Abstract

In recent years the Malmquist index has gained in popularity as a measure of productivity change. We demonstrate that, in the presence of non-constant returns to scale, the Malmquist productivity index does not accurately measure productivity change. The bias is systematic, and depends on the magnitude of scale economies. © 1995.
