Abstract

Background: Value of a Statistical Life Year (VSLY) provides an important economic measure of an individual's trade-off between health risks and other consumption, and is a widely used policy parameter. Measuring VSLY is complex though, especially in low-income and low-literacy communities.

Methods: Using a large randomized experiment (N = 3027), we study methodological aspects of stated-preference elicitation with payment cards (price lists) in an extreme poverty context. In a 2 × 2 design, we systematically vary whether buying or selling prices are measured, crossed with the range of the payment card.

Results: We find substantial effects of both the pricing method and the list range on elicited VSLY. Estimates of the gross domestic product per capita multiplier for VSLY range from 3.5 to 33.5 depending on the study design. Importantly, all estimates are economically and statistically significantly larger than the current World Health Organization threshold of 3.0 for cost-effectiveness analyses.

Conclusions: Our results inform design choice in VSLY measurements, and provide insight into the potential variability of these measurements and possibly robustness checks.

极端贫困中统计生命年的价值:布基纳法索农村测量方法的随机实验。

背景:统计生命年值(Value of a Statistical Life Year, VSLY)是衡量个人健康风险与其他消费之间权衡的重要经济指标，是一个被广泛使用的政策参数。然而，衡量VSLY是复杂的，尤其是在低收入和低识字率的社区。方法:采用一项大型随机实验(N = 3027)，我们研究了极端贫困背景下支付卡(价格表)的陈述偏好诱导的方法学方面。在2x2设计中，我们系统地改变买卖价格是否被测量，与支付卡的范围交叉。结果:我们发现定价方法和清单范围对诱导的VSLY都有实质性影响。根据研究设计，对VSLY的人均国内生产总值乘数的估计在3.5至33.5之间。重要的是，所有估计值在经济上和统计上都显著大于世界卫生组织目前用于成本效益分析的阈值3.0。结论:我们的结果为VSLY测量的设计选择提供了信息，并提供了对这些测量的潜在变异性和可能的稳健性检查的见解。

期刊介绍： Population Health Metrics aims to advance the science of population health assessment, and welcomes papers relating to concepts, methods, ethics, applications, and summary measures of population health. The journal provides a unique platform for population health researchers to share their findings with the global community. We seek research that addresses the communication of population health measures and policy implications to stakeholders; this includes papers related to burden estimation and risk assessment, and research addressing population health across the full range of development. Population Health Metrics covers a broad range of topics encompassing health state measurement and valuation, summary measures of population health, descriptive epidemiology at the population level, burden of disease and injury analysis, disease and risk factor modeling for populations, and comparative assessment of risks to health at the population level. The journal is also interested in how to use and communicate indicators of population health to reduce disease burden, and the approaches for translating from indicators of population health to health-advancing actions. As a cross-cutting topic of importance, we are particularly interested in inequalities in population health and their measurement.
