Abstract: Abstract This paper analyzed the evolution of human capital inequality in an overlapping generations model that incorporates Stone–Geary preferences with subsistence consumption. Many studies have revealed an inverted U-shaped relationship between human capital inequality and economic development, namely the human capital Kuznets curve. However, this curve is inconsistent with empirical evidence in a US context, where the data suggest a U-shaped evolution of earnings inequality. We show that the utility function has an increasing elasticity of substitution, and the time allocated to human capital investment decreases in the early stages of human capital accumulation and increases afterward. Thus, we obtain a U-shaped curve for human capital inequality if the elasticity of substitution is large. Eventually, decreasing returns to human capital accumulation reduce inequality.
