Symposium Introduction: Papers on ‘Modeling National Health Expenditures’
这篇引言回顾了国家卫生支出研究50多年来的发展，介绍四篇推动该领域的新研究，并指出未来研究的方向，对卫生经济学和政策评估者有价值。
Significant contributions have been made since the World Health Organization published Brian Abel-Smith's pioneering comparative study of national health expenditures more than 50 years ago. There have been major advances in theories, model specifications, methodological approaches, and data structures. This introductory essay provides a historical context for this line of work, highlights four newly published studies that move health economics research forward, and indicates several important areas of challenging but potentially fruitful research to strengthen future contributions to the literature and make empirical findings more useful for evaluating health policy decisions.
