题目:Does the expectation of losing eligibility for generous health insurance plans in the future change individuals’ healthcare consumption?
摘要:
Reforms of public healthcare systems are constantly underway in modern society. While a vast majority of previous studies have focused on the consequences of the new policies after their implementation, few have considered the impact of anticipated future changes in public healthcare systems on current healthcare behaviors. How consumers respond to future incentives is a fundamental question in healthcare policy research yet not well understood. We investigate the effect of losing eligibility for generous health insurance protection in the future on present healthcare consumption. Leveraging a quasi-experiment in a public healthcare program reform, we use difference-in-differences methods to study the healthcare behaviors of those are about to lose health insurance eligibility in the next calendar year. The results confirm an increase in their healthcare consumption, and this ramp-up in healthcare expenses can be explained by a shift from low-quality facilities to high-quality ones. Our findings shed light on the necessity to consider individuals’ forward-looking behaviors when modifying public healthcare policies.

题目:医疗服务通胀与生产率——基于鲍莫尔成本病理论的分析
摘要:
各国医疗服务费用快速增加,大多增速超过同期国内生产总值,导致医疗服务“通胀”成为全球性的普遍趋势。Baumol (1967)成本病理论为解读此类现象提供了重要洞见。本文基于该理论讨论中国医疗服务费用增长中的价格通胀问题。根据中国省级面板数据,基于鲍莫尔成本病理论的5项假说,本文首先讨论中国整体经济中的鲍莫尔成本病问题,进而使用Malmquist方法计算医疗服务行业生产率增长率,验证并讨论医疗服务行业中鲍莫尔成本病的表现形式。实证研究表明:中国整体经济体现出明显的鲍莫尔成本病特征,生产率增长更低时,名义产出、从业人员工资增长水平更低,从业人员增长数更高。医疗服务行业表现出类似的鲍莫尔成本病特征,生产率增长更低时,实际产出、名义产出、从业人员工资增长水平更低,从业人员增长数更高。相对整体经济水平,医疗服务行业低生产率增长的影响更多被行业工资水平变化而非服务价格所吸收。与外国相关研究结果相比,中国医疗服务行业成本病程度相对较轻。分地区的分析表明,医疗服务行业的鲍莫尔成本病在西部地区相对更明显。

摘要:
Motivated by several recent papers on oligopoly theory, we characterize geometric properties of a class of inequalities involving the product of two integrals of the probability density quantile function and its reciprocal. Through three applications, we illustrate how our characterization can help enrich our understanding of the existing findings and shed some new insight, regarding the extent to which market inefficiency depends on the properties of the distributions of consumer heterogeneity.
