This paper examines the causal effect of childcare provision on grandparents’ health in the United States. We use the sex ratio among older adults’ children as an instrument for grandparental childcare provision. Our instrument exploits that parents of daughters transition to grandparenthood earlier and invest more in their grandchildren than parents of sons. We estimate 2SLS regressions using data from the Health and Retirement Study. The results suggest that providing childcare is detrimental to grandparents’ physical functioning and subjective health. We show that these effects increase with the intensity of grandchild care provision, and the effects are driven primarily by grandmothers. [ABSTRACT FROM AUTHOR]

This study identifies obesity as an important channel through which global warming affects human capital. By analyzing plausibly exogenous year-to-year temperature fluctuations in 152 countries from 1975 to 2016, we find that global warming has significantly increased obesity rates in countries located in temperate zones, while only causing a reduction in a small number of tropical countries. The estimates suggest that a 1 ∘ C increase in the annual mean temperature would result in a worldwide increase in obese adults of 79.7 million, or 12.3%. Similar patterns emerge when examining the effects of temperature bins, seasonal mean temperature, temperature variations, and temperature shocks. Furthermore, we identify substantial heterogeneity in the impact across countries with varying income levels, age structures, and education levels. Finally, by comparing the baseline model with a long-difference model, we demonstrate that long-term adaptation may not significantly mitigate the impact of global warming on obesity in temperate zones.

This paper examines the labour market and health effects of a non-contributory long-term unemployment (LTU) benefit targeted at middle-aged disadvantaged workers. To do so, we exploit a Spanish reform introduced in July 2012 that increased the age eligibility threshold to receive the benefit from 52 to 55. Our results show that men who were eligible for the benefit experience a reduction in injury hospitalisations by 12.9% as well as a 2 percentage points drop in the probability of a mental health diagnosis. None of the results are significant for women. We document two factors that explain the gender differences: the labour market impact of the reform is stronger for men, and eligible men are concentrated in more physically demanding sectors, like construction. Importantly, we also find evidence of a program substitution effect between LTU and partial disability benefits. Our results highlight the role of long-term unemployment benefits as a protecting device for the (physical and mental) health of middle-aged, low-educated workers who are in a disadvantaged position in the labour market.

This paper evaluates the causal effects of mother's and father's education on child-health outcomes in Zimbabwe, exploiting the exogenous variation generated by the 1980 education reform. We use four waves of Demographic and Health Surveys for Zimbabwe and estimate a simultaneous-equation model to take into account possible selection into co-residence between parents and children, endogeneity biases, and parental education sorting. Our results suggest that father's education affects the health outcomes of under-5 children and matters more than that of the mother. These results continue to hold in a number of robustness checks. Moreover, while there is selection into co-residence with the child, this does not affect the causal effect of education on child health. Last, parental educational sorting is also shown to be important. Our findings suggest that not taking the education of both parents into account simultaneously may yield misleading conclusions.

We provide a comprehensive picture of the health effects of social isolation using longitudinal data from 21 European countries. First, using Cox regressions, we find a significant, strong, and robust association between our social isolation index and mortality. The association is much stronger in Eastern European countries. While all of our pooled countries estimates ranged between a 20 and 30% increase in the mortality hazard for the socially isolated that number jumps to 45% for Eastern European countries. We then estimate linear regressions to study the dynamic "value-added" effects of social isolation on health and other mediator outcomes. We find that social isolation at baseline leads to worsening health in subsequent waves along all of the dimensions observed. Up to 13% of the effect of baseline social isolation on mortality can be attributed to the combined one-wave-ahead impact of social isolation on increased frailty, reduced cognitive function, and increased smoking.

This paper studies the effects of immigration on the allocation of occupational physical burden and work injury risks. Using data for England and Wales from the Labour Force Survey (2003–2013), we find that, on average, immigration leads to a reallocation of UK-born workers towards jobs characterised by lower physical burden and injury risk. The results also show important differences across skill groups. Immigration reduces the average physical burden of UK-born workers with medium levels of education, but has no significant effect on those with low levels. We also find that that immigration led to an improvement self-reported measures of native workers' health. These findings, together with the evidence that immigrants report lower injury rates than natives, suggest that the reallocation of tasks could reduce overall health care costs and the human and financial costs typically associated with workplace injuries.

