01-2016: The Vaccination Kuznets Curve: Rise and Fall of Vaccination Rates with Income

This paper presents a new stylized fact about the relationship between income and childhood vaccination. It shows that vaccination rates initially rise but then fall as per capita income increases. This pattern is observed in country-level data from the WHO, and in individual and county-level data in the U.S. Both low and high-income parents are less likely to follow the standard vaccination schedule although for different reasons. To shed light on these parents' decisions, I develop a simple model and show how substitutes for vaccination such as avoidance measures and medical care could be responsible for this finding.
