The productivity of intangible factors of production: Some measurement issues applied to Swedish management consulting firms

Abstract

This study addresses issues related to the productivity measurement of firms using intangible input to produce intangible output. It examines the difficulties associated with the productivity measurement of such firms and suggests a measure that takes account of the unique attributes of the factors used in their production. This issue is examined with application to a professional service industry-management consulting-in which all inputs and outputs are intangibles. © 1999 Sage Publications, Inc.
