New Population Studies Working Paper

The research shows Non-Communicable Diseases (NCDs) are linked to aging and affluence and have replaced infectious diseases and malnutrition as the dominant causes of ill health and death in much of the world including India. The present study examines rising rates of two NCDs heart disease and diabetes. The following questions are addressed: Why has the prevalence of these two NCDs risen in recent years, whether social protection policies and restructuring of medical services can mitigate such surges in the near future, and whether lifestyle and dietary changes could be induced to further prevent the rising burden of these NCDs.

New Population Studies Working Paper

The research uses data from the Malawi Longitudinal Study of Families and Health to examine the relationship between mortality and fertility in Malawi - specifically the impact of individual-specific subjective mortality expectations on fertility choice.


Authors: Adeline DelavandeHans-Peter Kohler, and Ali Vergili


For decades, population research has been interested in the complex relationship between child mortality and fertility, with a key focus on identifying replacement behavior (fertility response to experienced child mortality) and hoarding behavior (fertility response to expected child mortality). Using unique data from the Malawi Longitudinal Study of Families and Health (MLSFH), we investigate the impact of individual-specific subjective infant mortality expectations on fertility choice. We instrument the potentially endogenous infant mortality expectations with the average of parents’ ratings of children’s health to address a potentially omitted variable bias such as parental taste for health. Consistent with the hoarding mechanism, we find that a 10 percentage point decrease in infant mortality expectations leads to a 14 percentage point decrease in the propensity to have a child in the next 2 years from a baseline propensity of 43%.

Helene Purcell co-authors a paper on Conscientiousness Matters

Postdoctoral fellow Helene Purcell co-authored a paper along with Justine Herve and Sneha Mani

Abstract: Personality traits play an important role in shaping labor market outcomes, but the associated behaviors that lead to these differences are understudied. In this paper, we examine the returns to the Big Five personality traits as well as the mechanisms through which personality affects employment and earnings. We find conscientiousness to be a significant predictor of both employment and earnings. We further show that the association between conscientiousness and earnings operates primarily through one specific behavior, namely, higher work intensity. Additionally, we are able to rule out selection into specific job types as potential channels for the positive relationship between conscientiousness and earnings.

Jeremy Greenwood co-authors a paper on the Role of Friends in the Opioid Epidemic

Research Associate Jeremy Greenwood co-authors a paper along with Effrosyni AdamopoulouNezih Guner, and Karen Kopecky

Abstract: The role of friends in the US opioid epidemic is examined. Using data from the National Longitudinal Survey of Adolescent Health (Add Health), adults aged 25-34 and their high school best friends are focused on. An instrumental variable technique is employed to estimate peer effects in opioid misuse. Severe injuries in the previous year are used as an instrument for opioid misuse in order to estimate the causal impact of someone misusing opioids on the probability that their best friends also misuse. The estimated peer effects are significant: Having a best friend with a reported serious injury in the previous year increases the probability of own opioid misuse by around 7 percentage points in a population where 17 percent ever misuses opioids. The effect is driven by individuals without a college degree and those who live in the same county as their best friends.

Jere Behrman co-authors a paper on Female Headship and Poverty in the Arab Region

Research Associate Jere Behrman co-authors a paper with Shireen AlAzzawiHai-Anh DangVladimir Hlasny, and Kseniya Abanokova

Abstract: Various challenges are thought to render female-headed households (FHHs) vulnerable to poverty in the Arab region. Yet, previous studies have mixed results and the absence of household panel survey data hinders analysis of poverty dynamics. We address these challenges by proposing a novel typology of FHHs and analyze synthetic panels that we constructed from 20 rounds of repeated cross-sectional surveys spanning the past two decades from Egypt, Iraq, Jordan, Mauritania, Palestine, and Tunisia. We find that the definition of FHHs matters for measuring poverty levels and dynamics. Most types of FHHs are less poor than non-FHHs on average, but FHHs with a major share of female adults are generally poorer. FHHs are more likely to escape poverty than households on average, but FHHs without children are most likely to do so. While more children are generally associated with more poverty for FHHs, there is heterogeneity across countries in addition to heterogeneity across FHH measures. Our findings provide useful inputs for social protection and employment programs aiming at reducing gender inequalities and poverty in the Arab region.

