Product market regulation, innovation and productivity

2014

Several recent policy and academic contributions consider that liberalising product markets would foster innovation and growth. This paper analyses the innovation-productivity relationship at the industry-level for a sample of OECD manufacturing industries. We pay particular attention to the vertically-induced influence of product market regulation (PMR) of key input sectors of the economy on the innovative process of manufacturing and its consequences on productivity. We test for a differentiated effect of this type of PMR depending on whether countries are technological leaders or laggards in a given industry and for a given time period. Contrary to the most widespread policy claims, the …

Trade Liberalization and Heterogeneous Technology Investments

2015

We propose a trade model where heterogeneous firms decide on a productivity-enhancing technology investment. The model analyzes the impact of multilateral trade liberalization on firm- and industry-level productivity. Freer trade increases the incentives to invest in technology by raising export profits. It also dampens these incentives, however, as profits stemming from domestic sales are reduced. Only exporters benefit from the former positive effect. The shape of the distribution of efficiency draws, the level of trade costs and the technology intensity of the industry are key elements removing the ambiguities regarding the net impact of trade liberalization.

Product-market integration with endogenous firm heterogeneity

2021

Abstract This paper proposes a general equilibrium oligopoly model in which firm heterogeneity is endogenously reproduced through technology adoption decisions. The model can explain persistent oligopolistic market structures and prices in spite of free entry and market enlargement. Moreover, strong selection might deteriorate average cost efficiency due to strategic interactions. Integrating identical countries can be welfare-improving. But distributional issues and tensions between welfare and scale economies may arise. The theory can be motivated by recent evidence on oligopolistic market structures resisting globalization forces.

Dynamique Industrielle et Internationalisation des entreprises en France

2022

Les revendications politiques habituelles mettent en avant la sélection des entreprises, la réallocation des ressources ainsi que les parts de marché des entreprises les moins efficaces vers les plus productives comme principales sources de croissance de la productivité. La littérature empirique initiée par la « nouvelle » théorie du commerce, a identifié l’exposition et l’accès aux marchés étrangers comme des moteurs importants de ces deux sources de dynamique industrielle. C’est pourquoi, nous nous intéressons aux liens entre la dynamique industrielle et l’internationalisation des entreprises en mettant l’accent sur le rôle de l’innovation. L’objectif de cette étude est de mesurer la croi…

Libéralisation et innovation : faut-il (vraiment) les associer ?

2015

Collection Cepremap; National audience; Depuis les années 1990, les politiques de soutien à l’innovation suscitent un intérêt toujours croissant. Des travaux influents ont étudié le rôle que pourrait jouer la libéralisation des marchés de biens et services dans les incitations à innover. Ils reposent sur des études empiriques qui tentent de mettre en évidence un lien négatif entre niveau de réglementation et productivité. Leur message est relativement simple : la libéralisation, qui favorise les nouveaux entrants, conduirait les firmes à innover pour échapper à la concurrence dans un contexte de stagnation économique. S’appuyant principalement sur des données sectorielle pour les pays de l’…
