The main conclusion of this project is that existing economic evaluations do not represent an adequate guide to resource allocation decisions when the distributional effects of such decisions may be relevant. Not only do they not address explicitly the equity dimension, but also they do not even provide the information that decision-makers would need to make a judgement on the desirability of alternative allocations.
