What is the meaning of technical consistency in the appraisal criteria?

Question

Especially in making a project proposal for the socio economic assessment

Answer 1

Assumptions must be consistent with each other. For example, if you compute cash flows in nominal terms, the discount rate you use must also be a nominal rate (i.e., not adjusted for inflation); if you compute cash flows in real (i.e., inflation-adjusted) terms, discount rate must also be inflation-adjusted.
