Benefit-Cost Analysis Of Environmental Projects: A Plethora Of Systematic Biases, Philip E. Graves
Benefit-Cost Analysis Of Environmental Projects: A Plethora Of Systematic Biases, Philip E. Graves
PHILIP E GRAVES
There are many reasons to suspect that benefit-cost analysis applied to environmental policies will result in policy decisions that will reject those environmental policies. The important question, of course, is whether those rejections are based on proper science. The present paper explores sources of bias in the methods used to evaluate environmental policy in the United States, although most of the arguments translate immediately to decision-making in other countries. There are some “big picture” considerations that have gone unrecognized, and there are numerous more minor, yet cumulatively important, technical details that point to potentially large biases against acceptance on benefit-cost …

Most economic research on life expectancy focuses on building forecasting models using mortality trends or constructing parameter life expectancy models with samples of individuals. We here provide a cross-sectional model of life expectancy, using a comprehensive worldwide sample, which analyses the impact of country level variables on average life expectancy. The model variants suggest robustly that proxies for technology, education, disposable income and healthcare all have a significant and positive effect on country variation in average life expectancy, at all income levels. A proxy for the health risks/epidemics factor is significantly negative. This analysis provides information of use to governments, …
