February 2019The Roots of Health Inequality and The Value of Intra-Family Expertise
with Petra Persson, Maria Polyakova: w25618
Do differences in health literacy contribute to the widely documented health-income gradient? In the context of Sweden, we document a strong relationship between exposure to health-related expertise – captured by the presence of a health professional in the family – and health. Exposure to expertise raises preventive health investments throughout the lifecycle, improves physical health, and prolongs life. Two quasi-experimental research designs – admissions lotteries into medical school and variation in the timing of medical degrees – support a causal interpretation of these effects. We estimate that unequal exposure to health-related expertise may account for up to 18 percent of the population-wide health-income gradient.
November 2014Subjective Beliefs, Deterrence, and the Propensity to Drive While Intoxicated
with Frank Sloan: w20680
This study investigates causal effects of changes in subjective probabilities of being pulled over and involved in accidents if driving while intoxicated on individuals’ drinking and driving choices. We also examine how hypothetical changes in perceptions of sanction severity affect drunk driving by experiments randomizing the harshness of punishments. We find that higher perceived risks of being pulled over and involved in accidents deter drinking and driving. However, deterrence is limited to persons who are alcohol addicted, lack of self-control over drinking, and are more impulsive. No deterrent effect of harsher legal punishments is found on individuals’ drunk driving choices.
