Fertility decline in a US population favoring large families: A hazard-model analysis of the effect of sib death on Amish fertility

This paper uses proportional hazards techniques and population data from a directory of the Old Order Amish of the Lancaster, PA settlement. It examines the effect of death of the immediately prior sibling on the risk of childbearing for up to 11 children. Prior research typically has pooled data for maternal cohorts. In contrast, separate models are estimated for each maternal cohort. The results are based on all reported first marriages of Amish women born between 1884–1973 (N = 4066). Hazard models run separately for children of each birth order reveal that net of maternal age and length of the prior birth interval (and other statistical and design controls), the death of the prior sib significantly increases the risk of a subsequent birth for the lower birth orders. Separate models by maternal cohort show that sib death increases the risk primarily for later cohorts. The pattern of effects from child mortality and other variables suggests changes in fertility behavior among the Amish, who have strong, traditional norms opposing contraception and favoring large families.     

The effect of female migration on infant and child survival in Uganda

This article uses data from the 1996 Uganda Demographic and Health Survey to examine whether migration of women improves the survival chances of their children to age five. We expand on prior research by testing not only the hypothesized positive effect of rural-urban migration, but also the effects of other migration stream behaviours on child survival. Results show that up to 10% of children die before age five and within-group differences in mortality exist among urban and rural children depending on their mother's migration status. Only urban-urban migration was significantly related to child survival, compared to rural non-migrants, after controlling for other factors, although other streams of migration (rural-urban, urban-rural, rural-rural) were positively related to child survival. Generally, migration explains a small component of the variance in child survival. Several other factors, including parents' education, household size, household headship, mother's age at birth, duration of breastfeeding, and place of delivery have a significant predictive power on child survival.     

The mismatch between employment and child care in Italy: the impact of rationing

In Italy the women’s participation is among the lowest in Europe. The female employment rate stands almost 13 percentage points below the EU average and 22 below the Lisbon target. One of the most important reasons is related to the characteristics of child care system. We analyze the characteristics of the child care system in Italy and its relationship to the labor market participation decision of mothers. The two decisions are jointly considered in a discrete choice framework, which also allows for simple forms of rationing. We go on to estimate a bivariate probit model of the child care and employment decisions and find evidence that rationing is an important factor in interpreting price effects on utilization rates and employment decisions.

Child mortality, fertility, and human capital accumulation

This article analyzes the impact of decline in child mortality on fertility and economic growth. The study shows that the timing of mortality relative to education is crucial to implications of mortality decline. If child mortality is realized before education starts, an exogenous decline in child mortality leads to a decline in education—a finding that is opposite to those of studies that considered a decline in mortality after the cost of education has been incurred. The work also demonstrates the role of parental human capital in reducing child mortality and the causal link between rising education and declining child mortality.

The effects of family caps on the subsequent fertility decisions of never-married mothers

Family caps seek to reduce fertility among welfare recipients by denying additional cash assistance to recipients who have children while on welfare. A necessary condition for family caps to be an effective policy tool is that welfare recipients respond to financial incentives in making decisions that affect subsequent fertility outcomes. This paper uses data from the 2001 and 2004 panels of the Survey of Income and Program Participation (SIPP) to examine whether welfare mothers respond to the incentive provided by the Aid to Families with Dependent Children/Temporary Assistance to Needy Families (AFDC/TANF) system in determining whether or not to have a second child. The results show no evidence that family caps have an effect on the subsequent childbearing of never married women.

Effects of public education and social security on fertility

Introducing a fertility decision and child care cost into an overlapping generations model with public education and social security, we examine the effects of these public policies on fertility. We show that an increase in income tax, which finances social security benefits and public investment in education, increases fertility. On the other hand, with a constant tax rate, a change in the allocation from social security benefits to public investment in education decreases fertility and, with a constant social security tax, the effect of education tax on fertility is neutral.      

The impact of family policies on fertility in industrialized countries: a review of the literature

This paper examines the theoretical propositions and empirical evidence linking policies and fertility. More specifically, the analysis presented in this paper draws attention to the complex mechanisms that theoretically link policies and demographic outcomes: mechanisms that involve imperfect information and decisions that are rationally bound by very specific circumstances. As to the empirical evidence, studies provide mixed conclusions as to the effect of policies on fertility. While a small positive effect of policies on fertility is found in numerous studies, no statistically significant effect is found in others. Moreover, some studies suggest that the effect of policies tends to be on the timing of births rather than on completed fertility.

