ABSTRACT
§1. It has already been remarked 1 that, up to 1911, no systematic treatise on economic principles had contained any attempt to answer, comprehensively and directly, the question: What are the causes of inequality of individual incomes?; that in that year Professor Taussig published the first edition of his Principles of Economics, in which he devoted one chapter out of seventy to Inequality and its Causes; and that since that date there is no great progress to record in the treatment by economists of this part of what Ricardo called “the principal problem of political economy,” the solution of which was sketched in outline by Professor Cannan in 1905 in his classical article, The Division of Income.
