February 2019The Roots of Health Inequality and The Value of Intra-Family Expertise
with Petra Persson, Maria Polyakova: w25618
Mounting evidence documents a stark correlation between income and health, yet the causal mechanisms behind this gradient are poorly understood. This paper examines the impact of access to expertise on health, and whether unequal access to expertise contributes to the health-income gradient. Our empirical setting, Sweden, allows us to shut down inequality in formal access to health care; we first document that strong socioeconomic gradients nonetheless persist. Second, we study the effect of access to health-related expertise – captured by the presence of a health professional in the extended family – on health. Exploiting “admissions lotteries” into medical schools and variation in the timing of degrees, we show that access to intra-family medical expertise has far-reaching health consequ...
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.
