Changes in output per worker in a group of 32 manufac-turing industries are analyzed in some detail. The change in output per worker (and also in output per man-hour) ap-pears to be very erratic during short periods—ranging from —3.2 percent per year (in 1931-33) to 5.4 percent per year (in 1937-39) within a single decade--despite the relative
