TRANSCRIBER'S NOTE: Italic text is denoted by _underscores_ and bold text by =equal signs=. MANUAL OF REFERENCES AND EXERCISES IN ECONOMICS FOR USE WITH VOLUME II. MODERN ECONOMIC PROBLEMS BY FRANK A. FETTER, PH.D., LL.D. PROFESSOR OF ECONOMICS, PRINCETON UNIVERSITY [Illustration] NEW YORK THE CENTURY CO. 1917 FOREWORD This Manual follows the lines of the "Manual of References and Exercises," published in the autumn of 1916, to accompany the volume on Economic Principles. The literature of the field treated in "Modern Economic Problems" is now so vast that no more than a few of the titles could be included in the following lists. The references given are usually the more recent of those that would be helpful to students desiring to go more deeply into the subjects. The collection of questions and exercises is based upon the list printed, first in 1904 and much enlarged in 1910, in the author's "Principles of Economics." Much material has been added that had been shaped and used in class work at Princeton University, and a few other problems have been drawn from, or suggested by, other published lists. The plan of indicating the original sources of a number of these questions has been found to be too difficult to be completed for the present edition. Indeed, it appears that numerous test problems have become a common heritage for economic teachers, and one can hardly be sure when one has traced the ideas to their original sources. Some of them have appeared in somewhat differing forms in various lists for a half century past. Particular acknowledgment is made to my colleagues, Professors Adriance and McCabe, who devised a number of the questions for class use; and to Dr. Stanley E. Howard, who has given most valuable aid in the preparation of this Manual in its present form. F. A. F. Princeton, N. J., February, 1917.
