What does CBA stand for
Cost Benefit Analysis
Defenition
- Tool to decide whether one outcome is better that another from society’s perspective based in economic value
- in policy processes - env taxes and defenses of rivers and coasts
Describe the methodology, and the 6 steps
- Project defenition
- what is being analysed
- whose welfare in being considered
- time period - Identification of physical impacts of the project/policy
- identify the resource allocation in physical magnitudes - Monetary valuation of inputs
- all relevant effects are expressed in monetary values so they can be aggregated
- to value impacts in terms of their marginal social cost or marginal social benefit - Discounting
- discounting cost and benefits
- concerning the monetary values into present value terms
- sam time value of money - Applying Net Present Value test
- to determine whether future costs outweigh the present benefits - Sensitivity analysis
- uncertainties because of non-perfect foresights
- re-calculate NPV when values of key-parameters are changed ex discount rate
Describe NPV
NPV = net present value
- to determine wether future costs outweigh present benefits
NPV = sum(discounted gain) - sum(discounted losses)
if NPV < 0 there is no gain
Problems with CBA
- ecosystem complexity
- Discounting and discounting rate - what rate and should it be done?
- Ethically challenging - should wildlife have monetary value
- many studies of low quality
- for env. consequences poorly designed
