Stiglitz [121 has examined the value of information under heterogeneous beliefs. Using results from the theory of screening, he concludes that the private returns to the provision of information do not, in general, correspond to the social returns. He suggests that there is likely to be excessive spending on âhierarchical inf~rmationâ~ and too little spending on âmatching inf~rmation.ââ~ Marshall [8] has briefly considered the situation in which individualsâ beliefs are heterogeneous.
