This paper deals with the welfare implications of information sharing between Bertrandtype duopolists when there is cost uncertainty. The paper distinguishes itself from the previous work in that it is not restricted to those special cases where goods are physically substitutes or costs are stochastically independent, and in that it carries out a complete analysis of the impact of information pooling on consumers and the society as a whole. In particular, by introducing new concepts such as the variation and allocation effects, we point out the possibility that the exchange of cost information is beneficial to Bertrand firms. Comparison with the more popular Cournot duopoly case is also made.
