Heterogeneous effects of emigration on labor market activity and investment decisions in Punjab, Pakistan.

We investigate the impacts of emigration on the labor market and investment decisions of migrant-sending households in Pakistan by constructing a large individual-level dataset, using several rounds of the Multiple Indicator Cluster Survey conducted between 2003 and 2014. We add to the literature by introducing a new time-varying instrumental variable to control for endogenous migration decisions, constructed as a composite of three variables that represent opportunities to work abroad: (i) the household's number of adult males, (ii) historic diaspora rates, and (iii) deviations of nighttime light intensity from its trend in migrant-receiving countries. We find a significant shift in domestic labor market activity from lower-status employment categories (not working at all, unpaid family work and manual labor) toward higher-status activities and entrepreneurship such as self-employment and becoming an employer within migrant-sending households.

Empowered mothers and co-resident grandmothers: Two fundamental roles of women impacting child health outcomes in Punjab, Pakistan.

We show that i) empowered mothers and ii) coresident grandmothers each benefit children's nutritional health measured by height-for-age z-scores (HAZ) and weight-for-age z-scores (WAZ) for age groups 5 years and less. First, using cross-sectional data from the Pakistan Demographic and Health Survey (PDHS) for the year 2017-18, we estimate the impact of empowered mothers on child health outcomes using an instrumental variable approach to correct for endogeneity. Empowerment is measured by two indices: as a sum of the questions that gauge both attitudinal and behavioral dimensions of female agency and also and using multiple correspondence analysis (MCA) for these same questions.

Impact of prenatal exposure to Ramadan on disability in Pakistan among adults age 18-64.

Purpose: Temporary disruptions to eating and sleeping patterns due to exposure to Ramadan during pregnancy have been shown to increase the probability of disability and chronic health problems later in life. This study aims to analyze the intent-to-treat effect of prenatal exposure to Ramadan (the Islamic month of fasting) on individual disabilities for individuals age 18 to 64 across three provinces encompassing 94% of Pakistan's population.

Subjects And Methods: The study uses observational data from 2017 to 2019 by the UN-supported Multiple Indicator Cluster Survey (MICS) on 187,265 adults in Punjab, 71,895 adults in Sindh, and 91,283 in Khyber Pakhtunkhwa, Pakistan.

The Impact of Prenatal Exposure to Ramadan on Child Anthropomorphic Outcomes in Pakistan.

Objectives: This study analyzes the intent-to-treat effect of prenatal exposure to Ramadan (the Islamic month of fasting) on outcomes including stunting and underweight for children under age 5 years in Pakistan born between 2003 and 2018.

Methods: The study uses observational data from four rounds of the UN-supported Multiple Indicator Cluster Survey (MICS) data collected on 204,186 children under-5 from Punjab, Pakistan in 2007-2008, 2010-2011, 2013-2014, and 2017-2018. Excluding data on outliers and observations with incomplete data, multivariate logistic regression analysis was conducted on the appended cross-sectional data of 179,943 children under-5 to assess the risk of stunting or underweight according to the month of gestation coinciding with Ramadan.

Effects of birth order and son preference on utilization of pre- and post-natal health inputs in Punjab.

The study planned to determine the roles of birth order and son preference on receiving prenatal, delivery care, and postnatal child health inputs, using cross-sectional data collected by the Multiple Cluster Indicators Study Punjab related to year 2011 from all districts of the Punjab province of Pakistan. Prenatal inputs, safe delivery care, and total child health inputs fall with higher birth order of the child, though these trends are diminished when household socioeconomic controls are added. Prenatal inputs increase with maternal education, household head education, and household wealth.

ESTIMATING THE HEALTH AND SOCIOECONOMIC EFFECTS OF COUSIN MARRIAGE IN SOUTH ASIA.

The effects of marriage between biological relatives on the incidence of childhood genetic illness and mortality are of major policy significance, as rates of consanguinity exceed 50% in various countries. Empirical research on this question is complicated by the fact that consanguinity is often correlated with poverty and other unobserved characteristics of households, which may have independent effects on mortality. This study has developed an instrumental variables empirical strategy to re-examine this question, based on the concept that the availability of unmarried cousins of the opposite gender at the time of marriage creates quasi-random variation in the propensity to marry consanguineously.
