In this paper we estimate a fertility model based on Easterlin's synthesis framework. The model assumes that not all couples are able to achieve their desired number of living children because of supply constraints and that, for other couples, the number of living children may exceed desired fertility, depending upon child mortality, the level of fertility in the absence of control, and the degree of contraceptive regulation practised. Estimates of the model for samples of women with completed fertility taken from the Philippines (1973) and the United States (1965) indicated that a higher proportion of Filipino women than women in the U.S. were unable to achieve desired fertility because of supply constraints, that levels of fertility control of Filipino women not supply-constrained were lower, and that excess fertility of Filipino women was much higher. Demand-for-children equations based on the constraints model were quite different from those not taking into account the possibility that some women were supply-constrained, or that some women may have had more children than desired.
