2 ECONOMIC ESSAYS IN HONOR OF JOHN BATES CLARK a a Ly Le with Clark is organic relation rather than objective coincidence. In 1876 Dunbar had admitted, “The United States have thus far done nothing toward developing the theory of political economy,” and four years later Cliffe Leslie had particularized: “American political economy is in the main an importation from Europe, not an original development.” But the extraordinary changes in American economic organization were already begin- ning to exert influence. A new spirit of realistic study of sur- rounding phenomena was becoming manifest, with an accompany- ing reflex of doctrinal controversies then raging among English economists. More notable than these factors was the return to the United States in the early eighties of a remarkable company of young scholars from post-graduate study in German universities. Their arrival and activity effected a virtual renascence in American economic thought. With others trained in this country lodgment was found in leading universities; student bodies gathered, and productive scholarship developed. The dominant characteristics of the group were an avowal of the historical inductive method, and an election in the main of concrete problems for inquiry. At Harvard, Taussig traced the growth and influence of American protectionism; at Yale, Hadley concerned himself with railway transportation, and Farnam with social problems; at Columbia, Seligman studied the theory and practice of public finance and Mayo-Smith pursued statistical inquiries; at Johns Hopkins, Ely made pioneer studies of local taxation and of the labor movement; at Pennsylvania, James studied municipal economics and at Michigan, H.
