Rising obesity is a pressing global public health problem responsible for rising health care costs and in some countries one of the leading causes of preventable deaths. There is substantial evidence that obese people are less likely to be employed and, when employed, earn lower wages. There is some evidence that the lower earnings are a result of discriminatory hiring and sorting into jobs with less customer contact. Understanding whether obesity is associated with adverse labor market outcomes and ascertaining the source of these outcomes are essential for designing effective public policy.

A non-trivial portion of traffic fatalities involve alcohol or illicit drugs. But does substance use—which is linked to depression, suicide, and criminal activity—also reduce academic performance? Recent studies suggest that the consumption of alcohol has a negative effect on the grades of university students. Likewise, there is evidence that marijuana use reduces the academic performance of university students. Although students who use illicit substances are more likely to drop out of high school than those who do not, this may reflect the influence of other, difficult-to-measure factors at the individual level, such as personality.

Do workplace programs help reduce worker sickness absence? Many programs are based on the principle that the employee’s decision to report an absence can be influenced if it is costly to be absent. Firms can reduce absenteeism by implementing broad programs, including performance pay, general improvements of working conditions, and strengthening workers’ loyalty to the firm. Specific programs, such as grading partial absence, seem to be effective at reducing long-term absences. However, firms will be less inclined to implement such programs if they can shift the financial burden to social security programs.

Discrimination is a complex, multi-factor phenomenon. Evidence shows widespread discrimination on various grounds, including ethnic origin, sexual orientation, gender identity, religion or beliefs, disability, being over 55 years old, or being a woman. Combating discrimination requires combining the strengths of a range of anti-discrimination policies while also addressing their weaknesses. In particular, policymakers should thoroughly address prejudice (taste-based discrimination), stereotypes (statistical discrimination), cognitive biases, and attention-based discrimination.

Retirement offers the opportunity to give up potentially risky, unhealthy, and/or stressful work, which is expected to foster improvements in retirees’ health. However, retirement also bears the risk that retirees suffer from the loss of daily routines, physical and/or mental activity, a sense of identity and purpose, and social interactions, which may lead them to adopt unhealthy behaviors. Depending on the relative importance of the different mechanisms, retirement may either improve or cause a deterioration of retirees’ health, or eventually have no effect on it at all.

Understanding the impacts of climate change on time allocation is a major challenge. The best approach comes from looking at how people react to short-term variations in weather. Research suggests rising temperatures will reduce time spent working and enjoying outdoor leisure, while increasing indoor leisure. The burden will fall disproportionately on workers in industries more exposed to heat and those who live in warmer regions, with the potential to increase existing patterns of inequalities. This is likely to trigger an adaptation, the scope and mechanisms of which are hard to predict, and will undoubtedly entail costs.

Acceptance of one’s gender identity and congruence between one’s gender identity and outward appearance are associated with less adverse mental health symptoms, and greater life and job satisfaction. However, trans people are subject to human rights violations, hate crimes, and experience higher unemployment and poverty than the general population. Trans people often feel that they are citizens who are not allowed to be themselves and practice their authentic identity. Many biased treatments of trans people could be attenuated if legal protections and inclusive workplace practices were in place.

The literature on the economics of religion finds that increased religious participation or religious density is associated with positive socio-economic outcomes such as increased earnings, educational attainment, and lower engagement in risky behaviors. The literature suggests that this relationship is causal, and that the gains from religion often tend to be accrued among low-skill or marginalized youth groups. In turn, as education and income increase, societies become more secular. Will the positive outcomes associated with religion disappear as western societies become more secularized?

The link between air pollution and human health is well-documented in the epidemiology and economic literature. Recently, an increasing body of research has shown that air pollution—even in relatively low doses—also affects educational outcomes across several distinct age groups and varying lengths of exposure. This implies that a narrow focus on traditional health outcomes, such as morbidity and mortality, may understate the true benefit of reducing pollution, as air pollution also affects scholastic achievement and human capital formation.

Environmental regulations are typically considered to be a drag on the economy. However, improved environmental quality may actually enhance productivity by creating a healthier workforce. Evidence suggests that improvements in air quality lead to improvements in worker productivity across a range of sectors, including agriculture, manufacturing, and the service sectors. These effects also arise at levels of air quality that are below pollution thresholds in countries with the highest levels of environmental regulation. The findings suggest a new approach for understanding the consequences of environmental regulations.
