Abstract In an infinitely-lived framework, taxing capital income may be growth and welfare enhancing when it allows for correcting distorting externalities in the competitive equilibrium allocation. This is the case when public capital is subject to congestion by private capital or total income [Fisher and Turnovsky (1998)] or when government expenditure exerts an external effect on physical capital [Corsetti and Roubini (1996)]. However, none of these features appear in simple one-sector endogenous growth models with public capital. Alternatively, we consider certain realistic fiscal policy constraints in a simple one-sector growth model with productive and unproductive public expenditures, to show that raising revenues through factor income taxes may be preferred to using lump-sum taxes.engtechnical reporthttps://www.ucm.es/icaeopen accessImpuestos sobre la rentaFinanciación gasto públicocrecimiento endógenoHacienda Pública5301 Política Fiscal y Hacienda Publica Nacionales
