Abstract

This paper characterizes analytically the saving rate in the Ramsey-Cass-Koopmans model with a general production function when there exists both exogenous and endogenous growth. It points out conditions involving the share of capital and the elasticities of factor and intertemporal substitution under which the saving rate path to its steady-state value exhibits overshooting, undershooting, or is monotonic. Simulations illustrate these interesting dynamics. The paper also identifies the general class of production functions that render the saving rate constant along the entire transition path and hence make the Ramsey-Cass-Koopmans model isomorphic to that of Solow-Swan.
