This paper studies the effects of distortionary taxes and public investment in an endogenous growth OLG model with knowledge transmission. Fiscal policy affects growth in two respects: first, work time reacts to variations of prospective tax rates and modifies knowledge formation; second, public spending enhances labour efficiency but also stimulates physical capital through increased savings. It is shown that Ramsey-optimal policies reduce savings due to high tax rates on young generations, and are not necessarily growth-improving with respect to a pure private system. Non-Ramsey policies that shift the burden on adults are always growth-improving due to crowding-in effects: the welfare of all generations is unambiguously higher with respect to a private system, and there generally exists a continuum of non-optimal tax rates under which long-run growth and welfare are higher than with the Ramsey-optimal policy.
