Twin births are often used to instrument fertility to address (negative) selection of women into fertility. However recent work shows positive selection of women into twin birth. Thus, while OLS estimates will tend to be downward biased, twin-IV estimates will tend to be upward biased. This is...

We estimate a system of three behavioral equations for Brazilian children and teenagers (school absenteeism, health status and child labor). We relieved the assumption of independence of the disturbance terms of each equation. Moreover, if causality mechanisms between these three components...

We present a dynamic life-cycle model of women's labor supply, marriage, and fertility choices that explicitly incorporates mental and physical health. Correlated mental and physical health production functions are simultaneously estimated, including the endogenous decisions to seek...

In this paper we develop an overlapping generations model in which child care matters for human capital accumulation. We investigate whether an increase in labor supply brought about by a reduction in taxes is always associated with a reduction in parental time devoted to children, which...

The economic theory of fertility choice builds predominantly on the unitary model of the household, in which there is a single household utility function and potential intra-household disagreement is abstracted from. Empirical evidence suggests, however, that many (potential) mothers and fathers...

It takes a woman and a man to make a baby. This fact suggests that for a birth to take place, the parents should first agree on wanting a child. Using newly available data on fertility preferences and outcomes, we show that indeed, babies are likely to arrive only if both parents desire one, and...

Norwegian parents of preschool children make their care choices from a completely different choice set compared to what their predecessor did, say, two decades ago. Now, there is essentially only one type of nonparental care, center-based care, and at the parental side fathers take a more...

We study the Becker and Lewis (1973) quantity quality model of children adding an explicit child care time constraint for parents. They can purchase day care or take care of the children themselves. Our results are: (i) If there is a combination of purchased and own care, the effect of income on...

We analyse a model in which families may either be “traditional” single-earner with caring for the child at home or “modern” double-earner households using market child care. Family policies may favour either the one or the other group, like market care subsidies vs. cash for care....
