Discrimination against doctors is important but scantly studied. I report a field experiment which observes that customers discriminate against Black and Asian doctors when they choose healthcare providers, and that this can be substantially reduced by supplying information on physician quality. I evaluate customer preferences in the field with an online platform where cash-paying consumers can shop and book a provider for medical procedures based on a novel experimental paradigm. Actual paying customers evaluate doctor options they know to be hypothetical to be matched with a customized menu of real doctors, preserving incentives. Racial discrimination reduces patient willingness-to-pay for Black and Asian doctors by 12.7% and 8.7% of the average colonoscopy price respectively; customers are willing to travel 100-250 miles to see a white doctor instead of a Black doctor, and somewhere between 50-100 to 100-250 miles to see a white doctor instead of an Asian doctor. Providing signals of doctor quality reduces this willingness-to-pay racial gap by about 90%. Willingness-to-pay penalties on minority doctors are multiples of actual average racial quality differences and even the difference between doctors in highest and lowest quality levels. This field evidence shifts the focus beyond traditional taste-based and statistical discrimination to include behavioral mechanisms like biased beliefs and deniable prejudice. Discrimination against Black doctors are higher for non-college-graduate customers and residents in zipcodes that voted for the 2020 presidential candidate on the political right.  Actual booking behavior allows cross-validation of incentive compatibility of the stated preference elicitation.

We conduct a lab experiment that shows current rules regulating transplant centers (TCs) and organ procurement organizations (OPOs) create perverse incentives that inefficiently reduce both organ recovery and beneficial transplantations. We model the decision environment with a 2-player multi-period game between an OPO and a TC. In the condition that simulates current rules, OPOs recover only highest-quality kidneys and forgo valuable recovery opportunities, and TCs decline some beneficial transplants and perform some unnecessary transplants. Alternative regulations that reward TCs and OPOs together for health outcomes in the entire patient pool lead to behaviors that increase organ recovery and appropriate transplants.
