Kurt Sweat defends his dissertation

Kurt Sweat defended his dissertation this week. As you can see in the picture below, we celebrated with the traditional toast, but instead of champagne we're drinking  In-N-Out milk shakes.

 



He and I are flanked by the other members of his committee: Itai Ashlagi, Paolo Somaini, Frank Wolak and Han Hong.  He was also advised by Dr. Chris Almond.

  His job market paper, and the other papers in his dissertation, all concern heart transplants.

Endogenous Priority in Centralized Matching Markets: The Design of the Heart Transplant Waitlist (Job Market Paper

[Link to current draft]

"Centralized matching markets that prioritize specific participants to achieve certain policy goals are common in practice, but priority is often assigned using endogenous characteristics of participants. In the heart transplant waitlist in the United States, the treatment that a patient receives is used to assign waitlist priority. Policymakers recently changed the prioritization in an attempt to reduce waitlist mortality by assigning higher priority to patients receiving specific treatments previously associated with high waitlist mortality. First, I document a significant response to waitlist incentives in treatments given and transplants that take place. Then, I develop and estimate a structural model of treatment and transplant choices to evaluate the effect of the policy change on patients' outcomes and doctors' decisions. I find three main results from my model. First, there is little change in aggregate survival, and the effect of the change has been mainly redistributive. Second, the change has effectively targeted patients with lower untransplanted survival, with these patients receiving higher expected survival under the current design. Third, the effect on survival is largely driven by changes in the decision to accept/decline offers for transplants rather than directly due to a change in treatment decisions. The policy implications suggest that future designs of the waitlist should disincentivize declining offers for transplants."


Welcome to the club, Kurt.