We examine the effect of birth weight on health throughout childhood, adolescence, and early adulthood, focusing on two health outcomes: all-cause and cause-specific hospitalizations and sickness absences. The outcomes are important, not only from a health perspective but also from a labor market perspective, as the inability to fully participate in the labor force due to impaired health is known to have important long-term consequences. Our analysis focuses on differences between siblings, using full-population Swedish register data on cohorts born between 1973 and 1994. The relationship between birth weight and health is strongest during infancy, after which it weakens throughout childhood and adolescence. In adulthood, a stronger relationship again appears, suggesting a U-shaped relationship over the examined part of the life course. During childhood and adolescence, birth weight influences all examined disease types with the exception of cancers, with nontrivial effect sizes in relative terms. During adulthood, morbidity due to mental diseases dominates, primarily through conditions with early-age origins. Consequently, we provide new evidence that birth weight matters for both short- and long-term health outcomes and that it is of a dynamic nature in terms of its magnitude and which disease types are affected. Lastly, our results remain robust to a range of sensitivity analyses, including nonlinear specifications of birth weight, and to estimations based on a sample of same-sex twin pairs, allowing us to further reduce the influence of genes.

We examine birth order differences in health of newborns and follow the children throughout childhood using high-quality administrative data on individuals born in Denmark between 1981 and 2010. Family fixed effects models show a positive and robust effect of birth order on health at birth; firstborn children are less healthy at birth. During earlier pregnancies, women are more likely to smoke, receive more prenatal care, and are more likely to suffer a medical pregnancy complication, suggesting worse maternal health. We further show that the health disadvantage of firstborns persists in the first years of life, disappears by age seven, and becomes a health advantage in adolescence. In contrast, later-born children are throughout childhood more likely to suffer an injury. The results on health in adolescence are consistent with previous evidence of a firstborn advantage in education and with the hypothesis that postnatal investments differ between first- and later-born children.

This paper makes two contributions to the literature on the effects of wealth on health. First, it deals with reverse causality and omitted variable bias by exploiting exogenous variation in inherited wealth generated by the repeal of the Swedish inheritance tax. Second, it analyzes responses in health outcomes through the use of administrative registers. The results show that increased wealth has limited short to medium run impacts on objective adult health. This is in line with what has previously been reported in the literature. [ABSTRACT FROM AUTHOR]

Health and education are known to be highly correlated, but the mechanisms behind the relationship are not well understood. In particular, there is sparse evidence on whether adolescent health may influence educational attainment. Using a large registry dataset of twins, including comprehensive information on health status at the age of 18 and later educational attainment, we investigate whether health predicts final education within monozygotic (identical) twin pairs. We find no evidence of this and conclude that health in adolescence may not have an influence on the level of schooling. Instead, raw correlations between adolescent health and schooling appear to be driven by genes and twin-pair-specific environmental factors. [ABSTRACT FROM AUTHOR]

Cesarean sections are rising all over the world and may, in some countries, soon become the most common delivery mode. A growing body of medical literature documents a robust fact: women undergoing cesarean sections end up having less children. Unlike most of the medical literature, which assumes that this association is mostly working through a physiological channel, we investigate a possible channel linking c-section and subsequent fertility through differences in maternal behavior after a c-section. Using several national and cross-national demographic data sources, we find evidence that maternal choice is playing an important role in shaping the negative association between cesarean section and subsequent fertility. In particular, we show that women are more likely to engage in active contraception after a cesarean delivery and conclude that intentional avoidance of subsequent pregnancies after a c-section seems to be responsible for part of the negative association between c-sections and subsequent fertility.

