Income and Substitution Effects for Mean-Preserving Spreads
精确界定了Sandmo提出的均值保持展形中替代效应所需的补偿方法，并应用于产出价格不确定下竞争性企业的模型。
A. Sandmo has ascribed the indeterminancy of the comparative static result for a mean-preserving spread to the presence of both an income and a substitution effect. In this note, the compensation method needed to isolate the substitution effect identified by Sandmo is made precise. The compensation method is derived from a model that is sufficiently general to include many important applications of the theory of uncertainty. The method is used to identify the substitution effect in Sandmo's model of the competitive firm under output price uncertainty.
