Scared to Death? Information Avoidance and Diagnostic Testing

The use of preventive care in the U.S. is half the recommended level. Previous economic studies suggest that price is not the only significant deterrent. In fact, empirical evidence suggests that some people are health information avoidant: they prefer not knowing information about their health even when the testing is free and very accurate. This study evaluates the roles of many contributors to an individual's demand for type-2 diabetes screening. To explain the puzzle of information avoidance, I apply insights from the economics theoretical literature to incorporate health anxiety, which represents the stress or disutility associated with the anticipation of bad outcomes, as another psychic cost of taking a test. With data from the Health and Retirement Study, I jointly estimate a set of quasi-structural equations derived from a forward-looking individual's optimization problem regarding diabetes screening. In the model, the individual chooses the number of doctor visits (at which a diabetes screening is a stochastic outcome) and lifestyle behaviors. Results suggest that health anxiety, as well as monetary and time costs, subjective health, and longevity expectations are each important contributors to an individual's diabetes screening behavior. I also evaluate multiple policy experiments aiming to improve screening behavior and population health using the estimated dynamic model.
