reassessing the export-led growth relationshipthrough cointegration methods

The purpose of this study was to assess the applicability of the export-led growthnexus in the context of Namibia for the period 1990 to 2013 through theapplication of the Vector Autoregression (VAR) technique, which incorporatesthe following processes: Unit root tests, determination of the optimal lag length,testing the stability of the vector autoregression system, cointegration tests,estimation of the long-run equation, diagnostic checks for serial correlation,heteroscedasticity and normality, as well as the pairwise Granger-causality tests.Quarterly time series datasets were engaged.The study found cointegratingrelationships among the variables that were examined. Further, the study foundthat export is a good predictor of economic growth. Therefore, the need forNamibiato pay special attention to developments in the export sector ofitseconomycannot be overstated. Additional research opportunities for upcomingresearchers to further probe the issue under consideration are suggested.
