Comparing health systems across industrialized nations, Hsiao applies political and economic theories to develop a structural framework of essential elements of health systems. His team uses econometric models to test various hypotheses and to estimate the extent to which each structural element influences health expenditures and health status. Employing his systemic framework, he is assisting Taiwan, Cyprus, Mexico, Colombia, China, and Sweden in their health systems reforms.
In developing nations, Hsiao's research focuses on the development of sustainable financing mechanisms to provide health care for the poor, rural population, and urban workers. With UNICEF's support, he collaborates with seven universities in China to conduct a nationwide study on health care financing and provision for 100 million poor Chinese. Meanwhile, with the support of The World Bank, he is launching a large scale social experiment on community financing for the rural Chinese population, involving 100 communities and two million people.
