Birth order effects and time allocation.

"In this paper, a model is developed in which the explanation for birth-order effects does not rely on absence of capital markets, but follows from optimal allocation of parental time and goods among children over the childrearing years. The model yields two key results, which are then tested using 1967-1968 household survey data from urban Colombia.... It is shown that first and last-born children of mothers who do not work have an advantage over middle-borns.... At the same time, as predicted, there are no differences by birth order among children of working mothers. The persistence of birth-order effects even in high-income families indicates that such effects are at least in part due to the time constraint modelled; this is a strong result given the possibility of better substitutes for mother's time than allowed for in the model, and the likelihood that high-income families are able to purchase better substitutes."

Economic analyses of rapid population growth.

"Discussion of the macroeconomic consequences of rapid population growth is organized into three schools: pessimists, optimists, and the recent revisionists. For the revisionists, differing views are presented about the pervasiveness and relevance of market failures, such as the negative externalities of childbearing, and about the ability of families and institutions to adjust rapidly to changes brought on by rapid population growth. A welfare economics approach is used to review the merits of various public policies to reduce fertility, including public financing of family planning services and taxes and incentives associated with childbearing." The focus is on developing countries.
