Estimation of Labour Productivity at Industry Level – Theoretical Aspects and Practical Application

The article presents a methodology for constructing an indicator for the estimation of labour productivity and its changes at industry level. It discuses the practical necessity of such an indicator as well as the characteristics it should possess in order to reflect as accurately as possible the performance of labour productivity in static and dynamic terms. Different alternatives are reviewed and the choice of certain statistical data and procedures on which to construct the desired measure is argued. The choice is based on theoretical considerations and the practical possibilities of the public information available at the moment in Bulgaria provided by the National Statistical Institute (NSI).
