A CONSISTENT DECOMPOSITION OF THE REDISTRIBUTIVE, VERTICAL, AND HORIZONTAL EFFECTS OF HEALTH CARE FINANCE BY FACTOR COMPONENTS
针对医疗融资研究中各融资工具贡献之和与总效应不匹配的问题，提出基于夏普利值的分解方法，实现所有效应的可加性，并揭示不同工具对系统公平性变化的相对贡献，有助于政策制定者实现公平的医疗融资。
In studies on the redistributive, vertical, and horizontal effects of health care financing, the sum of the contributions calculated for each financial instrument does not equal the total effects. As a consequence, the final calculations tend to be overestimated or underestimated. The solution proposed here involves the adaptation of the Shapley value to achieve additive results for all the effects and reveals the relative contributions of different instruments to the change of whole-system equity. An understanding of this change would help policy makers attain equitable health care financing. We test the method with the public finance and private payments of health care systems in Denmark and the Netherlands.
