Abstract

Why do low income patients tend to go to lower quality health care providers, even when they are free? We show that differential information about provider quality is an important determinant of this disparity. Our empirical strategy exploits the temporary presence of a website that publicly displayed summary star ratings of general practitioner (GP) offices in England. Regression discontinuity estimates show that patient demand responds sharply to the information on the website, and that this response is almost entirely driven by residents of low income neighborhoods. The results are consistent with high income patients having better private information about quality. We incorporate our estimates into a structural model of demand that allows for heterogeneity in information, preferences, and consumer inertia. We find that information differences explain 24 percent of the relationship between income and GP quality and reinforce disparities in access to care.