We study labor-market discrimination of individuals with 'specific' characteristics in Italy. We conduct a field experiment in two Italian cities: Rome and Milan, by sending 'fake' CVs to real ads. We find that there is a strong penalty for homosexuals, i.e., about 30 % less chance to be called back compared to a heterosexual male and even more so if they are highly skilled. On the other hand, we find no penalty for homosexual females. We also find a beauty premium for females only but this premium is much lower when the 'pretty' woman is skilled. [ABSTRACT FROM AUTHOR]

This paper exploits the discrete jump in alcohol consumption at the minimum legal drinking age (MLDA) in the USA and uses a regression discontinuity design to investigate the relationship between drinking and risky sexual behaviors among young adults. Using confidential data from the National Longitudinal Survey of Youth (1997 Cohort), we document that young adults tend to drink up to 2.1 days more once they are granted legal access to alcohol at age 21. Although the discrete jump in alcohol consumption at the MLDA is associated with an increase in the probability of having sex by up to 7.8 percentage points, it does not have a significant impact on the probability of engaging in risky sexual behaviors among young adults. We also document that the effect of the MLDA on the probability of using several different birth control methods is not significant for those who had sex in the past 4 weeks. These results are robust under alternative specifications and imply that although the MLDA law is quite effective in reducing alcohol consumption among young adults, spillover effects of this law on risky sexual behaviors are relatively limited.

The aim of this study is to assess the effects of economic conditions in early life on cause-specific mortality during adulthood. The analyses are performed on a unique historical sample of 14,520 Dutch individuals born in 1880-1918, who are followed throughout life. The economic conditions in early life are characterized using cyclical variations in annual real per capital gross domestic product during pregnancy and the first year of life. Exposure to recessions in early life appears to significantly increase cancer mortality risks of older males and females. It also significantly increases other mortality risks especially for older females. The residual life expectancies are up to about 8 and 6 % lower for male and female cancer mortality, respectively, and up to about 5 % lower for female cardiovascular mortality. Our analyses show that cardiovascular and cancer mortality risks are related and that not taking this association into account leads to biased inference. [ABSTRACT FROM AUTHOR]

In this paper, we show a simple correction for the aggregation effect when testing the relationship between income inequality and life expectancy using aggregated data. While there is evidence for a negative correlation between income inequality and a population's average life expectancy, it is not clear whether this is due to an aggregation effect based on a non-linear relationship between income and life expectancy or to income inequality being a health hazard in itself. The proposed correction method is general and independent of measures of income inequality, functional form assumptions of the health production function, and assumptions on the income distribution. We apply it to data from the Human Development Report and find that the relationship between income inequality and life expectancy can be explained entirely by the aggregation effect. Hence, there is no evidence that income inequality itself is a health hazard. [ABSTRACT FROM AUTHOR]

The Family Health Program (Programa Saúde da Família) is an initiative of the Brazilian Ministry of Health designed to deliver free primary health care services within communities and households. The program was implemented by municipalities in different periods of time, creating variation in its availability among siblings of different ages. The empirical approach uses this variation to estimate the effect of the program on children's health in Brazil, in an attempt to control for family and municipality unobserved factors possibly related to the program's adoption. The results indicate that children for whom the Family Health Program was available in their municipalities during the prenatal period are healthier than children for whom the program was not available during the same period of their lives.

This paper investigates the causal effect of improvements in health on economic development using a long panel of European countries. Identification is based on the particular timing of the introduction of public health care systems in different countries, which is the random outcome of a political process. We document that the introduction of public health care systems had a significant immediate effect on health dynamics proxied by infant mortality and crude death rates. The findings suggest that health improvements had a positive effect on growth in income per capita and aggregate income. [ABSTRACT FROM AUTHOR]

Much uncertainty surrounds the length of human life. The standard deviation in adult life span is about 15 years in the USA, and theory and evidence suggest that it is costly. I calibrate a utility-theoretic model that shows that 1 year in standard deviation is worth about half a life year. Differences in variance exacerbate health inequalities between and among rich and poor countries. Accounting for the cost of life-span variance appears to amplify recently discovered patterns of convergence in world average human well-being because the component of variance due to infant mortality has exhibited even more convergence than life expectancy.

