ABSTRACT
17.01 Cost evaluations are necessary for determining the economic feasibility of rural access infrastructure (RAI) projects, as well as for selecting the appropriate technology to be used in their execution. The evaluations may be in financial costs or economic costs. Financial costs are the actual outlay of funds for the project. When these costs are adjusted by deleting taxes and/or subsidies, and/or by applying shadow prices to foreign exchange costs and wages, they become economic costs.
