¥Both B-C and C-E use discounting
¥C-E compares several alternatives
¥C-E – Maximize
benefits with fixed costs/resources, or
¥C-E – Minimize
cost/resources with fixed benefit
¥C-E sometimes can better deal with common
asymmetry of benefit and
cost data, i.e., often (environmental/ecosystem) costs are better know than
(environmental/ecosystem) benefits.
