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 (^{circ })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.

In this paper, we examine how religious mandates of the holy month of Ramadan affect the gendered distribution of time use within Muslim households in India. Using rich data on time use from a nationally representative time use survey and employing a difference-in-differences methodology, we test if Ramadan accentuates gender differences in time use. We find that, contrary to popular belief, Ramadan moderates the gender disparities in intra-household time use for Muslim households. The moderating influence is stronger in districts with a higher Muslim proportion. We find that the reduction in gender differences is due to declines in gender-specific time use in employment, learning activities, domestic work and self-care. Reduction in domestic work time for women, especially food preparation time, is more pronounced in districts with a high Muslim proportion, suggesting ‘communalisation of domestic work’ due to Ramadan.

This paper investigates the impact of social media interest and sentiment surrounding the 2020 National Basketball Association’s involvement with the Black Lives Matter movement on the television audience in the United States. Twitter (now known as X) serves as the chosen social media platform, and we determine the sentiment expressed in tweets (messages posted on Twitter) using the XLM-RoBERTa deep language model. Our primary findings indicate that the quantity of users’ posts does not significantly influence TV viewership; instead, the tone of the messages plays a crucial role. Positive messages supporting the NBA’s engagement correlate with an increase in the number of viewers, while those expressing opposition do not. We argue that this asymmetry may stem from a positive elasticity among casual (non-habitual) NBA viewers concerning positive sentiments toward NBA involvement. These viewers are likely to align with the NBA’s stances on civil rights and BLM. In contrast, the core NBA fan base exhibits inelastic demand and is unlikely to cease watching NBA games. A comprehensive set of robustness checks reinforces the validity of our key conclusions.

This paper studies the labor market impacts of the Venezuelan immigration in Colombia. Exploiting spatial variation in exposure, I find a negative effect on native wages driven by the informal sector (where immigrants are concentrated) and a reduction in native employment in the formal sector (where the minimum wage binds for many workers). To explain this, I build a model in which a firm substitutes formal for informal labor in response to lower informal wages. Consistent with the model’s predictions, I document that the decrease in formal employment is driven by small firms that use both labor types in production and by workers earning the minimum wage.

This paper examines the role of individuals’ emotions in determining their concerns about international migration. For the empirical analysis, we exploit little-explored information in the German Socio-Economic Panel (SOEP) data on individuals’ negative emotions, e.g., anger, fear, and sadness. We find that the frequency of experiencing negative emotions is positively associated with immigration concerns. Moreover, we show that the relationship varies across employment status, birth cohort, and social media usage. Our analysis also underscores the real-life consequence of emotions by demonstrating their positive association with support for far-right political parties among males, but not among females. Finally, we exploit the exogenous variation in negative emotions induced by the death of a parent to infer causality. Fixed effects regressions with instrumental variables exhibit a positive impact of negative emotions on immigration concerns among females, but no significant effects are found among males. Further investigation into channels driving these gender differences in results underscores gender differences in roles played by other concerns that often carry over to determine individuals’ immigration concerns, e.g., concerns about international terrorism.

We examine how the gender of business owners is related to the wages paid to female relative to male employees working in their firms. Using Finnish register data and employing firm fixed effects, we find that the gender pay gap is—starting from a gender pay gap of 11 to 12%—two to three percentage points lower for hourly wages in female-owned firms than in male-owned firms. Results are robust to how the wage is measured, as well as to various further robustness checks. More importantly, we find substantial differences between industries. While, for instance, in the manufacturing sector, the gender of the owner plays no role in the gender pay gap, in several service sector industries, like ICT or business services, no or a negligible gender pay gap can be found, but only when firms are led by female business owners. Businesses with male ownership maintain a gender pay gap of around 10% also in the latter industries. With increasing firm size, the influence of the gender of the owner, however, fades. In large firms, it seems that others—firm managers—determine wages and no differences in the pay gap are observed between male- and female-owned firms.

Previous literature has established that lesbian, gay, and bisexual (LGB) people are at least as likely to be poor as heterosexual people, standing in contrast to myths of “gay affluence.” These findings have used datasets limited by either sample size or using partnership status to infer sexual orientation. Using U.S. data from the Household Pulse Survey, which allows us to identify large samples of individuals who self-identify as lesbian, gay, or bisexual, we find that bisexuals have lower incomes and are more likely to experience poverty, and bisexual individuals, gay men, and lesbian women are more likely to report financial hardship. Additionally, we find that LGB people utilize government assistance at higher rates than heterosexual people, even when allowing for selection into poverty status. We propose several explanations for these differentials, drawing on the program non-participation literature, and suggest that social network effects, lessened stigma, and increased reliance on public programs may explain these differences. Finally, we examine receipt of the enhanced child tax credit and find evidence that gay men and lesbian women with children were less likely to receive it than heterosexual men and women with children.

Post-marital residence norms govern where a married couple resides after marriage: with the husband’s family, the wife’s family, or independently. We study whether these arrangements affect female autonomy and domestic violence outcomes in four Southeast Asian countries—Indonesia, Philippines, Cambodia, and Myanmar—where a sizable proportion of the population practices each type of marital residence. Compared to independently residing families within the same province-country, married women residing with the husband’s family have worse autonomy outcomes, whereas those residing with members of their own natal families fare substantially better. This aligns well with an anthropological understanding of how gendered patterns of influence in a social system might potentially interact with female empowerment. On the other hand, we observe that married women in both types of non-independent households suffer from less frequent domestic abuse compared to women residing independently, likely due to a deterrence effect from the presence of other family members.

Much less is known about the impacts of the COVID-19 pandemic on the provision of early childhood preschool services relative to research on school closures. We conducted surveys of more than 5000 early childhood service providers and leverage temporal and spatial variation in India’s intensity of lockdowns to quantify disruptions to preschool services under the world’s largest early childhood development program between areas with different strictness of lockdown measures. We document a 23 percentage point reduction in the provision of preschool services in red zone lockdown areas (strictest measures) relative to green zone lockdown areas (least strict measures). We find that pre-COVID measures of high worker locus of control and public service motivation offset the reduction in differential preschool service provision by 27–37%.

This paper presents an analysis of the effects of public old-age support on individuals’ fertility decisions and on the long-term equilibrium in an overlapping generation economy with strategic bequest motives. Parents must pay their adult children at least the reservation wage to receive informal old-age support from them (individual rationality constraint). Formal old-age support is financed through wage taxes on children. The increased present value of formal old-age support tends to increase old-age utility, thereby decreasing the family support demand and decreasing savings for the old age. The increased wage tax reduces the opportunity cost of child-rearing time, thereby increasing the fertility rate. The effects of increased formal old-age support on per-worker capital and labor are indeterminate, as is the effect on the long-term lifetime utility of individuals. A strategic bequest motive might engender a higher fertility rate than that of the social optimum.
