چکیده

We introduce public capital and public services as inputs in an endogenous growth model. We show that the growth rate depends on the apportionment of tax revenues between the accumulation of public capital and the provision of public services. When public spending is financed by proportional income taxes, the growth rate, the level of public spending as a proportion of GDP, the level of investment in public capital as a proportion of total public spending, and the level of private investment as a proportion of total private spending all are lower in the equilibrium outcome than in the optimal outcome. JEL classification: E62, O40 Politique fiscale, croissance à long terme et bien-être dans un modèle stock/flow de biens publics. Les auteurs introduisent du capital public et des services publics comme intrants dans un modèle de croissance endogène. On montre que le taux de croissance dépend de l’allocation des revenus de la fiscalité entre l’accumulation de capital public et la fourniture de services publics. Quand les dépenses publiques sont financées par un impôt proportionnel sur le revenu, le taux de croissance, le niveau de dépenses publiques en pourcentage du PIB, le niveau d’investissement en capital public, et le niveau d’investissement privé en proportion de la dépense totale privée sont tous moins élevés au niveau d’équilibre que ce qui serait le résultat optimal
