New results on the effect of maternal work hours on children's overweight status: Does the quality of child care matter?

Existing empirical research on child overweight derives mainly from North America and points at rising maternal employment as an explanation for the increasing trend in child weight. These results cannot be replicated in Denmark, where an increase in maternal work hours does not increase the likelihood of weight problems for their children. This paper tests four possible explanations for this difference: (1) the effect of maternal employment on child obesity is heterogeneous and varies according to the country's weight distribution; (2) the quality of child care is on average higher in Denmark; (3) the counterfactual care provided by Danish mothers is of lower quality; and (4) Danish fathers contribute significantly to their children's health. This paper finds evidence consistent with the hypotheses that Danish child care and fathers play a significant role in explaining the absence of a significant relationship between maternal work hours and children's overweight status.     

Quasi-structural estimation of a model of childcare choices and child cognitive ability production

This article evaluates the effects of maternal vs. alternative care providers’ time inputs on children’s cognitive development using the sample of single mothers in the National Longitudinal Survey of Youth. To deal with the selection problem created by unobserved heterogeneity of mothers and children, we develop a model of mother’s employment and childcare decisions. We then obtain approximate decision rules for employment and childcare use, and estimate these jointly with the child’s cognitive ability production function. To help identify our selection model, we take advantage of the plausibly exogenous variation in employment and childcare choices of single mothers generated by the variation in welfare rules across states and over time created by the 1996 welfare reform legislation and earlier State waivers.     

School calendars,child care availability and maternal employment

A year-round calendar redistributes schools days around the year. This paper studies how this redistribution of school days, and therefore child care days available through school, affects maternal employment. The presence of year-round calendars in a district could be correlated with other district level attributes that might affect female employment rates. I therefore use a differencing method that compares the influence of district year-round enrollment on the employment rates of women with school-aged children relative to women whose eldest child is pre-school-aged. Unobserved district factors should affect employment rates of women with school-aged and pre-school-aged children similarly, yet only women with school-aged children should be directly impacted by school calendar. I find that redistributing child care days available through school into shorter intervals over time negatively impacts maternal employment. Among those women with school-aged children, those also having pre-school-aged children have the hardest time adjusting to differences in existing availability.     

Public school availability for two-year olds and mothers' labour supply

French children start public school either the year they turn two or the year they turn three. We evaluate the impact of this unique schooling policy on maternal labour supply. Using a Regression–Discontinuity design, we show that early school availability has a significant employment effect on lone mothers, but no effect on two-parent families. Also we show that the effect grows larger as the child grows older and as the family loses eligibility for child benefits. Finally, we provide some new evidence that school enrolment at the age of two has no adverse effect on children's subsequent educational outcomes.     

Can child care policy encourage employment and fertility?: Evidence from a structural model

We develop a structural model of female employment and fertility which accounts for intertemporal feedback effects between these two outcomes. To identify the effect of financial incentives on employment and fertility we exploit variation in the tax and transfer system, which differs by employment state and number of children. Specifically, we simulate in detail the effects of the tax and transfer system, including child care costs. The model provides estimates of the structural preferences of women that can be used to study the effect of various policy reforms. Results show that increasing child care subsidies, conditional on employment, increases the labor supply of all women as well as the fertility rates of the childless and highly educated women.     

UNIVERSAL PRESCHOOL PROGRAMS AND LONG-TERM CHILD OUTCOMES: A SYSTEMATIC REVIEW

What are the long-term effects of universal preschool programs on child outcomes? We review 26 studies using natural experiments to estimate the effects of universal preschool programs for children aged 0–6 years on child outcomes measured from third grade to adulthood. Studies comparing universal preschool with a mix of parental, family, and private modes of care show mixed effects on test scores and on measures related to health, well-being, and behavior. All estimates for outcomes related to adequate primary and secondary school progression, years of schooling, highest degree completed, employment, and earnings indicate beneficial average effects of universal preschool programs. Three of the included studies calculate benefits-to-costs ratios and find ratios clearly above one. Universal preschool tends to be more beneficial for children with low socioeconomic status and there are not consistently different effects for boys or girls. Only three studies compare two alternative types of universal preschool programs in terms of long-term outcomes.     

