Endogenizing labour supply leads to fundamental changes in the equilibrium
structure of the AK growth model of a small open economy. The balanced grow
th equilibrium is described by two tradeoff loci relating the equilibrium g
rowth rate to the fraction of time devoted to leisure. The implications of
endogenous labour supply for fiscal policy are addressed The effects of dis
tortionary taxes and government expenditure on the equilibrium growth-leisu
re (employment) tradeoff are analysed. The responses contrast with both tho
se of a closed economy, having an elastic labour supply, and an open econom
y with fixed labour supply. Optimal fiscal policy is also characterized.
