May 2017Is Preventive Care Worth the Cost? Evidence from Mandatory Checkups in Japan
with Katsuhiko Nishiyama, Brian Chen, Karen Eggleston: w23413
Using unique individual-level panel data, we investigate whether preventive medical care triggered by health checkups is worth the cost. We exploit the fact that biomarkers just below and above a threshold may be viewed as random. We find that people respond to health signals and increase physician visits. However, we find no evidence that additional care is cost effective. For the “borderline type” (“pre-diabetes”) threshold for diabetes, medical care utilization increases but neither physical measures nor predicted risks of mortality or serious complications improve. For efficient use of medical resources, cost effectiveness of preventive care must be carefully examined.
November 2005Drug Advertising and Health Habit
with Ginger Zhe Jin: w11770
We examine the effect of direct-to-consumer advertising (DTCA) of drug treatment on an important health habit, physical exercise. By learning the existence of a new drug treatment via DTCA, rational consumers may become careless about maintaining healthy lifestyles. Using the National Health Insurance Survey (NHIS) and MSA-level DTCA data, we find that the DTCA related to four chronic conditions -- diabetes, high cholesterol, over weight, and hypertension -- reduce the likelihood of engaging in moderate exercise. This suggests the possibility that DTCA does not only affect pharmaceutical demand in the short-run, but also have long-run impacts on people's health by affecting their daily routines.
