Cost-benefit analysis and valuation uncertainty
This thesis addresses the economic trade-offs between hydropower and fish production, based on an empirical assessment of the costs and benefits of changing the water flow of the Ume/Vindel River in northern Sweden at a major hydropower plant in ways that would reduce its production of electricity b...

This thesis addresses the economic trade-offs between hydropower and fish production, based on an empirical assessment of the costs and benefits of changing the water flow of the Ume/Vindel River in northern Sweden at a major hydropower plant in ways that would reduce its production of electricity but increase the number of wild salmon in the river. A theoretical framework for dynamic cost benefit analysis (CBA) is presented and applied to the salmon passage-hydropower production conflict. The approach has wider applicability than suggested here, and should be useful in other, similar contexts. To obtain estimates for the benefit of increasing the number of wild salmon the contingent valuation method (CVM) was applied. The CVM is a survey-based method developed for measuring values of non-market goods by using willingness to pay (WTP) questions.
