This paper considers a three-overlapping-generations model of endogeneous growth wherein human capital is the engine of growth. It first contrasts the laissez-faire and the optimal solutions. Three possible accumulation regimes are distinguished. Then it discusses a standard set of tax-transfer instruments that allow for decentralization of the social optimum. Within the limits of our model, the rationale for the standard pattern of intergenerational transfers (the working-aged financing the education of the young and the pension of the old) is seriously questioned. On pure e¢ciency grounds, the case for generous public pensions is rather weak.