Abstract: Most minimum wage (MW) research focuses on wage and employment impacts in high-income countries. Little is known about broader impacts, including on parental and child health in low- and middle- income countries (LMICs) where most people affected by MWs live. This study studies MW effects on employment, earnings, parental health and child health in Indonesia, the third most-populous LMIC. Results include: MWs improve men’s earnings, parental hemoglobin, and child height-for age and reduce pregnancy complications. This study highlights nuanced but positive roles MWs may play in improving parental and child health, despite not directly affecting women’s earnings and labor supplies.

Min Kim authors a paper on financial literacy

Min Kim writes a paper on Financial Literacy, Portfolio Choice, and Wealth Inequality.

Abstract: I develop a general equilibrium model in which households allocate their wealth to safe and risky assets (“bonds” and “stocks”) and accumulate financial literacy to raise their risk-adjusted stock returns. Calibrated to match financial literacy and stock market participation rate of U.S. households, the model demonstrates that a policy subsidizing financial literacy acquisition increases short-run stock investments. In equilibrium, however, the resulting aggregate capital growth lowers the average equity premium, thereby moderating the subsidy’s impact. The policy mitigates wealth inequality by inducing heterogeneous portfolio adjustments across the wealth distribution. With the subsidy, the middle wealth quartiles acquire more financial literacy and shift their portfolios toward stocks. The top quartile attains its maximum literacy level prior to the subsidy and shifts toward bonds to compensate for lower stock returns. The ratio of total wealth held by the top quartile versus the rest of the population decreases.

Petra Todd Co-Authors a paper on understanding gender disparities in STEM majors and occupations

Research Associate Petra Todd co-authors a paper along with Shasha Wang.

Abstract: In the US, women for decades have gone to college at higher rates than men, but they are less likely to choose applied-STEM college majors or occupations. Using the NLSY79 and 97 datasets, this paper assesses the importance of adolescent skills and high school course-taking in explaining gender disparities in four-year college completion, college major, and occupational choice. It considers five cognitive skill areas (math, verbal, science, administrative, and mechanical) and one non-cognitive measure and examines how gender skill gaps evolve over a twenty-year time span. Logistic, CART and nonparametric random forest models are estimated to identify the skill sets, course-taking and family background characteristics that best predict educational and occupational choices. Results show that women are on average on par with men in mathematics skills and exceed men in verbal and noncognitive skills, but they lag behind in mechanical and, to a lesser extent, science skills. Estimates show that a combination of mathematics and mechanical skills along with intensive high school exposure to science and math courses are key predictors of choosing applied-STEM majors and careers. This paper also develops and implements a nonparametric decomposition approach to quantify how eliminating adolescent gender skill disparities would affect women’s and men’s entry into STEM fields.

Hans-Peter Kohler co-authors a paper on how to survive bad news

Research Associate Hans-Peter Kohler co-authors a paper along with Alberto Ciancio, Fabrice Kampfen, and Rebecca Thornton

Abstract: Providing personal health information allows individuals to take action to improve their health. If treatment is not available, however, being informed about having a life-threatening disease could lead to feelings of despair or fatalistic behaviors resulting in negative health outcomes. We document this possibility utilizing an experiment in Malawi that randomized incentives to learn HIV testing results in a context where anti-retroviral treatment (ART) was not yet available. Six years after the experiment, receiving an HIV+ diagnosis reduced survival rates by 23% points and this effect persists after 15 years. We show that HIV+ persons who learned they were HIV+ engaged in more risky health behaviors, have greater anxiety and a higher discount rate. We do not find any effects of receiving an HIV - diagnosis on survival.
