This paper evaluates the effect of Paid Family Leave (PFL) on breastfeeding and immunizations- two critical parental investments in infant health - which we identify using California's 2004 PFL policy that ensured mothers up to six weeks of leave at a 55% wage replacement rate. We employ difference-in-difference and difference-in-difference-in-differences models for a large, representative sample of children (N=314,532) born between 2000 and 2013 drawn from the restricted-use versions of the 2003-2014National Immunization Surveys. Our most conservative estimates indicate that access to PFL is associated with at least a 15% increase in breastfeeding exclusively for at least six months. We find substantially large effects for disadvantaged mothers, adding to the existing evidence that access to state-sanctioned paid family leave might benefit children overall and disadvantaged children in particular.

We evaluate the direct and spillover causal effects of a Hepatitis B (HB) vaccination campaign in French schools on the vaccination adherence of the targeted pupils. Using a regression discontinuity design, we show that this campaign created an exogenous shock on vaccination behavior, increasing the HB vaccination rate for children aged 11 and above. At the same time, we show a drop in the measles, mumps, and rubella (MMR) vaccination rate of the targeted pupils and an increase in the parental belief that measles is a benign disease. We interpret these results as a salience effect: the focus on HB vaccination leads to a decrease in the belief that other vaccines are as important. The effect on MMR vaccination was relatively unexpected and may imply a negative externality. Measles is an extremely contagious disease. If the vaccination rate falls, the disease will spread further, raising the question of the net effect of the HB vaccination campaign on the well-being of the population.

Obesity rates and soda consumption are increasing at a worrisome pace in developing countries. In particular, soda companies seem to be targeting areas with poor access to clean water. This paper exploits a natural experiment in Peru and finds evidence that changes in the price of soda generate important effects in terms of obesity among individuals without piped water at home. These significant effects are driven by a combination of a large effect in the consumption of soda and an effect close to zero in the consumption of potential substitutes high in calories. This paper also provides some evidence that a reduction in price of soda reduces diarrhea prevalence, suggesting that some individuals substitute away contaminated water. This evidence suggests that soda taxes might be particularly beneficial among this population in terms of the prevention of obesity and possibly related diseases such as diabetes and cardiovascular diseases. The potential trade-off between obesity and diarrhea needs to be investigated in greater depth.

This paper analyzes gender differences regarding the effect of the COVID-19 pandemic on the likelihood of job loss, differentiating between employment transitions towards unemployment, inactivity and furlough schemes, and the role that teleworking may have had as a protector of job loss in Spain. Based on more than 1,800 types of jobs defined by occupation and economic activity combinations, we propose an Evidence-Based Teleworking Index that considers the intensity of telework use in a given type of job, but also reflects the actual ability of firms to adapt to telework. Using multinomial probit models with sample selection, we found that more women than men suffered job loss during the pandemic. The findings also confirm that the ability to telework has acted as a potential cushion against employment losses, but the effect has been mainly driven by males. The shielding effects of telework have been especially relevant in reducing transitions from employment to furlough schemes, while the power of telework to protect against inactivity and unemployment seems to be much more modest, even during the pandemic.

This analysis examines the effect of COVID-19 on public mental health in Switzerland. Following an event-study framework, we compare helpline call volume and duration before and after the outbreak of the first and second wave. The use of administrative phone-level data allows us to i) decompose the total effects into an intensive and extensive margin and ii) calculate a measure of unmet need. For the first wave, our results show that callers with a history of helpline contacts increase calls substantially. We also identify capacity constraints leading to unmet need for psychological counseling. Finally, we find no effects in the second wave, which might be explained by a number of factors including the absence of a lockdown and less restrictive social distancing measures.

To assess the impact of taxation on the consumption of sugar-sweetened beverages (SSBs) most economic studies using household data consider the average consumer. Individual consumption is, however, very heterogeneous. In this paper, we propose a three-step methodology to evaluate the impact of SSB taxation on individual consumption. First, we use a disaggregation method to recover individual consumption from observed household consumption. Second, we estimate the demand for different categories of households. Finally, we simulate the impact of a tax policy on individual consumption. We find a high level of heterogeneity in consumption. Adults, both men and women, consume a greater quantity of SSBs than children. More importantly, for any given age category, the average consumption of SSBs increases with body mass index (BMI). Among heavy consumers of SSBs, obese and overweight people are over-represented. In France, a €0.20/l tax on SSBs might decrease sugar intake by more than 2 kg per year on average and by more than 5 kg, roughly 3 teaspoons/day, for 5% of the adult population. Moreover, overweight and obese men and women, who correspond to 41% of the adult population, represent 56% of the last five percentiles of the distribution of the variation in sugar intake. This is a key result because the objective of taxation is to decrease the consumption of individuals who are more at risk, that is those who are overweight and obese. We also show that classical method of the assessment of tax policies based on per-capita consumption underestimate the effect of the tax for obese adults by 9%. Finally, we estimate that a €0.20/l tax on SSBs might avoid about 640 deaths (about 1.6% of the considered diseases) as a consequence of the decrease in SSB consumption.

