Disease outbreaks, healthcare utilization, and on-time immunization in the first year of life.

This paper examines the determinants of parental decisions about infant immunization. Using the exact timing of vaccination relative to birth, we estimate the effects of local pertussis outbreaks occurring in utero and during the first two months of life on the likelihood of on-time initial immunization for pertussis and other diseases. We find that parents respond to changes in perceived disease risk: pertussis outbreaks within a state increase the rate of on-time receipt of the pertussis vaccine at two months of age, particularly among low-socioeconomic status (SES) subgroups.

Short-run effects of job loss on health conditions, health insurance, and health care utilization.

Job loss in the United States is associated with reductions in income and long-term increases in mortality rates. This paper examines the short-run changes in health, health care access, and health care utilization after job loss that lead to these long-term effects. Using a sample with more than 10,000 individual job losses and longitudinal data on a wide variety of health-related outcomes, we show that job loss results in worse self-reported health, activity limitations, and worse mental health, but is not associated with statistically significant increases in a variety of specific chronic conditions.
