British economist ALFRED MARSHALL (1842-1924) was one of the most prominent thinkers of his age on the philosophy of finance, and his groundbreaking Principles of Economics (1890) was for years the standard text on the subject. Here, in Elements of Economics of Industry, he adapts his classic text for students. First published in 1892, it still serves as an excellent primer on such topics as: . economics as part of the study of humanity . the development of economic laws from the beginning of civilization . how capital yields income . how consumer demand creates markets . land, labor, capital, and organization as agents of production . the balance of supply and demand . the interplay of labor and earnings . the impact of trade unions . and much more.
