Note.—Although most texts still present the older, narrow conception of land rent, its defects have been revealed by many critics. J. B. Clark has been the chief champion of the broader conception; American Economic Association, 1st ser., Vol. III, No. 2, Capital and Its Earnings (1888); and Distribution of Wealth, ch. IX and ch. XIII. See our summary of the present situation, American Economic Association, 3d ser., Vol. II, p. 241 (1900). Alfred Marshall's effort to save the older conception by compromise on a "quasi-rent" doctrine has many supporters, but this doctrine is examined in detail and criticized adversely by the writer in an article entitled "The Passing of the Old Rent Concept," Quarterly Journal of Economics, Vol. XV, pp. 416-455 (1901). For both negative and positive reasons for a change in the concept, see The Relations between Rent and Interest, before cited (in note to ch. 8).
