We introduce a measure of population health that is sensitive to inequality in both age-specific health and lifespan and can be calculated from a health-extended period life table. By allowing for inequality aversion, the measure generalises health-adjusted life expectancy without requiring more data. A transformation of change in the (life-years) measure gives a distributionally sensitive monetary valuation of change in population health and disease burden. Application to Sub-Saharan Africa between 1990 and 2019 reveals that the change in population health is sensitive to allowing for lifespan inequality but is less sensitive to age-specific health inequality. Allowing for distributional sensitivity changes relative burdens of diseases, reduces convergence between the burdens of communicable and non-communicable diseases, and so could influence disease prioritisation. It increases the value of health improvements relative to GDP.

We examine differences in the prescribing of psychiatric medications to lower-income and higher-income children in the Canadian province of Ontario using rich administrative data that includes diagnosis codes and physician identifiers. Our most striking finding is that conditional on diagnosis and medical history, low-income children are more likely to be prescribed antipsychotics and benzodiazepines than higher-income children who see the same doctors. These are drugs with potentially dangerous side effects that ideally should be prescribed to children only under narrowly proscribed circumstances. Lower-income children are also less likely to be prescribed SSRIs, the first-line treatment for depression and anxiety conditional on diagnosis. Hence, socioeconomic differences in the prescribing of psychotropic medications to children persist even in the context of universal public health insurance and universal drug coverage.

Young people in sub-Saharan Africa are particularly at high risk of sexually transmitted infections. Little is known about their preferences and even less about their association with risky sexual behaviour. We conducted incentivized economic experiments to measure risk, time and prosocial preferences in Zimbabwe. Preferences measured at baseline predict biomarker and self-reported measures of risky sexual behaviour gathered 12 months later. We find robust evidence that individuals more altruistic at baseline are more likely to be Herpes Simplex Virus Type-2 (HSV-2) positive 12 months later. Analysis by sex shows this association is driven by our sample of women. Having more sexual partners is associated with greater risk tolerance amongst men and greater impatience amongst women. Results highlight heterogeneity in the association between preferences and risky sexual behaviour.

Adjusting the valuation of life along the (i) person-specific (age, health, wealth) and (ii) mortality risk-specific (beneficial or detrimental, temporary or permanent changes) dimensions is relevant in prioritizing healthcare interventions. These adjustments are provided by solving a life cycle model of consumption, leisure and health choices and the associated Hicksian variations for mortality changes. The calibrated model yields plausible Values of Life Year between 154K$ and 200K$ and Values of Statistical Life close to 6.0M$. The willingness to pay (WTP) and to accept (WTA) compensation are equal and symmetric for one-shot beneficial and detrimental changes in mortality risk. However, permanent, and expected longevity changes are both associated with larger willingness for gains, relative to losses, and larger WTA than WTP. Ageing lowers both variations via falling resources and health, lower marginal continuation utility of living and decreasing longevity returns of changes in mortality.

Despite the growing prevalence of insufficient sleep among individuals, we still know little about the labour market return to sleep. To address this gap, we use longitudinal data from Germany and leverage exogenous fluctuations in sleep duration caused by variations in time and local sunset times. Our findings reveal that a one-hour increase in weekly sleep is associated with a 1.6 percentage point rise in employment and a 3.4% increase in weekly earnings. Such effect on earnings stems from productivity improvements given that the number of working hours decreases with longer sleep duration. We also identify a key mechanism driving these effects, namely the enhanced mental well-being experienced by individuals who sleep longer hours.

A major policy concern across public vaccination programs is non-compliance. Exploiting Danish population data and three national reforms in regression discontinuity designs, we document the effects of reminders for childhood vaccination coverage. Retrospective reminders are primarily effective for families with small children and when sent out close to the recommended vaccination age. Digital and postal reminders are equally effective. Prospective reminders increase timely vaccinations in later childhood and help reaching high coverage for new vaccines in increasingly complex vaccination programs. While reminders prompt additional preventive care for focal children, we find no spillovers to other health behaviors or relatives.

This paper uses the gradual implementation of a primary healthcare (PHC) intervention in Costa Rica to examine the long-term effect of PHC on mortality. Nine years after opening a primary care center, known as a Health Area, there was an associated 13% reduction in age-adjusted mortality rate in the assigned patient population. The effect was highest among adults over 65 years of age and for those with noncommunicable diseases, such as cardiovascular-related causes of death. We also show that as Health Areas opened, more individuals sought care at primary care clinics, while fewer sought care at emergency rooms; these changes may have partially mediated the effect of the intervention on mortality.

Prescription drug insurance increasingly imposes prior authorization (requiring providers to request coverage before claim approval) to manage utilization. Prior authorization has been criticized because of its administrative burden on providers. The primary alternative to managing utilization is imposing out-of-pocket (OOP) payment to incentivize beneficiaries to seek lower-cost care, effectively providing beneficiaries with partial insurance. Would beneficiaries prefer indirectly paying for prior authorization through higher premiums; or would they prefer prior authorization was replaced by higher OOP costs? This tradeoff depends on how much OOP costs could be displaced by prior authorization, which depends on their relative impact on demand. I estimate the effect of prior authorization and OOP costs on pharmaceutical demand in Medicare Part D, addressing endogeneity caused by unobserved drug quality and selection into plans. Despite criticism of prior authorization, I find that Medicare beneficiaries would prefer higher premiums to pay for prior authorization, over higher OOP costs.

Mandated minimum nurse-to-patient ratios have been the subject of active debate in the U.S. for over twenty years and are under legislative consideration today in several states and at the federal level. This paper uses the 1999 California nurse staffing mandate as an empirical setting to estimate the causal effects of minimum ratios on hospitals. Minimum ratios led to a 58 min increase in nursing time per patient day and 9 percent increase in the wage bill per patient day in the general medical/surgical acute care unit among treated hospitals. Hospitals responded on several margins: increased use of lower-licensed and younger nurses, reduced capacity by 16 beds (14 percent), and increased bed utilization rates by 0.045 points (8 percent). Using administrative data on discharges for acute myocardial infarction (AMI), I find a significant reduction in length of stay (5 percent) and no effect on the 30-day all-cause readmission rate. The null effect on readmissions suggests that length of stay declined not because hospitals were discharging AMI patients “quicker and sicker”, rather, AMI patients recovered more quickly due to an improvement in care quality per day.

Employers may respond to minimum wage increases by adjusting their health benefits. We examine the impact of state minimum wage increases on employer health benefit offerings using the 2002–2020 Medical Expenditure Panel Survey – Insurance/Employer Component data. Our primary regression specifications are difference-in-differences models that estimate the relationship between within-state changes in employer-sponsored insurance and minimum wage laws over time. We find that a $1 increase in minimum wages is associated with a 0.92 percentage point (p.p.) decrease in the percentage of employers offering health insurance, largely driven by small employers and employers with a greater share of low-wage employees. A $1 increase is also associated with a 1.83 p.p. increase in the prevalence of plans with a deductible requirement, but we do not find consistent evidence that other benefit characteristics are affected. We find no consequent change in uninsurance, likely explained by an increase in Medicaid enrollment.
