Capital income taxation and economic growth in open economies

Abstract

Can reductions in domestic capital income taxes attract foreign capital and, at the same time, foster economic growth? Using a two-country overlapping generations model with endogenous growth and internationally mobile capital, this paper shows that the effect of domestic capital taxes on the international allocation of capital and on the rate of economic growth do not necessarily go in the same direction. A country can attract capital by reducing its taxes, but this may lower the rate of economic growth depending on the elasticity of saving to the net-of-tax interest rate and on the effect of taxes on domestic factor productivity.
