Productivity in Services Twenty Years On. A Review of Conceptual and Measurement Issues and a Way Forward

Abstract

Griliches’ seminal contribution on “Output measurement in the service sectors” (1992) is now more than twenty years old. The aim of this paper is to review and systematise the scholarship that has been produced since, to identify any step forward in the conceptualisation of service output, the measurement of service productivity and the account of technical change in affecting productivity in services that might have occurred. An agenda for both innovation and service scholars is proposed.
