Abstract

. In this paper we investigate the trade‐off faced by regulators who must set a price for an intermediate good somewhere between the marginal cost and the monopoly price. We utilize a growth model with monopolistic suppliers of intermediate goods. Investment in innovation is required to produce a new intermediate good. Marginal cost pricing deters innovation, while monopoly pricing maximizes innovation and economic growth at the cost of some static inefficiency. We demonstrate the existence of a second‐best price above the marginal cost but below the monopoly price, which maximizes consumer welfare. Simulation results suggest that substantial reductions in consumption, production, growth, and welfare occur where regulators focus on static efficiency issues by setting prices at or near marginal cost. JEL Classification: D42, D61, D92, O38 Régulation du prix optimal dans un modèle de croissance où existent des fournisseurs monopolistes de biens intermédiaires. Dans ce mémoire, on enquête sur la relation d’équivalence à laquelle les régulateurs doivent faire face au moment de définir le prix quelque part entre le niveau du coût marginal et le niveau du prix de monopole. On utilise un modèle de croissance dans le cas où existent des fournisseurs monopolistes de biens intermédiaires. Des investissements dans l’innovation sont nécessaires pour produire un nouveau produit intermédiaire. La tarification au coût marginal décourage l’innovation alors que la tarification au niveau du prix de monopole maximise l’innovation et la croissance au prix d’une certaine inefficacité statique. On montre que l’existence d’un prix qui est un optimum de second ordre et se situe au‐dessus du coût marginal mais au dessous du prix de monopole maximise le niveau de bien‐être des consommateurs. Des résultats de simulation suggèrent que des réductions substantielles dans la consommation, la production, la croissance, et le niveau de bien‐être se produisent quand les régulateurs sont focalisés sur les problèmes d’efficacité statique et fixent les prix au niveau (ou près du niveau) du coût marginal.
