This paper introduces technological diffusion in the standard Uzawa-Lucas endogenous growth model. We show that the model can be solved analytically in its log-linear approximation. There are three negative eigenvalues, which makes the model's dynamics relatively rich.

This paper considers three natural extensions of the Uzawa-Lucas model. These extensions work with physical capital and one or two types of human capital. There are two or three sectors in which production takes place. We show that the steady-state growth rate of the economy can be analytically...
