Is There Any Relationship between Energy and TFP? A Panel Cointegration Approach for Italian Regions

The aim of this work is to examine the long run relationship between total factor productivity (TFP) and energy consumption in Italy from 1996 to 2008 at a regional level. Differently from previous studies, TFP is employed as a measure of economic growth and therefore of technological change. Dynamic Panel estimation technique is used to investigate whether a connection between TFP and energy use exists and its direction. Results show a bidirectional causality for the Italian regions implying that those regions characterized by a higher TFP would invest more in research rather than in energy intensive activities, improving in that way the use of scarce resources and favoring a sustainable growth
