Abstract
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.
