Fourth edition, fifth printing. Large 8vo. xxxi, [1], 837, [3] pp. Original blue cloth, spine lettered in gilt, dust jacket (spotting to top edge, just a hint of faint foxing to endpapers, contents otherwise clean and unmarked; jacket price clipped with minor shelf to extremities, notwithstanding a near fine copy). London, Macmillan, 1950.
An unusually nice example of this later reprint of Pigou magnum opus which ‘virtually created the subject of welfare economics’ (ODNB).
