Abstract: This paper proposes a dynamic economic model of wealth accumulation and human capital accumulation with endogenous education. It is an extension of the Uzawa-Lucas model of a heterogeneous household economy with multiple ways of human capital accumulation. In addition to learning by education in the Uzawa-Lucas model (Uzawa, 1965; Lucas, 1988), we also consider Arrow’s ‘learning by producing’ (Arrow, 1962) and Zhang’s ‘learning by consuming’ (creative learning, Zhang, 2007) in the human capital accumulation equation. The economic system consists of one production sector and one education sector. Households differ in propensity to save, to obtain education, to consume, and in learning abilities. The model describes a dynamic interdependence between wealth accumulation, human capital accumulation, and division of labour with endogenous wealth and income distribution in perfect competition. We simulate the model to demonstrate the existence of equilibrium points and the motion of the dynamic system. We also demonstrate how changes in the propensity to obtain education, the population, the propensity to save, and the education sector’s total productivity affect economic development.
