Y.—: Commercial Cycles (p. 709)

In England there has been no “commercial crisis” since 1866, though crises have continued to make their appearance in the United States, as e.g. in 1893 and 1907. But the alternations of commercial prosperity and depression continue; and the cyclical movement, as Jevons first showed, seems to occupy about ten years. The study of the subject must begin with Jevons' papers (1875–1882) on the Periodicity of Commercial Crises, printed in his Investigations in Currency and Finance (1884). A guide to the history and literature of the subject will be found in Herkner's article Krisen in Conrad's Handwörterbuch der Staatswissenschaften. The relation between Foreign Trade, Bank Rate, Employment, Marriage Rate, Pauperism, &c., for the period 1856–1907 can be conveniently observed in Table IX, and Chart II, “The Pulse of the Nation,” in Beveridge, Unemployment. On American conditions and their connexion with currency questions, see the papers of Seligman and others in The Currency Problem and the Present Financial Situation (N. Y. 1908).
