Research Seminar with Yashaswini Singh, PhD
Stress Testing Markets for Cardiac Care
Open to Penn Affiliates
The diffusion of technological innovation depends on price signals and prevailing regulations. We study their intersection in cardiac procedure markets––a high-stakes medical field with regular treatment advancements. When Medicare policy newly permits non-hospitals to compete against hospitals for cardiac services, physicians exposed to new facility entry not only perform targeted Medicare services at these facilities but also untargeted procedures across payers. Beyond setting substitution, we find market expansion and higher spending overall following deregulation, with heterogeneity tied to state-level laws and hospital-physician integration. Ultimately, policy shapes healthcare market entry, which impacts the availability of treatment options and imposes externalities.
Please note: Registration for this event is required. In-person attendance is strongly encouraged, although virtual access will be provided for all registrants.
