Abstract:
This paper examines whether the Solow model of economic growth and steady state income is supported
by available cross-section data. The paper argues that while income per worker is correlated positively
with investment in capital (both physical and human) and negatively with population growth, a simple
log-linear empirical model derived from the Cobb-Douglas production function oversimplifies these
relationships. A nonlinear specification is presented as an alternative. Estimation of the nonlinear
specification shows that for the period 1960-2000, the strongest marginal effects of education occur in
countries where education levels are already relatively high.
