摘要：
We quantify the roles of increasing returns and trade costs in medical services. Using data on millions of Medicare claims, we document that “imported” medical procedures—defined as a patient's consumption of a service produced by a medical provider in a different region—constitute about one-fifth of US healthcare consumption. Larger markets specialize in the production of less common procedures, and these procedures are more traded between regions. These patterns reflect economies of scale: larger regions produce higher-quality care because they serve more patients. Revealed-preference estimates of quality, which are positively related to external measures of quality of care, have a scale elasticity around 0.7. We use these estimates to evaluate the proximity-concentration tradeoff associated with various policy options for improving access to medical care.
