This paper explores the role of gender heterogeneity in the social diffusion of obesity among adolescents and its policy implications. We propose a social interaction model which allows for gender-dependent heterogeneity in peer effects. Our empirical approach is consistent with the best response functions of a non-cooperative model where social interactions stem from the channel of pure spillover or pure conformity. We estimate the model using data on adolescent Body Mass Index and network-based interactions. Our approach allows us to account for network endogeneity. Our results show that peer effects are gender-dependent, and male students are particularly responsive to the weight of their female friends. According to simulations, reaching out to women results in an 8% increase in effectiveness in reducing overall BMI, based on the most conservative scenario. Thus, female-tailored interventions are likely to be more effective than a gender-neutral approach to fighting obesity in schools.

We estimate welfare weights for health to facilitate program evaluation allowing for aversion to health inequality and to health inequity by three non-health characteristics. In a UK general population sample, 569 online experiment participants distribute constrained resources to determine the health of hypothetical individuals distinguished by randomly generated resource productivity as well as sex, income and smoking (41,460 observations). We elicit beliefs about responsibility for income and smoking, and use their associations with the allocations to estimate responsibility-sensitive weights for health by those two characteristics. We find weak prioritisation of females’ health, moderate prioritisation of the health of poorer individuals and strong prioritisation of the health of non-smokers over that of smokers. Substantial aversion to health inequality lowers weights on females and non-smokers, who are health-advantaged, and raises the weight on the poor, who are health-disadvantaged. As beliefs about responsibility for income and smoking strengthen, weights on the poor decrease and weights on non-smokers significantly increase.

The paper examines whether, among inpatient psychiatric admissions in California, for-profit (FP) hospitals engage in cream skimming, i.e., selecting patients for some characteristic(s) other than their need for care, which enhances the profitability of the provider. We propose a novel approach to identifying cream skimming using cost outcomes. Naïve treatment effect estimates of hospital ownership type consist of the combined effects of differential patient case mix (selection) and hospital cost containment strategies (execution). In contrast, an instrumental variable (IV) approach can control for case mix and establish the causal effects of ownership type due to its execution. We interpret the difference between the naïve and IV treatment effects to be driven by FP hospitals’ selection based on unobserved patient case mix. Our findings on patient selection show that FP hospitals are more likely than their not-for-profit (NFP) counterparts to admit higher-cost patients (who tend to be less profitable under the existing inpatient psychiatric care payment systems), providing no evidence of cream skimming by FP hospitals. Furthermore, our estimates of hospital execution indicate that FP hospitals are more likely than NFP hospitals to deliver inpatient services at lower costs. These results may alleviate concerns about the recent proliferation of FP psychiatric hospitals, particularly regarding cream skimming in this market.

We provide new evidence on how child-related career interruptions affect long-term health behaviors by examining the impact of maternal leave duration on smoking habits across 14 European countries. Linking data on maternity and parental leave policies from 1960 to 2010 with survey data on mothers’ health behaviors, birth, and employment histories, we identify the effects of absence from work due to child birth on lifetime smoking in an instrumental variable framework based on within- and between-country variations in policies. We find that a one-month increase in leave duration raises the probability of a mother smoking later in life by 1.2 percentage points. Additionally, a one-month increase in child-related absence from work extends the lifetime duration of smoking by 7 months, the number of cigarettes smoked per day by 0.2 cigarettes, and the number of pack years by 0.6. We document potential non-linearities in these effects, suggesting that shorter leave durations may have a protective effect, while very long absence from work could promote harmful health behaviors. Heterogeneity analyses reveal that the observed effects are mediated by the partners’ lack of financial support around childbirth, while employment status and other socio-demographic characteristics do not play a significant role.

The effects of school closures on COVID-19 transmission remain unclear, even after the conclusion of the national Public Health Emergency. We use healthcare claims data from 130 million household-week observations linked to smartphone mobility data to measure the effects of changes in county-level visits to schools on COVID-19 outcomes. We use a triple-differences approach that leverages within-county differences in exposure between families with and without school-age children and find modest impacts. We find increases in COVID-19 infection rates, with larger differences in low-income and higher COVID-19 prevalence counties.

