For a given set of labor market institutions, the rate of frictional unemployment depends on the evolution of the pool of job-seekers. Unemployment rises with the growth rate of labor supply that is proportionate to the rate of population growth. If economic growth is semi-endogenous, the...

Recently, Jones (2002} and Barro and Sala-í-Martin (2004) pointed out that the neoclassical growth model with a Cobb-Douglas technology has a closed-form solution. This note makes a similar remark for the Malthusian model: I develop and characterize a closed-form solution. Moreover, I emphasize...

Uzawa´s theorem (Uzawa (1961)) is extended to allow for adjustment costs in the process of capital accumulation. A new steady-state growth theorem with adjustment costs establishes that capital-augmenting technical change may arise in steady state. This is in sharp contrast to Uzawa´s original...
