An Empirical Analysis of Life Cycle Fertility and Female Labor Supply.
This paper examines household fertility and female labor supply over the
life cycle. The authors investigate ho w maternal time and market inputs,
and benefits children yield their parents, vary with their ages and
influence female labor supply and c ontraceptive behavior. Their
econometric framework combines a female labor-supply model and a
contraceptive choice index function and allo ws conceptions not to be
perfectly controllable. Using data from the Panel Study of Income
Dynamics, they estimate these equations and tes t alternative
specifications. The findings suggest that parents canno t perfectly
control conceptions and variations in child care costs af fect the spacing
of births. Copyright 1988 by The Econometric Society.