DOES STUDENT WORK REALLY AFFECT EDUCATIONAL OUTCOMES? A REVIEW OF THE LITERATURE

We review the theories put forward, methodological approaches used and empirical conclusions found in the multidisciplinary literature on the relationship between student employment and educational outcomes. A systematic comparison of the empirical work yields new insights that go beyond the overall reported negative effect of more intensive working schemes and that are of high academic and policy relevance. One such insight uncovered by our review is that student employment seems to have a more adverse effect on educational decisions (continuing studies and enrolment in tertiary education) than on educational performance (test and exam scores).     

Child maturation, time-invariant, and time-varying inputs: their interaction in the production of child human capital

We model the relationship over time between multiple good and bad inputs to the child development production process and the multiple good and bad outcomes which are generated. Doing this avoids several well-known empirical problems associated with construction and use of aggregated inputs and outputs, the assumption of separability among inputs and outputs, and the estimation of reduced forms. Using time-demeaned data for a balanced panel of families from the National Longitudinal Survey of Youth?CChild Sample for 1994?C2000, we estimate an output-oriented directional distance function that simultaneously relates good and bad inputs from home, school, and environment, to good and bad outcomes, measured as children??s math and reading test scores as well as parent-reported behavior problems. We are able for the first time to compute partial effects among endogenous outputs. Recovering consistent estimates of time-invariant coefficients using a second-stage estimator, we find that some time-invariant variables are significant. We also measure productivity growth, technical change, efficiency change, and technical efficiency. Children??s productivity growth is highest at age 5?years and diminishes thereafter. Finally, we investigate the effect on these estimates of the choice of alternative direction vectors for the good and bad outputs.     

Child-custody reform, marital investment in children, and the labor supply of married mothers

Research on child custody primarily focuses on the well-being of children following divorce. We extend this literature by examining how the prospect of joint child custody affects within-marriage investment in children through changes in household bargaining power. Variation in the timing of joint-custody reforms across states provides a natural-experiment framework with which to examine within-marriage investment in children. The probability of children's private school attendance declines by 12% in states that adopt joint-custody laws. We also find evidence linking joint-custody reform to higher rates of labor force participation for married mothers, which may indicate less time devoted household production.     

Impact of Sibship Size,Birth Order and Sex Composition on School Enrolment in Urban Turkey*

This paper investigates, in a unified framework, the effects of sibship size, birth order and sibling sex composition on children's school enrolment in urban Turkey. We utilize an instrumental variable estimation method to address parents’ joint fertility and schooling decisions using twin births as instruments. We find no causal impact of sibship size on school enrolment. However, there is evidence for a parabolic impact of birth order where middle‐born children fare worse. Sex composition of siblings matters only for female children. Our finding that birth order and sibling sex composition matter more for poorer households suggests that scarce financial resources play an important role in bringing about the sibling composition effects.     

Smoking Habits: Like Father,Like Son,Like Mother,Like Daughter?*

We use instrumental variable methods to investigate whether the impact of parental smoking habits on their children's smoking decisions is a causal one. We find suggestive evidence of same‐sex role models in two‐parent households: mothers play a more crucial role in determining their daughters’ smoking decisions, whereas fathers’ smoking habits are primarily imitated by their sons. This same‐sex parent–child link is no longer at play for teenagers living in single‐mother households, for whom the influence of their only cohabiting parent turns out to be predominant independently of gender.     

An Analysis of Kin-Provided Child Care in the Context of Intrafamily ExchangesLinking Components of Family Support for Parents Raising Young Children

Little is known about why parents choose kin-provided child care and less is known about how kin-provided child care is related to other forms of in-kind support from relatives close-at-hand. Previous models of the choice of kin-provided child care assumed that the presence of other forms of in-kind support from relatives nearby was inconsequential to estimating effects of economic and demographic factors on the decision to use kin-provided child care. Using data from the National Longitudinal Survey of the Class of 1972, this study shows that this assumption is incorrect because use of kin-provided child care and intrafamily in-kind resource exchanges are interrelated. When the association between use of kin-provided child care and the presence of other family in-kind exchanges is ignored, the study shows that estimated effects for income, the price of child care, and maternal characteristics are underestimated. The findings provide a better understanding of why parents choose kin-provided child care by confirming that this decision is a part of a larger set of parental decisions about involvement in resource exchanges within extended families. My findings support recent child care bills aiming to increase parental choice of child care provider, broaden the definition of a provider to include non-coresident relatives, and expand price subsidies for kin-provided child care.     

