Influenza vaccination could be a cost-effective way to reduce costs in terms of human lives and productivity losses, but low take-up rates and vaccination unintentionally causing moral hazard may decrease its benefits. We ran a natural field experiment in cooperation with a bank in Ecuador,...

We analyze the effects of a vaccination program providing free flu vaccine to individuals aged 65 or more on take-up behavior and hospitalization. Using both administrative and survey data, we implement a regression discontinuity design around the threshold at age 65, and find that the effect of...

This paper examines the economic impact of a tuberculosis control program launched in Norway in 1948. In the 1940s, Norway had one of the highest tuberculosis infection rates in Europe, affecting about 85 percent of the inhabitants. To lower the disease burden, the Norwegian government launched...

We examine the impact of new medical information on drug safety on preventive health behavior. We exploit the release of the findings of the Women's Health Initiative Study (WHIS) – the largest randomized controlled trial of women's health – which demonstrated in 2002 that long-term Hormone...

We study the impact of a mixed capitation model known as the Family Health Organization (FHO) on selected quality and quantity outcomes relative to an enhanced fee-for-service model known as the Family Health Group (FHG) among primary care physicians in Ontario, Canada. Using a panel of...

We study the efficiency in health systems generated by community health teams, a common strategy in low- and middle-income countries for primary healthcare delivery. We exploit the rollout of a nation-wide expansion of coverage to this model in El Salvador. Using a panel dataset of...

We conducted a unique randomized experiment to estimate the impact of alternative cash transfer delivery mechanisms on household demand for routine preventative health services in rural Burkina Faso. The two-year pilot program randomly distributed cash transfers that were either conditional or...

We use longitudinal data from the 1984 through 2007 waves of the Panel Study of Income Dynamics to examine how occupational status is related to the health transitions of 30 to 59 year-old U.S. males. A recent history of blue-collar employment predicts a substantial increase in the probability...

We study risk attitudes, ambiguity attitudes, and time preferences of 661 children and adolescents, aged ten to eighteen years, in an incentivized experiment. We relate experimental choices to field behavior. Experimental measures of impatience are found to be significant predictors of health...

We show that individuals who are in poorer health, independently from smoking, are more likely to start smoking and to smoke more cigarettes than those with better non-smoking health. We present evidence of selection, relying on extensive data on morbidity and mortality. We show that health...
