Technological Progress and Optimal Income Taxation
Insook Lee (李仁淑)

ABSTRACT

Facing technological progress, how should a government reform income taxation? To address this question, optimal capital and labor income taxation is obtained for an economy of heterogeneous individuals. Technological progress raises optimal capital income tax rate and lowers optimal average marginal labor income tax rate if it is capital-biased by increasing relative capital productivity. Technological progress does the opposite if it is labor-biased by decreasing relative capital productivity. Neither capital-biased nor labor-biased technological progress affects optimal slope of labor income tax rate schedule. Technological progress does not affect optimal income taxation if it is unbiased by preserving relative capital productivity.
