报告简介

We investigate optimal taxation in an endogenous growth model with positional consumption and education spending externalities. Such externalities reinforce their negative effects on investment and education. Internalizing such externalities should tax income and consumption, subsidize investment at the capital-income tax rate, and subsidize education more highly than tax labor income and consumption. Optimal tax-subsidy rates are time-invariant and time-consistent unless government debt exceeds its steady-state ratio to output. Education subsidies or labor-income taxes have ambiguouseffects on schooling time. Investment subsidies increase schooling. The result may explain why the U.S. has higher education attainment and productivity than the OECD average.
