The Best of the OLL No. 23: Abbé de Condillac, “On Value and Trade” (1776)

This is part of “The Best of the Online Library of Liberty” a collection of classroom-friendly excerpts from some of the most important material in the OLL. This extract consists of two chapters from Condillac’s book *[Commerce and Government](* (1776) in which he promotes a radically new and different subjective theory of value which has some striking similarities to that put forward by the Austrian economists during the Marginal Revolution of the 1870s.
