JEVONS, WILLIAM STANLEY. A Serious Fall in the Value of Gold Ascertained, and Its Social Effects Set Forth. 2 lithographed charts; folding table. 8vo, original flexible cloth with front-cover label. London, 1863 E1000-2000 FIRST EDITION OF JEVONS'S FIRST BOOK, an examination of the fall in the value of gold since the Australian andCalifornian discoveries of 1849. "He determined to investigate this long-run change . . . and to disentangle it from other factors affecting that price level. The outcome was . . . a piece of work which established new standards of sophistication for applied economic research . . . Jevons had virtually to invent the concept ofa price index for himself, as he also did a means of comparing changes in its value over time, a task which he accomplished with astonishing competence and originality"-New Palgrave II, 1011.
