In this presentation Dale and Kerry explore the history of the ex-ante economic analysis of large dams through the discussion of six key developments that have occurred since the 1950s:
- adding systems analysis
- incorporating multiple objectives
- incorporating environment and social losses
- incorporating economy-wide linkages
- modelling non-cooperative behaviour
- dealing with uncertainty.
Current best practice in the application of ex ante economic analysis tries to address a subset of these developments, but there are no case studies or guidelines that an analyst can reference to learn how best to incorporate all six developments in the ex-ante appraisal of a new dam. We conclude that current professional practice in the ex-ante assessment of large dams has not yet caught up with the scholarly literature on these six developments and highlight the need for a new era of engagement by scholars and practitioners on this “old” challenging problem.
