and Labor Market Regulations, Production Prices, Wages and Productivity
with Gilbert Cette, Jacques Mairesse: w20563
This study is an attempt to evaluate the effects of product and labour market regulations on industry productivity through their various impacts on changes in production prices and wages. In a first stage, the estimation of a regression equation on an industry*country panel, with controls for country*industry and country*year fixed effects, show that multi-factor productivity is negatively and significantly influenced by both indicators of industrial prices from same industry and weighted average of industrial prices from other industries, and by indicators of country wages weighted by industry labour shares for low and high skilled workers. In a second stage, an economic policy simulation of the implications these results on the basis of their calibration by the OECD product and labour ma...
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 Bourlès, 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.
