The standard neoclassical growth model with Cobb-Douglas production predicts a monotonically declining saving rate, when reasonably calibrated. Ample empirical evidence, however, shows that the transition paths of most countries’ saving rates exhibit a statistically significant hump-shaped...

This paper takes sustainability to be a matter of intergenerational welfare equality and examines whether an optimal development path can also be sustainable. It argues that the general “zero-net-aggregate-investment” condition for an optimal development path to be sustainable in the sense...

The standard neoclassical growth model with Cobb-Douglas production predicts a mono- tonically declining saving rate, when reasonably calibrated. Ample empirical evidence, however, shows that the transition path of a countrys saving rate exhibits a rising or non- monotonic pattern. In important...