This study uses data from the National Institute of Child Health and Human Development Study on Early Child Care to examine the effects of maternal employment on maternal mental and overall health, self-reported parenting stress, and parenting quality. These outcomes are measured when children are 6 months old. Among mothers of 6-month-old infants, maternal work hours are positively associated with depressive symptoms and parenting stress and negatively associated with self-rated overall health. However, maternal employment is not associated with quality of parenting at 6 months, based on trained assessors' observations of maternal sensitivity. [ABSTRACT FROM AUTHOR]

In this paper, we examine the impact of family size on maternal health outcomes by exploiting the tremendous change in family size under the One-Child policy in China. Using data from the China Health and Nutrition Survey 1993-2006, we find that mothers with fewer children have a higher calorie intake and a lower probability of being underweight and having low blood pressure; meanwhile, they have a higher probability of being overweight. This would occur if a smaller family size increases the food consumption of mothers, leading underweight women to attain a normal weight and normal weight women becoming overweight. Robust tests are performed to provide evidence on the hypothesis that the tradeoff between children's quantity and mother's 'quality' is through a budget constraint mechanism, that is, having more children decreases the resource allocated to mothers and affects their health outcomes.

We use data on young women from the National Longitudinal Study of Adolescent Health to explore the relationship between number of sex partners and educational attainment. Using the average physical development of male schoolmates to generate plausibly exogenous variation in number of sex partners, instrumental variables estimates suggest that number of sex partners is negatively related to educational attainment. This result is consistent with the argument that romantic involvements are time consuming and can impose substantial emotional costs on young women. [ABSTRACT FROM AUTHOR]

We evaluate the impact of the HIV/AIDS epidemic on the reproductive behaviour for all women in Malawi, HIV-negative and HIV-positive alike, allowing for heterogeneous response depending on age and prior number of births. HIV/AIDS increases the probability that a young woman gives birth to her first child, while it decreases the probability to give birth of older women and of women who have already given birth. The resulting change in the distribution of fertility across age groups is likely to be more demographically and economically important than changes in the total number of children a woman gives birth to.

About 30% of Americans are obese, which is roughly a 100% increase from 25 years ago. This study examines the effects of changes in the racial/ethnic composition and age distribution on the prevalence of obesity, identifies the portion of the increase in obesity caused by these changes, and projects the effects of future racial/ethnic and age changes on obesity using National Health and Nutrition Examination Survey data. Results indicate that racial/ethnic composition changes and age distribution changes have accounted for about 10% of the increase in obesity over the last 25 years. However, future racial/ethnic and age changes are not projected to increase obesity substantially. [ABSTRACT FROM AUTHOR]

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.).

This paper investigates the outcome of ageing on taxes and hospitalisation of the elderly using panel data on 23 Swedish county councils 1980–1999. We test two hypotheses; whether a larger share of elderly has no negative effect on bed days per elderly person and no positive effect on tax rates. We reject the first hypothesis but fail to reject the second hypothesis. Further we cannot reject the hypothesis of a unitary elasticity of the share of elderly on bed days per elderly person. These results imply that the old bear the entire cost of adjustment when the population grows older. [ABSTRACT FROM AUTHOR]

Recent research concerning the incidence of reported work-limiting disabilities in the married population indicates a degree of interdependence between spouses' disabilities. This pattern is consistent with several hypotheses. Spouses tend to share many lifestyle traits that might lead to common health outcomes. Alternatively, their joint reports might reflect a shared preference for income benefits or workplace accommodations available to disabled individuals. Another possibility is that disabled individuals tend to be matched in the process of marital formation. This paper investigates the latter hypothesis. Taking advantage of a unique data set from the Swedish population, we select a sample of recently married couples and trace them back in time to their single years. Our analysis indicates nonrandom matching on the basis of disability status. After controlling for observed traits such as age and education, we find a residual correlation between future spouses that is positive and strongly significant. The magnitude of the correlation is within the range of residual correlations obtained from other studies that address marital matching in the contexts of education and earnings.
