摘要

This paper studies the optimal factor tax incidence in a standard two-sector, human capital-based endogenous growth model elucidated by Lucas (1988). Capital income taxes generate dynamic inefficiency for capital accumulation and labor income taxes create dynamic inefficiency for human capital accumulation. A factor tax incidence is a tradeoff between these two inefficiencies. A switch from capital income taxes to labor income taxes reduces the long-run welfare coming from lower leisure and increases the long-run welfare originated from higher economic growth and higher consumption. Because the representative agent's learning time and human capital are inseparable and thus affect learning activities at the same degree, we find that based on the current US income tax code, it is optimal to first tax capital income, and to resort to taxing labor income only when tax revenue is insufficient to cover government expenditure.
