As a labor and health economist, Aizer has an interest in child health and well-being. Descending from the bad parental health, maternal disadvantage leads to the poor health of the children at birth. From this the authors found that the male children of the accepted applicants lived longer, got more years of schooling, were less likely to be underweight and had higher income than that of the rejected mothers. They found that the exposure to high levels of
stress hormone negatively affects the offspring's cognition, health and educational attainment. Aizer also published an article focusing on
adult supervision and child behavior, examining the issue of children spending their school years without adult supervision due to the growth in the number of
women entering the workforce and the high cost of
child care. In 2015, Aizer published an article on
juvenile incarceration in the
Quarterly Journal of Economics with
Joseph J. Doyle Jr. In this study, they estimate the effects of juvenile incarceration on the completion of high school and adult recidivism by analyzing the incarceration tendency of randomly assigned judges. Together, they found incarceration of juveniles significantly reduces rates of returning to school while increasing the frequency of juveniles classified as emotionally or behaviorally disordered when juveniles do return to school. == Selected works ==
