This paper augments the Solow-Swan model of economic growth to include
the share of the labour force working outside the agricultural sector
as a labour augmenting variable in the aggregate production function.
The cross-country empirical results suggest that transferring labour
from the agricultural sector to other sectors of the economy is associ
ated with economic growth. This result is robust to using instrumental
variables to control for the potential endogeneity of the relative si
ze of the agricultural labour force.
