Family economics applies basic economic concepts such as production, division of labor, distribution, and decision making to the study of the family. Using economic analysis it tries to explain outcomes unique to family—such as marriage, the decision to have children, fertility, polygamy, time devoted to domestic production, and dowry payments.
The family, although recognized as fundamental from Adam Smith onward, received little systematic treatment in economics before the 1960s. Important exceptions are Thomas Robert Malthus' model of population growth and Friedrich Engels' pioneering work on the structure of family, the latter being often mentioned in Marxist and feminist economics. Since the 1960s, family economics has developed within mainstream economics, propelled by the new home economics started by Gary Becker, Jacob Mincer, and their students. Standard themes include:

fertility and the demand for children in developed and developing countries
child health and mortality
interrelation and trade-off of 'quantity' and 'quality' of children through investment of time and other resources of parents
altruism in the family, including the rotten kid theorem
sexual division of labor, intra-household bargaining, and the household production function.
mate selection, search costs, marriage, divorce, and imperfect information
family organization, background, and opportunities for children
intergenerational mobility and inequality, including the bequest motive.
human capital, social security, and the rise and fall of families
macroeconomics of the family.Several surveys, treatises, and handbooks are available on the subject.
