ABSTRACT
Joseph Stiglitz responded by saying that the health care sector was more problematic in those respects than the education sector, but the general point that one could get information from the choices individuals made was clear, and trying to generate institutions that reflected this idea was important. The problem was pervasive in the health care sector, said Stiglitz, and could not be avoided, but similar issues also arose in one way or another in other social sectors, even education. Stiglitz responded by pointing out that the fungibility of funds was, in a sense, different from the issue under discussion: evaluating a particular delivery system. Stiglitz replied population projects were valuable to the extent that they could be replicated on a larger scale. Whether they should or should not be replicated depended on whether they were working, which was why evaluation needed to be part of what the World Bank calls the knowledge bank.