In this study, we examine the inter-generational effects of the 1994 Female Secondary School Stipend Program (FSSSP) on child health inputs and child health outcomes in Bangladesh. Prior studies have shown that the FSSSP significantly increased secondary schooling among rural girls. Applying a difference-in-differences model based on differential exposure to FSSSP by birth cohort and rural residence, we find that full immunization rates increased by 4.2 percentage points among children of mothers eligible for a stipend for 5 years relative to children of mothers who were not eligible, but there were no significant effects for children of mothers eligible for a stipend for only 2 years. We also find improvements in other health inputs (e.g., antenatal care) and in child health outcomes (e.g., mortality). We also explore changes in marriage, fertility, autonomy, labor supply, and media exposure, which may contribute to the observed improvements in child health.

Time Trade-Off (TTO) and Standard Gamble (SG) tasks are commonly used methods to measure utilities for health states (e.g., diabetes, being in a wheelchair). Importantly, however, the two methods have been shown to typically yield discrepant utilities for a given health state. Here we examine the cognitive processes underlying this utility gap by analyzing individuals’ attentional patterns when evaluating health states in the TTO and SG tasks. In an online experiment, each respondent completed both a TTO and an SG task and we used the process-tracing methodology Mouselab to record respondents’ attention allocation to the tasks’ attributes: health states and their durations (in both TTO and SG), and probabilities (in SG only). In the TTO task, attention was approximately balanced between the health state and duration attributes, whereas in the SG task, attention was focussed on the probability and the health state attributes. Individuals who paid more attention to the task-specific trade-off attribute (i.e., duration and probability in TTO and SG, respectively) seemed to be less willing to make those trade-offs, leading to higher utilities for the health states. Notably, the utility gap was associated with individual differences in attention allocation: respondents who adjusted their attention allocation less to the task-specific trade-offs produced more discrepant utilities between the TTO and SG tasks. Our findings underscore the key role of attentional processes in preference construction, highlighting that differences in the utilities people assign to health states could potentially be influenced by altering attention allocation.

Public health advocates warn that the rapid growth of legal markets for electronic nicotine delivery systems (ENDS) may generate a “gateway” to marijuana and harder drug consumption, particularly among teenagers. This study explores the effects of ENDS taxes on substance use. Analyses are based on difference-in-differences and event-study methods applied to both survey (Youth Risk Behavior Surveillance System and Behavioral Risk Factor Surveillance System) and administrative (Treatment Episode Data Set) data. Our results imply that a one-dollar increase in ENDS taxes (2023$) is associated with a 1.0 to 1.5 percentage point decline in teen marijuana use and in co-use of ENDS and marijuana. This result is consistent with e-cigarettes and marijuana being economic complements. We also find that youth responses to ENDS taxes, in terms of their ENDS use and spillovers into marijuana use, appear to moderate over the longer term. We find no evidence that ENDS taxes affect drug treatment admissions or consumption of illicit drugs other than marijuana such as cocaine, methamphetamine, or opioids.

Estimates of the impact of Certificate of Need (CON) laws on medical care have been inconsistent, possibly because not all CON laws apply to all services. Using an original dataset identifying imaging-related CON laws and a regression discontinuity design at state borders, we estimate the effects of CON on the use and quality of diagnostic imaging. Medicare beneficiaries in regulated states are less likely to receive any image and even less likely to receive low-value imaging than beneficiaries in unregulated states. High-value imaging is unaffected. Overall, CON for imaging reduces low-value care and leaves high-value care unchanged.

This paper examines belief imprecision in the context of COVID-19, when uncertainty about health outcomes was widespread. We survey a sample of young adults a few months after the onset of the pandemic. We elicit individuals’ minimum and maximum subjective probabilities of different health outcomes, and define belief imprecision as the range between these values. We document substantial heterogeneity in the degree of imprecision across respondents, which remains largely unexplained by standard demographic characteristics. To assess the behavioral impact of imprecise beliefs, we ask beliefs about future outcomes under hypothetical scenarios that feature different levels of protective behaviors. We find that individuals who expect protective behaviors to reduce not only the subjective probability of a negative health outcome, but also the degree of imprecision associated with it, behave more protectively.