The impact of child care on fertility in urban Thailand

Women’s labor force participation in Thailand, particularly in the modem sector, recently has increased in conjunction with rapid declines in fertility. This paper examines whether a relationship exists between child care considerations and fertility decision making among Bangkok women. Although the two-child family has become the norm in recent years, and although most respondents said that ideally they would like to have two children, a high proportion of women surveyed said they planned to only have one child. Women’s work status and type of employment is found to strongly affect the likelihood of having a second birth: those who work at jobs that not only are low-paying but are located in a formal setting are least likely to have a second child. The type of child care for the first child also has an impact: those whose first child is in a less preferred situation are less likely to have a second. Variables measuring the need for and type of child care are found to have greater consequences for fertility than do usual measures of socioeconomic status.     

The impact of changes in child support policy

This paper measures the impact of child support reforms on payments to divorced mothers and welfare participation rates among them. A Stackelberg model of divorced parents’ behavior is calibrated to data from Wisconsin, where child support payments increased from $2,175.35 to $3,431.77 and welfare participation rates decreased from 33.5% to 9% between 1981 and 1992. Results show that new guidelines accounted for 24.4% and improved enforcement for 74% of the increase in payments. Higher payments accounted for a 3.9-percentage-point decline, decreasing welfare benefits an 8.4-percentage-point decline, and the two combined a 15-percentage-point decline in the welfare participation rate.      

The effect of child mortality experience on subsequent fertility: in Pakistan and Bangladesh

Summary This paper presents an empirical analysis of the effects, behavioural and biological, of child mortality experience on subsequent fertility in two South Asian Islamic nations. Data for the investigation came from retrospective pregnancy histories of 2,910 currently married women interviewed in the Pakistan National Impact Survey (1968-69) and from longitudinal vital registration data (1966-2070) of 5,236 women residing in a rural area of Bangladesh collected by the Cholera Research Laboratory. The aim of this study was to assess the importance of the child-replacement motivational response to child death experience after biological effects have been controlled adequately. A common approach employed previously has been to examine cumulative fertility according to child death experience. In Pakistan and Bangladesh, a consistently positive relationship was demonstrated between the number of children ever born and the number of child deaths. This method, however, did not exclude the inverse relationship, the influence of fertility on mortality, nor did it dissect out behavioural from biological effects. Utilizing a measure of subsequent fertility, live-birth-to-live-birth intervals, the study further illustrated another common pitfall. Since the risk of infant death, which leads to shorter birth intervals, is associated with the mother's reproductive history, women with child mortality experience are more likely to experience shorter intervals because of the biological effect of subsequent infant death. Behavioural influences may, therefore, be observed by considering only those birth intervals in which the first-born child survives to the end of the interval. With these limitations controlled, very few, if any, behavioural influences were noted in the Pakistan and Bangladesh data. Median birth intervals in Pakistan varied between 35-43 and 41-42 months, increasing with parity. Within each parity group, no consistent difference was observed between women with and without previous child loss. In Bangladesh, the median birth interval for all women with a surviving infant was 37-2 months. This was shortened to 24-31 months by an infant death. When intervals with infant deaths were excluded, little or no behavioural influence was detected among women of the same parity, but with varying levels of previous child loss. Even without behavioural effects, elimination of infant mortality in Bangladesh would reduce fertility by prolonging the average period of post-partum sterility. In the Bangladesh setting, however, the size of the effect was only about four per cent. This modest effect, more-over, was counterbalanced by an overall increase of net reproduction by seven per cent due to better survivorship of infants.     

The influence of rural-urban migration on migrants' fertility in Korea,Mexico and Cameroon

The paper presents a comparative analysis of the relationship between rural-urban migration and fertility in Korea, Mexico, and Cameroon. Using an autoregressive model, the results show a significant rural-urban migration adaptation effect in Korea and Mexico, a reduction of 2.57 and 1.45 children during the entire childbearing period, respectively, when compared to a rural stayer, even after the effect of selection has been controlled. Rural-urban migration has a very small impact on fertility in Cameroon. The unexpected result for Cameroon is due to the fact that the fertility-increasing effect of urban residency on the improved supply conditions of births, such as reduced infertility, offsets the fertility-depressing effect of urban residency on the demand for births. As a result of the adaptation to urban fertility norms, the number of country-wide births was reduced significantly in Mexico and Korea over the time periods studied.

