Productivity trends in public sector enterprises

Abstract

This paper presents results of the second part of the study on Productivity in Public Sector Enterprises (PSEs). The aim is to determine trends of productivity in PSEs. The study period covers the years 1965-66 to 1976-77. It also reflects the period since the inception of BPE. Several hypotheses are tested concerning productivity trends within specific industry groups and between industry groups. The statistical model considered most appropriate for the trend analysis is the "Analysis of Covariance (ANACOVA)' model. Method of Linear Contrasts is used for hypothesis testing concerning differences between mean productivities.
