The Malmquist and Hicks-Moorsteen productivity indexes are the two most widely used theoretical indexes for measuring productivity growth. Since these productivity indexes are defined by unknown distance functions, it is necessary to estimate the distance functions to compute them in principle. On the other hand, the ToÌˆrnqvist productivity index is an empirical index number formula that is directly computable from the prices and quantities of the inputs and outputs alone. Caves, Christensen, and Diewert (1982) (CCD) imply that the Malmquist index coincides with the ToÌˆrnqvist index, under profit maximising behaviour and constant returns to scale technology. The purpose of the present paper is to point out that the Hicks-Moorsteen productivity index coincides with the ToÌˆrnqvist productivity index under the same condition. We emphasize that the condition of constant returns to scale is indispensable for deriving the equivalence between two indexes. Moreover, even when this condition is relaxed to the ð ›¼ returns to scale, the equivalence between the Hicks-Moorsteen and ToÌˆrnqvist productivity indexes is shown to hold true.
