In order to assess the importance of embodiment, we build up an endogenous growth model in which learning by doing is the engine of both embodied and disembodied technological progress. In sharp contrast to Phelps (1962), we show that a change in the composition of technical change affects the...

This note studies the stochastic stability of the standard AK growth model un- der uncertain output technology. Capital accumulation follows a stochastic lin- ear homogenous differential equation. It’s shown that exponential balanced paths, which characterize optimal trajectories in the...