Who benefits from privileged peers? Evidence from siblings in schools

By comparing siblings attending the same school at different points in time, we investigate whether the effect of peer quality on long-term labor market outcomes varies with parental background. We find that exposure to better peers—who have higher mean parental education—increases lifetime earnings of disadvantaged students, coming from families with low parental education, but penalizes privileged students from better educated families. These results suggest that desegregation policies that allocate disadvantaged students to schools with better peers produce long-term benefits. We discuss mechanisms and show that human capital accumulation, ordinal rank and network effects contribute to explain our findings.     

Targeting fertility and female participation through the income tax

We evaluate the effect of a 2003 reform in the Spanish income tax on fertility and the employment of mothers with small children. The reform introduced a tax credit for working mothers with children under the age of three, while also increasing child deductions for all households with children. Theoretically, given the interplay of these two components, the expected effect of the reform is ambiguous on both outcomes. We find that the combined reforms significantly increased both fertility (by almost 5%) and the employment rate of mothers with children under three (by 2%). These effects were more pronounced among less-educated women. In addition, to disentangle the impact of the two reform components, we use an earlier reform that increased child deductions in 1999. We find that the child deductions affect mothers' employment negatively, which implies that the 2003 tax credit would have increased employment even more (up to 5%) in the absence of the change in child deductions.     

Labor supply,income, and welfare of the farm household

Considering family labor and hired labor as heterogeneous inputs, we present a theoretical framework in which the optimal decisions of a farm household on on-farm family and hired labor, off-farm labor supply, and leisure are determined uniquely and endogenously. Focusing on two alternative settings with and without off-farm employment constraints, we show that imperfect substitutability between family labor and hired labor is not critical to the separation of household production and consumption. The validity of the separation proposition is shown to depend crucially on whether or not the availability of off-farm job opportunities is limited. We further examine how changes in external economic conditions and government policies affect the time allocation decisions of the household, as well as the composition of household income (i.e., on-farm income and off-farm labor earnings).     

The Effect of Employment while in High School on Educational Attainment: A Conditional Difference‐in‐Differences Approach*

Using American panel data from the National Education Longitudinal Study of 1988, this article investigates the effect of working during grade 12 on attainment. We employ, for the first time in the related literature, a semiparametric propensity score matching approach combined with difference‐in‐differences. We address selection on both observables and unobservables associated with part‐time work decisions, without the need for instrumental variable. Once such factors are controlled for, little to no effects on reading and math scores are found. Overall, our results therefore suggest a negligible academic cost from part‐time working by the end of high school.     

The effect of a large expansion of pre-primary school facilities on preschool attendance and maternal employment

We provide evidence on the impact of a large-scale construction of pre-primary school facilities in Argentina. We estimate the causal impact of the program on pre-primary school attendance and maternal labor supply. Identification relies on a differences-in-differences strategy where we combine differences across regions in the number of facilities built with differences in exposure across cohorts induced by the timing of the program. We find a sizeable impact of the program on pre-primary school participation among children aged between 3 and 5. In fact, we cannot reject the null hypothesis of a full take-up of newly constructed places. In addition, we find that the implicit childcare subsidy induced by the program appears to increases maternal employment.     

Heterogeneous effects of child disability on maternal labor supply: Evidence from the 2000 US Census

Previous research has documented a negative relationship between child disability and maternal labor supply. Because of data limitations, most studies in this literature use broad measures of disability, which may obscure important differences among children with limiting health conditions. This paper presents new evidence on the labor supply of women with disabled children, exploiting disability information provided by 2000 US Census. This large nationally representative sample allows us to test for differences across different types of disabling conditions. We find that accounting for this heterogeneity in conditions is important. Using a broad definition of disability results in small differences between women with and without a disabled child. When we use a more detailed classification, we find larger labor supply reductions for mothers of children with physical disabilities or limitations in their ability to care for themselves. There is less evidence that having a child with either mental or emotional limitations or a sensory impairment is negatively related to employment or weekly hours. We also test for heterogeneous effects related to child age and maternal education. We find no clear pattern with respect to age and some evidence that the relationship between child disability and maternal labor supply is stronger for less educated mothers.
