Benvenuti nell'Anagrafe della Ricerca d'Ateneo
La valutazione delle attività di ricerca che si svolgono nelle università ha assunto un'importanza rilevante sia per l'intero sistema universitario sia all'interno di ogni singolo ateneo. Roma Tre si è quindi dotata di idonei strumenti informativi in grado di supportare al meglio le azioni di monitoraggio e di valutazione delle attività di ricerca svolte nei propri dipartimentied ha realizzato una Anagrafe della Ricerca di Ateneo.
EnglishWe empirically analyze the nexus between GDP and energy consumption in the 1970-2009 years for Italy, using a time-series approach. After a brief introduction, we pre-sent the discussion of the data. Stationarity tests reveal that both series are non-stationary, or I(1). Moreover, since both series show the presence of a structural break, a Gregory and Hansen cointegration test has been per-formed. The results evidence the presence of a long-run relationship. Causality tests re-veal that the “neutrality hypothesis” emerges, insomuch as the absence of a causal rela-tionship be-tween energy consumption and real GDP is discovered. The IRFs analysis evidences that a shock to the energy consumption affects GDP for one period, but dies out very quickly. While shocks to GDP create a smaller but significant response in the energy consumption, although it falls to zero in few periods. Finally, we calculate with an ECM that the long-run multiplier is 0.70. The energy consumption will increase to correct the disequilibrium, with 11% of the (remaining) deviation corrected in each sub-sequent time period. In addition, a one-unit increase in the GDP immediately produces a 1.07 unit increase in the energy consumption.

| Abstract: | We empirically analyze the nexus between GDP and energy consumption in the 1970-2009 years for Italy, using a time-series approach. After a brief introduction, we pre-sent the discussion of the data. Stationarity tests reveal that both series are non-stationary, or I(1). Moreover, since both series show the presence of a structural break, a Gregory and Hansen cointegration test has been per-formed. The results evidence the presence of a long-run relationship. Causality tests re-veal that the “neutrality hypothesis” emerges, insomuch as the absence of a causal rela-tionship be-tween energy consumption and real GDP is discovered. The IRFs analysis evidences that a shock to the energy consumption affects GDP for one period, but dies out very quickly. While shocks to GDP create a smaller but significant response in the energy consumption, although it falls to zero in few periods. Finally, we calculate with an ECM that the long-run multiplier is 0.70. The energy consumption will increase to correct the disequilibrium, with 11% of the (remaining) deviation corrected in each sub-sequent time period. In addition, a one-unit increase in the GDP immediately produces a 1.07 unit increase in the energy consumption. |
