Considerable controversy exists among demographers, economists, and sociologists over the causes of fertility change in developing and developed countries. The neoclassical economic approach to fertility is embraced by its supporters because it facilitates the application of sophisticated consumer and household production theory to one of the most private and intimate questions: a couple's reproductive behavior. Despite the theoretical appeal of the economic approach, it has been eschewed by many critics because of its lack of social and institutional context, its neglect of cultural factors, and its requirement of 'rationality'. The integration of social interaction with economic fertility models in this book emerges as a powerful tool to overcome many of these criticisms.
