Theory suggests that the decision to return to employment after childbirth and the decision to breast-feed may be jointly determined. We estimate models of simultaneous equations for two different aspects of the relationship between maternal employment and breast-feeding using 1993-1994 data from the U.S. Food and Drug Administration's Infant Feeding Practices Study. We first explore the simultaneous duration of breast-feeding and work leave following childbirth. We find that the duration of leave from work significantly affects the duration of breast-feeding, but the effect of breast-feeding on work leave is insignificant. We also estimate models of the daily hours of work and breast-feedings at infant ages 3 months and 6 months postpartum. At both times, the intensity of work effort significantly affects the intensity of breast-feeding, but the reverse is generally not found. Competition clearly exists between work and breast-feeding for many women in our sample. [ABSTRACT FROM AUTHOR]

In this paper I use data from the Panel Study on Income Dynamics to examine the relationship between the dependent exemption feature of the United States federal income tax (an unambiguous subsidy to dependents) and the fertility behavior of married couples over the period 1979-1983. The exemption decreases the price of a child to a household, thus having a direct relationship to the timing and/or number of children observed in a family. Conditional logit results support this hypothesis by showing that the exemption has a positive and significant impact on the likelihood of having a birth during the period under study.

Background: Congenital syphilis can cause severe morbidity, including miscarriage and stillbirth, and rates are increasing rapidly within the United States. However, congenital syphilis can be prevented with early detection and treatment of syphilis during pregnancy. Current screening recommendations propose that all women should be screened early in pregnancy, whereas women with elevated risks for congenital syphilis should be screened again later in pregnancy. The rapid increase in congenital syphilis rates suggests that there are still gaps in prenatal syphilis screening., Objective: This study aimed to examine associations between the odds of prenatal syphilis screening and sexually transmitted infection history or other patient characteristics across 3 states with elevated rates of congenital syphilis., Study Design: We used the Medicaid claims data from Kentucky, Louisiana, and South Carolina for women with deliveries between 2017 and 2021. Within each state, we examined the log-odds of prenatal syphilis screening as a function of the mother's health history, demographic factors, and Medicaid enrollment history. Patient history was established using a 4-year lookback period of the Medicaid claims data; in state A, sexually transmitted infection surveillance data were used to improve the sexually transmitted infection history., Results: The prenatal syphilis screening rates varied by state, ranging from 62.8% to 85.1% of deliveries to women without a recent history of sexually transmitted infections and from 78.1% to 91.1% of deliveries to women with a previous sexually transmitted infection. For the main outcome of syphilis screening at any time during pregnancy, deliveries associated with previous sexually transmitted infections had 1.09 to 1.37 times higher adjusted odds ratios of undergoing screening. Deliveries to women with continuous Medicaid coverage throughout the first trimester also had higher odds of syphilis screening at any time (adjusted odds ratio, 2.45-3.15). Among deliveries to women with a previous sexually transmitted infection, only 53.6% to 63.6% underwent first-trimester screening and this rate was still just 55.0% to 69.5% when considering only deliveries to women with a previous sexually transmitted infection and full first-trimester Medicaid coverage. Fewer delivering women underwent third-trimester screening (20.3%-55.8% of women with previous sexually transmitted infection). Compared with deliveries to White women, deliveries to Black women had lower odds of first-trimester screening (adjusted odds ratio, 0.85 in all states) but higher odds of third-trimester screening (adjusted odds ratio, 1.23-2.03), potentially impacting maternal and birth outcomes. For state A, linkage to surveillance data doubled the rate of detection of a previous sexually transmitted infection because 53.0% of deliveries by women with a previous sexually transmitted infection would not have had sexually transmitted infection history detected using Medicaid claims alone., Conclusion: A previous sexually transmitted infection and continuous preconception Medicaid enrollment were associated with higher rates of syphilis screening, but Medicaid claims alone do not fully capture the sexually transmitted infection history of patients. The overall screening rates were lower than would be expected given that all women should undergo prenatal screening, but the rates in the third trimester were particularly low. Of note, there are gaps in early screening for non-Hispanic Black women who had lower odds of first-trimester screening when compared with non-Hispanic White women despite being at elevated risk for syphilis., (Copyright © 2023 Elsevier Inc.

"In this paper we estimate the impact of the [U.S.] federal individual income tax on the timing of marital decisions.... Using household data from the Panel Study on Income Dynamics, we estimate various models of the probability of delaying marriage as a function of the change in tax burden caused by marriage (as well as several other variables). We find that there is a significant positive relationship between the marriage penalty in a year and the probability of delaying marriage until the following year. The magnitude of the effect, however, is small.", (excerpt)

In this paper we examine the impact of the resource of children and of their parents on the children's transition to residential and financial independence. Previous studies of this transition focused primarily on the impact of family structure and parent-child relationships on the decision to leave home, but much less in known about the role of economic factors in the transition to independence. Using data from the Panel Study of Income Dynamics (PSID) for the period 1968-1988, we estimate discrete-hazard models of the probability of achieving residential and financial independence. We find that the child's wage opportunities and the parents' income are important determinants of establishing independence. The effect of parental income changes with the child's age. We also find some evidence that federal tax policy influences the decision to become independent, although the magnitude of this effect is quite small.

"This paper discusses new empirical evidence on the role of income tax incentives in marital decisions [in the United States]. Time-series evidence suggests that taxes have a small but statistically significant effect on the aggregate marriage rate; however, this evidence is sensitive to the time period and the measure of marriage. Additional evidence, based on household longitudinal data, indicates that the probability of marriage falls and that of divorce rises with an increase in the so-called marriage tax, and that the timing of marriage (though not of divorce) is also affected by taxes. In short, there is strong evidence that taxes affect some marital decisions.", (excerpt)
