Why does the health of Mexican immigrants deteriorate? New evidence from linked birth records

This study uses a unique dataset linking the birth records of two generations of children born in California and Florida (1970-2009) to analyze the mechanisms behind the generational decline observed in birth outcomes of children of Mexican origin. Calibrating a simple model of intergenerational transmission of birth weight, I show that modest positive selection on health at the time of migration can account for the initial advantage in birth outcomes of second-generation Mexicans. Moreover, accounting for the socioeconomic differences between second-generation Mexicans and white natives and the observed intergenerational correlation in birth weight, the model predicts a greater deterioration than that observed in the data. Using a subset of siblings and holding constant grandmother quasi-fixed effects, I show that the persistence of healthier behaviors among second-generation Mexican mothers can explain more than half of the difference between the model prediction and the observed birth outcomes of third-generation Mexicans.

Circadian Rhythms, Sleep and Cognitive Skills: Evidence from an Unsleeping Giant

This study analyzes the effects of sleep duration on cognitive skills and depression symptoms of older workers in urban China. Cognitive skills and mental health have been associated with sleep duration and are known to be strongly related to economic behavior and performance. However, causal evidence is lacking, and little is known about sleep deprivation in developing countries. We exploit the relationship between circadian rhythms and bedtime to identify the effects of sleep using sunset time as an instrument. Using the Chinese Health and Retirement Longitudinal Study, we show that a later sunset time significantly reduces sleep duration and that sleep duration increases cognitive skills and eases depression symptoms of workers aged 45 years and older. The results are driven by employed individuals living in urban areas, who are more likely to be constrained by rigid work schedules. We find no evidence of significant effects on the self-employed, non-employed, or farmers.

Assimilation and Health: Evidence From Linked Birth Records of Second- and Third-Generation Hispanics

This study explores the effects of assimilation on the health of Hispanics in the United States, using ethnic intermarriage as a metric of acculturation. I exploit a unique data set of linked confidential use birth records in California and Florida from 1970–2009. The confidential data allow me to link mothers giving birth in 1989–2009 to their own birth certificate records in 1970–1985 and to identify second-generation siblings. Thus, I can analyze the relationship between the parental exogamy of second-generation Hispanic women and the birth outcomes of their offspring controlling for grandmother fixed effects as well as indicators for second generation’s birth weight. Despite their higher socioeconomic status, third-generation children of second-generation intermarried Hispanic women are more likely to have poor health at birth, even after I account for second-generation health at birth and employ only within-family variations in the extent of assimilation. I find that a second-generation Hispanic woman married to a non-Hispanic man is 9 % more likely to have a child with low birth weight relative to a second-generation woman married to another Hispanic. These results largely reflect the higher incidence of risky behaviors (e.g., smoking during pregnancy) among intermarried Hispanic women.

The Hispanic health paradox: New evidence from longitudinal data on second and third-generation birth outcomes

This study examines the birth weight of second and third-generation Hispanics born in California and Florida, two of the major immigrant destination states in the US. I exploit a unique dataset of linked birth records for two generations of children born in California and Florida (1970–2009) and linear probability models to investigate the generational decline in the birth outcomes of Hispanics in the US. The data allow using an extensive set of socio-demographic controls and breaking down the results by country of origin. Second-generation children of Mexican and Cuban origin have better birth outcomes than children of US-born white women. Children of Puerto Rican origin have instead worse birth outcomes. The advantage observed among second-generation Hispanics erodes substantially in the third generation but third-generation Mexicans retain some of it.

Weight gains from trade in foods: Evidence from Mexico

In this paper, we investigate the effects of trade in foods on obesity in Mexico. To do so, we match data on Mexican food imports from the U.S. with anthropometric and food expenditure data. Our findings suggest that exposure to food imports from the U.S. explains about ten percent of the rise in obesity prevalence among Mexican women between 1988 and 2012. Pro-obesity effects are driven by areas more exposed to unhealthy food imports. We also find evidence in favour of a price mechanism. By linking trade flows to obesity, the paper sheds light on an important channel through which globalisation may affect health.

Migration, Health, and Well-being: Models and Methods

Abstract In the public debate, immigration is often viewed as a threat to the access and the quality of health care services. The health needs of immigrants and refugees pose new challenges to health care systems. This chapter reviews the recent economic literature on immigration and health. We discuss the main methods used to study the health immigrant trajectories and the effects of immigration on demand and supply of health care in both destination and sending countries.

Has the growth in “fast casual” Mexican restaurants impacted weight gain?

&NA; The United States is witnessing a boom in fast casual restaurants owing to the recent growth of ethnic restaurants throughout the country. This study examines the effects of proximity to a Mexican restaurant—the dominant type of ethnic fast casual restaurant—on maternal and child health. I match data on the complete residential addresses of all mothers who gave birth in the Miami metropolitan area between 1990 and 2009 to a time series of all establishments (restaurants and stores) selling food and drink. This unique data set allows me to use mother fixed effects and to exploit the variation over time of the food environment to identify the effects on maternal weight gain and childbirth outcomes. The results show that living in proximity to a Mexican restaurant is associated with an 8% lower likelihood of excessive weight gain among US‐born mothers. These effects are concentrated in low‐income neighborhoods and among members of disadvantaged groups (e.g., low‐skilled, young, and African‐American individuals). However, the results show no protective effect for foreign‐born mothers. Lastly, there is no evidence of significant effects on other maternal outcomes or on various child health metrics at birth.
