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.

Cette conjecture est confirmée empiriquement par l'estimation d'un modèle qui différencie les effets potentiels, sur la productivité globale des facteurs (PGF), d'une concurrence insuffisante dans les secteurs amont selon la distance à la frontière technologique sectorielle. Ces estimations sont réalisées sur un panel de 15 pays de l'OCDE et 20 secteurs d'activité sur la période 1985-2007. La concurrence en amont est mesurée par des indicateurs sectoriels de régulation sur les marchés des biens. Les résultats montrent que, sur les 15 dernières années, les régulations anticompétitives dans les secteurs amont ont affaibli les gains de PGF, tout particulièrement pour les observations proches de la frontière technologique.

We present version 10 of OrthoMaM, a database of orthologous mammalian markers. OrthoMaM is already 11 years old and since the outset it has kept on improving, providing alignments and phylogenetic trees of high-quality computed with state-of-the-art methods on up-to-date data. The main contribution of this version is the increase in the number of taxa: 116 mammalian genomes for 14,509 one-to-one orthologous genes. This has been made possible by the combination of genomic data deposited in Ensembl complemented by additional good-quality genomes only available in NCBI. Version 10 users will benefit from pipeline improvements and a completely redesigned web-interface.
