Benefit-Cost Analysis Of Enviromental Projects: A Plethora Of Biases Understating Net Benefits, Philip E. Graves
Benefit-Cost Analysis Of Enviromental Projects: A Plethora Of Biases Understating Net Benefits, 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 …

If The Large Wta-Wtp Gap For Public Goods Is Real (And There Are Good Reasons To Think So) Conventional Welfare Measures Are Simply Incorrect, Philip E. Graves
If The Large Wta-Wtp Gap For Public Goods Is Real (And There Are Good Reasons To Think So) Conventional Welfare Measures Are Simply Incorrect, Philip E. Graves
PHILIP E GRAVES
A robust finding in economics is that decision-makers often exhibit a much smaller dollar willingness to pay (WTP) for an item than the minimum amount that they claim to be willing to accept (WTA) to part with it. The spread between these two numbers is particularly large for public goods, raising serious public policy concerns regarding which number, if either, is appropriate for valuing such goods. A traditional utility maximizing model is presented here that predicts–as both measures are currently calculated–that WTA will exceed WTP, quite plausibly by a substantial amount for public goods. Moreover, it is shown here that …