How the local supply of day-care centers influences fertility in Norway: A parity-specific approach

In order to assess how expansion of day care facilities affects fertility, the Norwegian Family and Occupation Survey of 1988 was linked with individual register-based migration histories and time-series data on day-care coverage rates in all Norwegian municipalities. Many factors affect both the allocation of resources to day-care centers and a woman's probability of giving birth. The local coverage rate is positively associated with the probability of advancing from parity two, after control for geographical region, degree of urbanization and other confounders. This effect of day-care supply, which is significant at low coverage levels, contributed to a moderate rise in third-birth rates after the mid-1970s. However, if the aggregate employment rate for women is also regarded as a confounder, the effect of day care may actually be insignificant. Moreover, the effect fades at higher coverage levels. Finally, there are indications that second- and first-birth probabilities decline with increasing provision of day care. These results suggest that further efforts to improve the supply of private and public day care - which in Norway are likely to be motivated by non-demographic concerns - will have little stimulating effect on fertility, at least if the subsidies and quality of care remain unchanged.     

The effects of teenage fertility on young adult childbearing

Numerous studies of fertility behavior find that an early age at first birth increases the rate of subsequent childbearing. Typically, however, these studies do not account for the possibility of serial correlation in the unobserved determinants of fertility. Using 1979–1992 individual-level data from the National Longitudinal Survey of Youth, this paper employs the Method of Simulated Moments to estimate panel probit models of annual birth outcomes. The panel probit models account for several alternative sources of serial correlation. Estimation reveals that once serial correlation is taken into account, the subsequent fertility effects of early childbearing are either statistically eliminated or reversed.

The perceived impact of child care costs on women’s labor supply and fertility

In a sample of Detroit-area mothers of preschool-aged children interviewed in 1986, one-third reported that child care problems had constrained their employment. Such reports were relatively prevalent among poor women, those without relatives nearby, and those willing to entrust the care of their children to nonfamily members. Only one-tenth of the sample reported a similar child care constraint on fertility, a phenomenon unrelated to income but relatively prevalent among women with strong labor force attachment. The results suggest that policies to increase the supply of child care or to lower its cost could increase female labor supply by a substantial fraction, with an even greater rise among women most at risk of poverty and reliance on public assistance, but probably would not raise fertility significantly.     

The effect of longevity on schooling and fertility: evidence from the Brazilian Demographic and Health Survey

This paper presents microevidence on the effect of adult longevity on schooling and fertility. Higher longevity is systematically associated with higher schooling and lower fertility. The paper looks at the 1996 Brazilian Demographic and Health Survey and constructs an adult longevity variable based on the mortality history of the respondent's family. Families with histories of high adult mortality in previous generations have systematically higher fertility and lower schooling. These effects are not associated with omitted variables and remain unchanged after a large array of factors is accounted for (demographic characteristics, family-specific child mortality, regional development, socioeconomic status, etc.).

The influence of market wages and parental history on child labour and schooling in Egypt

This paper examines the influence of adult market wages and having parents who were child labourers on child labour, when this decision is jointly determined with child schooling, using data from Egypt. The empirical results suggest that low adult market wages are key determinants of child labour; a 10% increase in the illiterate male market wage decreases the probability of child labour by 22% for boys and 13% for girls. The findings also indicate the importance of social norms in the intergenerational persistence of child labour: parents who were child labourers themselves are on average 10% more likely to send their children to work. In addition, higher local regional income inequality increases the likelihood of child labour.

Bargaining over family size: The determinants of fertility in Brazil

Understanding how households make fertility decisions is important to implementing effective policy to slow population growth. Most empirical studies of this decision are based on household models in which men and women are assumed to act as if they have the same preferences for the number of children. However, if men and women have different preferences regarding fertility and are more likely to assert their own preferences as their bargaining power in the household increases, policies to lower fertility rates may be more effectively targeted toward one spouse or the other. In this paper, we test the relevance of the single preferences model by investigating whether men and women's nonwage incomes have the same effects on the number of children in the household. We find that while increases in both the man and woman's nonwage income lower the number of children in the household, an equivalent increase in the woman's income has a significantly stronger effect than the man's. In addition, we find that increases in women's nonwage transfer income have the strongest effects on the fertility decisions of women with low levels of education. The most important policy implication of our results is that policies aimed at increasing the incomes of the least-educated women will be the most effective in lowering fertility rates.
