摘要：It is important that noneconomists understand and consider three key points regarding the use
of economic cost-benefit analysis. First, economists undertaking applied cost-benefit analyses use expected
values by necessity in forward-looking models. Second, economists tally changes in economic value, comparing
¡°with¡± and ¡°without¡± investment scenarios, using producer and consumer surplus. Third, marginal changes in
the ¡°nonmarket¡± components of consumer surplus can, and should, be quantified in monetary terms and
included in evaluations whenever possible. These three factors highlight the need for multidisciplinary research
on complex problems relating public investments to the social, cultural, health, and environmental impacts of
those investments.
