The aim of this article is to assess the empirical evidence of the nexus between GDP and energy consumption for Italy during the period 1970-2009, using a time-series approach. After a brief introduction, a survey of the economic literature on this issue is shown, before discussing the data and introducing some econometric techniques. Stationarity tests reveal that both series are non-stationary, or I(1). Moreover, a cointegration relationship is found between the two variables. The short-run dynamics of the variables show that the flow of causality runs from en-ergy use to GDP, and there is a long-run bidirectional causal relationship (or feedback effect) between the two series. Consequently, we conclude that energy is a limiting factor to GDP growth in Italy, and that energy conservation policy should be formulated and implemented wisely.

Abstract
The aim of this article is to assess the empirical evidence of the nexus between GDP and energy consumption for Italy during the period 1970-2009, using a time-series approach. After a brief introduction, a survey of the economic literature on this issue is shown, before discussing the data and introducing some econometric techniques. Stationarity tests reveal that both series are non-stationary, or I(1). Moreover, a cointegration relationship is found between the two variables. The short-run dynamics of the variables show that the flow of causality runs from en-ergy use to GDP, and there is a long-run bidirectional causal relationship (or feedback effect) between the two series. Consequently, we conclude that energy is a limiting factor to GDP growth in Italy, and that energy conservation policy should be formulated and implemented wisely.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
