Failures and lessons learned from the medical school quota expansion policy under the Yoon Suk Yeol administration

South Korea offers a valuable case for examining why health reforms facing strong physician opposition can produce different outcomes. This commentary compares the 2000 Separation of Drug Prescribing and Dispensing (SPD) with the recent medical school quota expansion using Mark Moore's public value framework. We assess how public value, the authorizing environment, and operational capacity shaped the trajectories of the two reforms. SPD articulated a clear patient-safety rationale, secured broad political and social authorization, and developed legal, financial, and organizational mechanisms that supported implementation. By contrast, medical school quota expansion combined strong initial public support with contested policy logic, limited stakeholder authorization, and insufficient capacity to expand medical education or direct additional physicians toward underserved specialties and regions. The comparison also shows how earlier policy settlements shaped expectations and bargaining behavior in subsequent reform. Durable health workforce reform therefore requires alignment among public legitimacy, political authorization, and operational capacity.
