Recent estimates of the effects of tax reforms in the presence of human capital differ greatly. This paper examines which model features and parameter values are critical for the conclusions about the effects of tax changes. I find that the conflicting results of the previous literature are in...

Since 1950, U.S. educational attainment has increased substantially. While the median student in 1950 dropped out of high school, the median student today attends some college. In an environment with ability heterogeneity and positive sorting between ability and school tenure, the expansion of...

The fraction of persons holding a college degree differs nearly two-fold across U.S. states. This paper documents data related to state educational attainment differences and explores possible explanations. It shows that highly educated states employ skillbiased technologies, specialize in...

A number of recent papers have investigated the growth effects of tax reforms in the context of neoclassical growth models where growth is due to human capital accumulation. Stokey and Rebelo (1995) show that the predicted growth effects disagree to a striking extent and are highly sensitive to...

International migration can be viewed as a natural experiment, placing a worker into a different economic environment while holding his human capital endowment fixed. Migration data therefore provide an opportunity to learn not only about the economic forces underlying migration, but also about...

The literature on the growth effects of flat rate taxes focuses entirely on models with infinite horizons and constant returns to private inputs in human capital accumulation. In contrast, the traditional human capital literature assumes finite lifetimes and, based on microeconomic evidence,...

This paper studies quantitative importance of accidental versus intended bequests. Bequests are decomposed into accidental and intended components by comparing the implications of a standard life-cycle model under alternative assumptions about bequest motives. The main finding is that accidental...

College attainment differs nearly two-fold across U.S. states. This paper shows that highly educated states employ skill-biased technologies, specialize in skill-intensive industries, but do not pay lower skill premia. A theory based on agglomeration economies is developed to account for these...

Recent theories of endogenous growth suggest that changes in tax rates may permanently affect growth. However, attempts to quantify these growth effects have reached very different conclusions in spite of a common theoretical framework: the neoclassical growth model with human capital...
