Author Abstract: This chapter reviews the empirical literature on the impacts of temperature and climate change on human pregnancies. The focus is on the quasi-experimental studies that use panel data, apply a fixed effect approach, and exploit the random year-to-year fluctuation in temperature. The insights that emerge from the review highlight that exposure to heat in the pre-conception period has detrimental impacts on fertility. In addition, heat during pregnancy increases pregnancy losses, leads to a reduction in gestational length, and lowers birth weight. Despite the growing empirical evidence on the subject, understanding the relationship between temperature and pregnancy-related outcomes is far from perfect. Importantly, the potential impacts of climate change are rarely quantified. The chapter outlines directions for future research.

Reconciling the opposing economic effects of works councils across databases – Download PDF
by Mohrenweiser, Jens

GLO Fellow Jens Mohrenweiser

Author Abstract: Recent studies on the economic effects of works councils in Germany using the European Company Survey estimate a significant negative effect of works councils on establishment productivity and profitability. These results are in stark contrast to studies using the IAB Establishment Panel estimating a significant positive effect of works councils on establishment productivity and profitability. This article scrutinises these empirical approaches. While sample selection and control variables have a substantial impact on the magnitude of marginal effects, the definition of the dependent variable as an objective or subjective measure causes the opposing signs. Beyond that, similar measures in both datasets lead to comparable marginal effects highlighting the relevance of the definition of the dependent variable for inferences and interpretation of studies about the effectiveness of industrial relations institutions and raising questions about the validity of the performance measures.

The Long-Term Effect of FIFA World Cup on Gender Gap in Education and Employment: Evidence from Vietnam – Download PDF

by Nguyen, Cuong Viet & Tran, Anh Ngoc

GLO Fellow Cuong Nguyen

Author Abstract: The FIFA Soccer World Cups often happen within one month just before the national entrance exam to universities and colleges in Vietnam. Watching soccer matches can distract male students from their studies and reduce their probability to pass the exam. We find that Vietnamese men who had the university entrance exam during the FIFA Soccer World Cups tend to have a lower proportion of having a bachelor’s degree. Exposure to World Cups also reduces the probability of having a formal job, a high-skilled job and management position for men. Using the exposure to World Cups as a natural shock for tertiary education, we find a large and positive effect of tertiary education on employment. It confirms the important role of education in reducing gender gap in employment.

Trends in subjective income poverty rates in the European Union – Download PDF
by Želinský, Tomáš & Mysíková, Martina & Garner, Thesia I.

GLO Fellow Tomas Zelinsky

Author Abstract: When developing anti-poverty policies, policy makers need accurate data on the prevalence of poverty. In this paper, we focus on subjective poverty, a concept which has been largely neglected in literature, yet remains a conceptually appealing way to define poverty. The primary goal of this study is to re-examine the concept of subjective poverty measurement and to estimate trends in subjective poverty rates in the European Union. Our estimations are based on a minimum income question using data from a representative survey, EU-SILC, and we find a decreasing trend in subjective poverty in 16 of 28 countries. Conversely, the official relative income poverty indicator exhibits increasing trends in eleven countries, with decreasing trends in only four countries. We believe that these trends may reflect changes in societies which have not been previously captured, and our results thus enrich the existing data on general poverty trends in the EU.

Social Mobility and Political Regimes: Intergenerational Mobility in Hungary, 1949-2017 – Download PDF
by Bukowski, Paweł & Clark, Gregory & Gáspár, Attila & Pető, Rita

GLO Fellow Rita Pető

Author Abstract: This paper measures social mobility rates in Hungary 1949-2017, for upper class and underclass families, using surnames to measure social status. In these years there were two very different social regimes. The first was the Hungarian People’s Republic, 1949-1989, a Communist regime with an avowed aim of favouring the working class. Then the modern liberal democracy, 1989-2020, a free-market economy. We find five surprising things. First, social mobility rates were low for both upper- and lower-class families 1949- 2017, with an underlying intergenerational status correlation of 0.6-0.8. Second, social mobility rates under communism were the same as in the subsequent capitalist regime. Third, the Romani minority throughout both periods showed even lower social mobility rates. Fourth, the descendants of the noble class in Hungary in the eighteenth century were still significantly privileged in 1949 and later. And fifth, while social mobility rates did not change measurably during the transition, the composition of the political elite changed fast and sharply.

