James Mill on Comparative Advantage and the Gains from Trade:

Excerpts from the Elements

James Mill (1773-1836) was a major figure in classical political economy; for biographical data and internet resources see Gonçalo L. Fonseca and Leanne J. Ussher’s New School website. Mill’s Elements of Political Economy was the first textbook of Ricardian economics. John Stuart Mill recalled in his Autobiography  how the book got started:  “My father  … commenced instructing me in the science by a sort of lectures, which he delivered to me in our walks.” The thirteen-year old wrote up the lectures and from his notes grew the book. In the preface James Mill wrote “ My object has been to compose a school-book of Political Economy … I profess to have made no discovery.”

The Elements has a place in the history of classical international trade theory. The first edition (1821) presented with “model clearness” the principle of comparative advantage from chapter 7 of David Ricardo’s Principles of Political Economy and Taxation. Some years later John Stuart Mill was part of a reading group working through the Elements. He recalled in his Autobiography,  “The theory of International Values which I afterwards published, emanated from these conversations.” The theory which appeared as the first of the Essays on Some Unsettled Questions of Political Economy appears to have been a reaction to a mistake in the Elements regarding the evaluation of the gain from trade. In the third and final edition of the Elements James went some way to accommodate his son’s corrections: “I have corrected an error of the former editions.”

Rod Hay’s Documents for the History of Economics website at McMaster makes available the entire 3rd edition of the Elements of Political Economy as well as the other documents mentioned above. However the interest in Mill’s account of comparative advantage justifies reproducing all three (1821, -24 and –26) versions of the comparative advantage section.
