Abstract
We present a neoclassical model of the effects of contraception on fertility. Demands for sex and children are derived in a standard consumer problem with the addition of a fertility constraint. We evaluate the effect of shocks to contraceptive efficacy on fertility in the model and then extend to include Becker's quality of children variable in a general model of fertility. We find that positive shocks to contraceptive efficacy generally increase demand for sex and decrease fertility, though fertility may increase for some households. The model provides theoretical support for the robust empirical findings on the power of the Pill.
