This paper explores the stability of the stationary state for a dynamic growth model with wealth and human capital accumulation. Knowledge is created through research and learning-by-doing, while the time allocation between labor and leisure is endogenized. We analyze the model in both its...

Ghana’s economy was identical to South Korea’s economy in the 1960s. Since the 1970s, however, Ghana’s economy has substantially lagged. To explain Ghana’s poor long-run economic growth, we build a neoclassical growth model to primarily examine the role of Ghana’s barriers to physical...

Estimates of the effect of education on GDP (the social return) have been hard to reconcile with micro evidence on the private return to schooling.

This paper develops a classical-Marxian macroeconomic model to examine the growth and distributional consequences of education. First, the role of education in skill formation is considered and it is shown that an expansion in education will promote growth and have beneficial distributional...

When types of workers are imperfect substitutes, the Mincerian rate of return to human capital is negatively related to the supply of human capital. We work out a simple model for the joint evolution of output and wage dispersion. We estimate this model using cross-country panel data on GDP and...
