In Pigous Wealth and Welfare, as well as in each of the four editions of his The Economics of Welfare, one chapter is dedicated entirely to the critical assessment, and ultimate rejection, of Paretos law of income distribution. This note highlights Pigous uncorrected misreading of a critical aspect of Paretos analysis of income distribution; illustrates what his criticisms of Paretos law reveal about Pigous objectives for welfare economics; and indicates how Paretos analysis of income distribution could have been criticised in a manner that is consistent with Pigous objectives for welfare economics.
