Abstract

The celebrated Uzawa(1961) theorem holds that,on the steady-growth path of neoclassical growth model,technological progress must be purely labor-augmenting rather than capital-augmenting,except the special case where the production function takes the form of Cobb-Douglas. With an augmented Ramsey model,however,we prove in this paper that,when investment has adjustment cost which correlates positively with capital-augmenting technology,the steady state growth path can also embrace capital-augmenting technological progress,even if the production function is not Cobb-Douglas. Our conclusions contribute to the study of steady-state condition of neoclassical growth model,and the understanding of the roles of capital and capital-augmenting technology progress in economic growth.