Poor vs Non-Poor Households in Uruguay: Welfare Differences from Food Price Changes – Download PDF
by Echeverría, Lucía & Molina, José Alberto

GLO Fellow José Alberto Molina

Author Abstract: Evidence suggests that household responses to price and income changes are significantly sensitive across income levels and rural-urban location. In this paper, we focus on poor households vs. non-poor households using two definitions of poverty, objective and subjective. We evaluate the differential responses of poor households vs. non-poor households to changes in food expenditures and prices and simulate the welfare losses from food price changes across poverty definitions. We use the QUAIDS model to estimate food elasticities with data from the National Expenditure and Household Income Survey, 2016-2017, from Uruguay. Expenditure elasticities at the food level reveal that bread and dairy products are a necessity-food category, regardless of the poverty status and across poverty definitions, while beverages are a luxury good. The demand sensitivity for the rest of the food categories differs by poverty status and poverty definitions. Uncompensated own-price elasticities indicate that when poverty is defined objectively, then changes in demand due to changes in price are greater for poor households (except for meat products). However, poor households, under the subjective definition, are more sensitive than non-poor households only to changes in beverage prices. Additionally, changes in household economic welfare due to price increases vary according to poverty status. On average, the percentage of total income needed to avoid a loss in economic welfare of poor households, defined by the objective method, is double that required by the non-poor households, for all price changes. However, differences are much smaller when using the subjective approach to measure poverty.

Something in the Pipe: Flint Water Crisis and Health at Birth – Download PDF
by Wang, Rui & Chen, Xi & Li, Xun

GLO Fellow Xi Chen

Author Abstract: In 2014, the city of Flint, MI in the U.S. changed its public water source, resulting in severe water contamination and a public health crisis. Using the Flint Water Crisis as a natural experiment, we estimate the effect of in utero exposure to polluted water on health at birth. Matching vital statistics birth records with various sources of data, we use a Synthetic Control Method (SCM) to identify the causal impact of water pollution on key birth outcomes. Our results suggest that the crisis modestly increased the rate of low birth weight (LBW) by 1.8 percentage points (or 15.5 percent) but had little effect on the length of gestation or rate of prematurity. However, these effects are larger among children born to black mothers, as indicated by an increase in the rate of LBW by 2.5 percentage points (or 19 percent). Children born to white mothers exhibit, on average, a 30.1-gram decrease in birth weight. We find little evidence that the male-to-female sex ratio declines in the overall population, suggesting that the inutero scarring effect of the Flint Water Crisis may dominate the channel of mortality selection. However, we observe a slight decline in the sex ratio among children born to black mothers. Finally, we find no notable change in the fertility rates of either black women or white women in Flint. These results are robust to a rich set of placebo and falsification tests. Our findings highlight the importance and urgency of upgrading U.S. aging, lead-laced water systems in promoting racial and ethnic health equity.

Author Abstract: This study explores the differential impact of weather on time allocation to physical activity and sleep by children and their parents. We use nationally representative data with time use indicators objectively measured on multiple occasions for more than 1,100 child-parent pairs, coupled with daily meteorological data. Employing an individual fixed effects regression model to estimate the causal impact of weather, we find that unfavourable weather conditions, as measured by cold or hot temperatures or rain, cause children to reduce physical activity time and increase sedentary time. However, such weather conditions have little impact on children’s sleep time or the time allocation of their parents. We also find substantial differential weather impact, especially on children’s time allocation, by weekdays/weekends and parental employment status, suggesting that these factors may contribute to explaining the differential weather impact that we observed. Our results additionally provide evidence of adaptation, as temperature appears to have a more pronounced impact on time allocation in colder months and colder regions. The results suggest that extreme weather conditions, including those associated with climate change, could make children vulnerable to reduced physical activity.
