Abstract
The main objective of the study was to measure the impact of transport infrastructure development on economic growth in Namibia for the period, 1990-2019. The Vector Error Correction Model (VECM) was adopted in achieving the objectives of the study. The annual time series data was sourced from the World Bank Database and the Ministry of Finance. The unit root test was used to determine the order of integration, whilst the Johansen cointegration test was used to test for the existence of the long run relationship.The unit root test revealed that all the variables are integrated of order one. This warranted the estimation of the VECM which requires all the variables to be integrated of the same order. The Johansen cointegration test revealed a long run relationship amongst the variables, as it was confirmed by both the Trace and Maximum Eigen test statistic. The vector error correction provided both short and long run estimates. The findings revealed a negative long run relationship between expenditure on transport and gross domestic product. On the contrary, the short run estimates revealed a positive relationship between expenditure on transport and gross domestic product in Namibia. However, the relationship is statistically insignificant.
