Abstract
The Granger-causality between renewable energy consumption and economic growth in Zimbabwe is empirically examined using the 1990-2019 time-series data. The study is motivated by the lack of empirical evidence on which variable drives the other in Zimbabwe – between renewable energy consumption and economic growth; and by the need to provide informed guidance to policy makers on whether the country’s drive towards cleaner sources of energy in combating global warming have spill over causal effects on economic growth. In an effort to address omitted-variable bias, the study used the autoregressive distributed lag bounds testing approach within a multivariate Granger-causality model. The results of the study confirm the presence of a Granger-causal relationship between renewable energy consumption and economic growth in Zimbabwe. However, this relationship is found to be time variant. While the results reveal the presence of bidirectional Granger-causality between renewable energy consumption and economic growth in the short run, in the long run, unidirectional Granger-causality from renewable energy consumption to economic growth is confirmed. These results establish that in Zimbabwe, energy conservation policies are detrimental to the national economic growth efforts. Policy makers are, therefore, recommended to draft pro-renewable energy policies as the outcome of such is not only reduced carbon footprint but also real sector stimulation. Energie rinnovabili e crescita economica in Zimbabwe: una prospettiva causale In questo articolo viene esaminata empiricamente la causalità tra energie rinnovabili e crescita economica in Zimbabwe utilizzando il test di Granger relativamente al periodo 1990-2019. Lo studio è motivato dalla mancanza di evidenze empiriche circa la relazione tra queste due variabili in Zimbabwe e dalla necessità di capire se guidare il paese verso fonti più pulite di energia per combattere il riscaldamento globale può avere effetti causali di spill-over sulla crescita. Nel tentativo di ottemperare al problema delle variabili omesse, questo studio ha utilizzato il test autoregressivo ad intervalli distribuiti all’interno di un modello di Granger-causalità multivariato. I risultati confermano la presenza di una relazione di Granger-causalità tra energie rinnovabili e crescita economica in Zimbabwe. Tuttavia, questa relazione sembra essere variabile nel tempo: i risultati rivelano la presenza di Granger-causalità bidirezionale tra queste due variabili nel breve periodo, mentre nel lungo periodo la Granger-causalità risulta essere unidirezionale. Si raccomanda pertanto ai governi di progettare politiche che sviluppano le energie rinnovabili, in quanto in questo modo non si ottiene soltanto una riduzione delle immissioni di carbonio ma anche una stimolazione della crescita economica.