Obesity has a profound effect on the working careers of Americans. Prior studies pertaining to workers in other countries report that obese women experienced longer spells of unemployment than normal weight peers. However, the effect of obesity on unemployment duration has not been studied for American workers. To address this gap in the literature, we report estimates of the effects of overweight and obesity from a proportional hazards model of unemployment duration that controls for unobserved individual characteristics. Using a data sample of young workers drawn from the National Longitudinal Survey of Youth (1997), our findings indicate that, on average, overweight and obese job seekers experienced significantly longer spells of unemployment. The effects differed by race, sex, and ethnicity: Overweight and obese White and Black women experienced significantly longer spells than White women with normal body mass index (BMI) levels. Although overweight White and Black men had longer unemployment spells compared to White men with normal BMI levels, the magnitudes were smaller than those for White and Black women. In contrast, overweight Hispanic women had shorter duration of unemployment spells compared to White women with normal BMI levels.

Poor health at birth can have long-term consequences for children's development. This paper analyses an important factor associated with health at birth: the time of year that the baby is born, and hence seasonal risks they were exposed to in utero. There are multiple potential explanations for seasonality in newborns' health. Most previous research has examined these in isolation. We therefore do not know which explanations are most important - and hence which policy interventions would most effectively reduce the resulting early-life inequalities. In this paper, I use administrative data to estimate and compare the magnitudes of several seasonal risks, seeking to identify the most important drivers of seasonality in the Northern Territory of Australia, a large territory spanning tropical and arid climates and where newborn health varies dramatically with the seasons. I find that the most important explanations are heat exposure and disease prevalence. Seasonality in food prices and road accessibility have smaller effects on some outcomes. Seasonal fertility patterns, rainfall and humidity do not have statistically significant effects. I conclude that interventions that protect pregnant women from seasonal disease and heat exposure would likely improve newborn health in the Northern Territory, with potential long-term benefits for child development. It is likely that similar impacts would apply in other locations with tropical and arid climates, and that, without action, climate change will accentuate these risks.

This study analyzes the weather-related health damage of present and future extreme temperatures in Argentina. Focusing on mortality, short-term impacts of temperature are obtained by regressing monthly mortality rates on inter-annual monthly weather variability. For this purpose, a countrywide panel dataset at the municipal level was constructed from the universe of deaths between 2010 and 2019, and daily meteorological records from the ERA5 weather dataset. Then, NASA Earth Exchange Global Daily Downscaled Projections (NEX-GDDP) are used to project future mortality by 2085 under two climate scenarios. Finally, present and future mortality-related economic damages are assessed using the Value of a Statistical Life. The results show that one additional day of extreme temperatures increase all-cause mortality rates relative to mild weather and that the impact of hotter-than-average temperatures is greater in magnitude than that of colder ones. Substantial heterogeneity exists between causes of death and age groups, with older people facing greater risks, while the results for gender are inconclusive. All days of extreme cold in a year generate damage equivalent to 0.64% of GDP, while heat damage is 0.11% of GDP. The total damage by extreme temperatures adds up to 0.75% of the 2019 GDP. When future temperatures are valued, the total damage increases by an additional 1.45% under scenario RCP8.5 because the lower mortality occurring on cold days only partially offsets the increase in the number of hot days. On the contrary, if temperature changes were to be mild (i.e., under scenario RCP4.5), overall mortality would be lower at the national level and the corresponding damages would decrease by 0.02%.

We investigate the effect of early exposure to malnutrition on the cognitive abilities of the offspring of survivors in the context of a natural experiment; i.e., the Great Chinese Famine (GCF) of 1959-61. We employ a novel dataset - the China Family Panel Studies (CFPS) - to do so. The paper finds that the cognitive abilities of children whose fathers were born in rural areas during the famine years (1959-1961) were impaired by exposure to the GCF and the negative effect was greater for girls than boys, whereas children whose mothers were born in rural areas during the famine years were not affected. The uncovered gender-specific effect is almost entirely attributable to son preference exhibited in families with male famine survivors.
