title: Explaining the Persistence of Health Disparities: Social Stratification and the Efficiency-Equity Trade-off in the Kidney Transplantation System.
abstract: Why do health disparities persist when their previous mechanisms are eliminated? Fundamental-cause theorists argue that social position primarily improves health through two metamechanisms: better access to health information and technology. I argue that the general, cumulative, and embodied consequences of social stratification can produce another metamechanism: an efficiency-equity trade-off. A case in point is kidney transplantation, where the mechanisms previously thought to link race to outcomes--ability to pay and certain factors in the kidney allocation system--have been greatly reduced, yet large disparities persist. I show that these current disparities are rooted in factors that directly influence posttransplant success, placing efficiency and racial/ethnic equity at cross-purposes.
