Cb. Mulligan et X. Salaimartin, TRANSITIONAL DYNAMICS IN 2-SECTOR MODELS OF ENDOGENOUS GROWTH, The Quarterly journal of economics, 108(3), 1993, pp. 739-773
We analyze the steady state and transitional dynamics of two-sector mo
dels of endogenous growth. The necessary conditions for endogenous gro
wth imply that transitions depend only on a measure of the imbalance b
etween 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 co
nsumption smoothing effect, and a relative wage effect. For plausible
parameterizations the consumption smoothing effect tends to dominate t
he relative wage effect; transition from relatively low levels of phys
ical capital is accomplished through higher work effort rather than hi
gher savings.
