Traditional HIV/AIDS education campaigns have not been completely effective in curtailing new infections. One potential reason behind this is that most of the infections occur among individuals who are willing to take risks when it comes to sexual behaviour, and campaigns have failed to specifically target these people. This column describes a new HIV intervention trialled in Lesotho that used a lottery to target such individuals and incentivise safer practices. HIV incidence was reduced by more than a fifth in treatment groups over the trial period. These results, combined with practical and cost advantages, suggest that such interventions could prove invaluable in the fight against HIV.

Upward social mobility is widely sought but often elusive in highly mobile societies like the US. While previous work has focused on intergenerational transmission of income levels and social prosperity among natives and immigrants, this column studies the intergenerational transmission of health. There is substantial persistence in health status for both natives and immigrants. However, as immigrant families remain in the US for more generations, their children’s health tends to resemble more the health of native children and less the health of their mothers.

There is ample empirical evidence showing that poor mental health is increasing, but the impact of this on long-run productivity and its implications for the labour market are not well researched. This column outlines two ways in which labour market research can contribute to the study of the impact on mental health of working conditions. It also identifies several channels related to working conditions that affect mental health, and argues that deteriorating mental health adversely affects corporate performance in the long run.

Despite ample research on the effects of minimum wage increases on employment, there has been little consensus on the effects of such increases on workers’ broader welfare, and in particular on their health and that of their families. This column analyses comprehensive data from the US on the effects of minimum wage increases on the health of children born to low-income workers. It finds that the increases have a significant positive impact on birth weights. This has important policy implications, with infant health acting as a reliable indicator of future health.

The US health insurance market is becoming less competitive due to mergers and withdrawal of services from certain states. This column examines how this affects consumers through insurance premiums and hospital reimbursement rates. Using employer-sponsored insurance data from California, it finds that the relationship between insurer competition and health care spending depends on institutional and market structure. If premiums can be constrained through effective regulation or negotiation, then reduced competition might lead to lower costs. Absent such constraints, consumers will likely be harmed.

Does giving people a health test lead to a change in their behaviour? In this video, Zlata Tanović discusses the challenges of collecting medical data. The video was recorded during a UNU-WIDER conference on 'Human capital and growth' held in June 2016.

Food consumption has increased worldwide, concurrent with rising obesity rates. This column draws on five decades of data from 209 countries to identify trends in overall caloric intake as well as the types of foods that provide the calories. The data reveal differences between socioeconomic groups and regions that are likely to have important implications for population health. Preliminary analysis of the economic correlates suggests that GDP per capita, labour force participation and healthcare measures explain much of the rise in caloric intake.

Progress in adopting smoking bans across the US has been slow, despite a majority of Americans supporting a ban in public places. This column uses aggregate and establishment-level data from Texas to examine the economic effects of smoking bans on bars and restaurants. The results suggest that bars and restaurants are not adversely affected by the adoption of a ban.

‘Defensive medicine’ refers to doctors performing excessive tests and procedures because of concerns about potential malpractice liability. Advocates for reform of the liability system typically argue that this raises healthcare costs with few expected benefits for patients. This column explores how tort reform laws designed to curb defensive medicine affect innovation in medical devices. US states that introduce such laws see a reduction in medical device patenting, suggesting that high liabilities actually encourage innovation.

What prevents families from investing in health products that can save lives? In this video, Pascaline Dupas shows that a full subsidy of health products increases the number of people benefitting from health products. This video was recorded during a UNU-WIDER conference on “Human capital and growth” held in June 2016.

The health effects of pollution in terms of hospitalisations, mortality and morbidity are well researched, but not so much is known about the less severe effects of pollution on workers’ health. This column uses evidence from China to analyse the impact of pollution on productivity, finding that high levels of pollution reduce the productivity even of indoor workers. Reducing pollution is not just welfare-improving for society, it is also of financial benefit to the economy.

The rise in obesity has largely been attributed to an increase in calorie consumption. This column investigates this claim by examining the evolving consumption and lifestyles of English households between 1980 and 2013. While there has been an increase in calories from restaurants, fast food, soft drinks, and confectionery, there has been an overall decrease in total calories purchased. This decline in calories can be partially rationalised with weight gain by the decline in the strenuousness of work and daily life, and increasingly sedentary lifestyles.

Inequalities in mortality rates are a good indicator of economic wellbeing, but most of the existing literature does little to distinguish between developments in infants and adults. This column uses extensive US data to analyse mortality trends across all age groups. It finds that the health of the next generation in the poorest areas of the US has improved significantly and the race gap has declined significantly. Underlying explanations include declines in the prevalence of smoking and improved nutrition, and a major cause is social policies that target the most disadvantaged.

Although not a nudge, the ‘soda tax’ in the UK can nonetheless be justified in part on behavioural grounds. This column analyses the potential effectiveness of the soda tax in reducing consumption. As a behavioural instrument, the tax does not go far enough, and is in fact regressive. A comprehensive junk food tax should be introduced instead, accompanied by nudges, ‘healthy’ subsidies, and regulation of ‘super-sizing’ practices.

Obesity, particularly in children, is a major health concern in many developed economies, where it presents a costly risk to health services. Any policy response must take into account the inter-generational transmission of overweightness and obesity to children. This column uses evidence from the Health Survey of England to assess the extent to which nature and nurture factors play a role in the overweightness of children. It finds that any effective policy action must tackle parental overweightness to lower rates of overweightness in children.

Industrialisation has been the key to modern economic growth and rapidly rising incomes, but some question whether it is always a blessing when taking a broader view of human wellbeing. While the recent rise of China and other Asian economies has transformed the lives of millions, the experience of Britain in the 19th century shows a more mixed picture of development. This column presents a unified framework for measuring British wellbeing over the period 1780-1850, which shows that better health and higher income levels alternated in improving overall wellbeing, until declining health in the 1840s led to stagnating wellbeing.

Many countries are increasing the age at which people can start claiming state-funded pensions. One objection often raised is that such policies are unfair because some will be too unhealthy to remain in paid work. This column compares employment rates in England of older people today to those of earlier generations, and also to those of younger people today. These comparisons suggest that a significant minority of older people appear to be unable to work on the grounds of health alone.
We are looking for original/unpublished scientific papers that shed new light on the topic “Overweight and Obesity in Asia and the Pacific.” All papers should be based on sound theoretical and/or empirical evidence.
The papers should be related to, though not limited to, one the following topics:
-Determinants of overweight and obesity across countries or within countries across different stratifications (age, gender, education, income, rural/urban, etc.) as well as across time.
-Country studies on the cost of illness, including the costs for health systems as well as the economic costs (including macroeconomic impact) of overweight and obesity.
-Case studies of experiences to reduce overweight and obesity implementing non-market (such as education) or market measures (such as sugar tax).

Stress and violence during the nine months in utero has been widely shown to have important effects on child development. To date this research has largely focused on extreme and relatively rare events. This column uses data from Brazil to explore how exposure to day-to-day violence can affect birth weight. The birth weight of newborns whose mothers are exposed to a homicide during their first trimester is significantly lower. This effect is smaller for mothers who live in more violent neighbourhoods, consistent with the interpretation that violence is more stressful when it is rare.

Pollution levels are orders of magnitude higher in lower-income countries than in the developed world. This means that studies of the health effects of pollution based on data from the latter will not necessarily be relevant to the former. This column reports on the effect of air pollution on infant mortality in Mexico City. Significant effects are found that are much larger than found in earlier work based on US data. These findings highlight the potential pitfalls of naively extrapolating findings from high-income to developing countries.
