Total factor productivity growth, technological progress and technical efficiency changes: Productivity change dimensions in Tunisia

  • Maha HELALI KALAI Faculty of Economics and Management of Sfax. University of Sfax.
Keywords: total factor productivity, technical efficiency, technological progress, stochastic frontier approach, Tunisian economy



In this study, we use the stochastic frontier production approach so as to split the total productivity growth sources into technical progress and technical efficiency changes of the economic sectors in Tunisia between 1961 and 2014. Based on sectors evolution, the analysis is centred on the technological progress trend, the technical efficiency change and the role of productivity change in economic growth. The empirical results show that the production factors have a significant effect on productivity. The review of the total factor productivity growth sources reveals that the contribution of technological progress is the main source of this growth.
