A critic of CBA may say this: what is the point of entering into the philosophically loaded argument of intergenerational equity when we still have, as shown in Chapter 7 , a long way to go in addressing the practical problems of estimating the costs (i.e., environmental damage) and/or benefits (i.e., environmental conservation). We should stop pretending to use a full-blown cost-benefit analysis (CBA) and instead use cost effectiveness analysis (CEA). What is cost-effectiveness analysis? How does it differ from CBA? Do you agree with the position taken by the above type of criticism of CBA? Discuss.
