TY - RPRT AU - Richter, Wolfram F. TI - Taxing Human Capital Efficiently: The Double Dividend of Taxing Non-Qualified Labour More Heavily Than Qualified Labour PY - 2006/Sep/ PB - Institute of Labor Economics (IZA) CY - Bonn T2 - IZA Discussion Paper IS - 2328 UR - https://www.iza.org/publications/dp2328 AB - Assuming decreasing returns to education and the endogenous supply of qualified and non-qualified labour it is shown to be efficient to supplement a consumption tax with positive incentives for education. If the return from education is isoelastic and if the choice is between (i) subsidizing the monetary cost of education and (ii) taxing non-qualified labour income more heavily than qualified labour income while keeping the effective cost of education constant, the latter policy is shown to be second-best efficient. In particular, any tax distortions should be constrained to labour choices while the choice of education should remain undistorted. The result holds for arbitrary utility functions.
