Transitional Dynamics in Two-Sector Models of Endogenous Growth.

with Xavier Sala-i-Martin


We analyze the steady state and transitional dynamics of two-sector models of endogenous growth. The necessary conditions for endogenous growth imply that transitions depend only on a measure of the imbalance between the two sectors such as the ratio of the two capital stocks.

We use the Time-Elimination Method to analyze the transitional dynamics. Three main economic forces drive the transition: a Solow effect, a consumption smoothing effect and a relative wage effect. For plausible parameterizations, the consumption smoothing effect tends to dominate the relative wage effect; transition from relatively low levels of physical capital is accomplished through higher work effort rather than higher savings.
