Résumé

Le but de cet article est de montrer que le mécanisme de sélection naturelle des firmes peut entraver la croissance de la productivité agrégée de l'économie, et ce, contrairement aux résultats suggérés par la littérature théorique existante. Cette dernière considère que le mécanisme de sélection des firmes se base sur les niveaux de productivité de celles-ci. Nous supposons, dans cet article, que les firmes sont hétérogènes par non seulement leurs niveaux de productivité mais aussi par leurs coûts fixes. En outre, en tenant compte d'une possible perte d'expérience pour les firmes inactives, notre étude met clairement en avant un effet négatif de la sortie des firmes, et par là d'une baisse des subventions accordées à celles-ci, sur la croissance de la productivité agrégée tant à court qu'à long terme.

Summary

Summary

The aim of this paper is to show that - on the contrary to the existing theoretical literature- market selection mechanism can slow down the aggregate productivity growth. This literature always presumes that firms differ only by their productivity levels and have the same fixed cost. The two basic ideas in this paper are that both firms' productivity levels and fixed costs are heterogeneous. Moreover, exit of firms leads to a partial loss of knowledge which causes a further loss in productivity. Consequently, we show that exit of firms reduces the aggregate productivity growth both in the short and the long run. As a result, a decease in public subsidies which stimulates exit can be harmful for productivity growth.
