N2 - The Luenberger productivity index can simultaneously contract inputs and expand outputs, and is dual to profit maximization. The index is a generalization of the Malmquist productivity index, which is commonly used in productivity studies. Both the Luenberger and Malmquist productivity indices are applied to the prefectural level data in Japan over 1955-1995. If profit maximization assumption is more appropriate than revenue maximization, Malmquist productivity index overestimates productivity changes, since it provides nearly twice growth rate compared to the rate given by the Luenberger productivity index.
