討論提要

This paper reexamines the welfare implications in three pricing regimes (mill, uniform and discriminatory) for a monopoly in a stochastic environment. It considers a risk averse monopolist faces two markets with stochastic and linear demands. The monopolist is assumed to commit to an irreversible price in each market before the uncertainty is removed. Several unconventional results are shown to be triggered by the presence of demand uncertainty.

結論

i)                    the equivalence of expected output under the three pricing regimes is invalid unless the two markets are identically risky;

ii)                   the equivalence of expected utility of profits under mill and uniform pricing does not hold except that the distances between the firm’s plant location and the two markets are the same; and

iii)                 uniform pricing could outperform the other two in terms of consumers’ surplus and social welfare if the markets are not equally volatile.

Extension

Can be extend to duopoly, three-dimension space. The technology of stochastic environment can be applied to taxation issue.
