The role of infrastructure development in economic growth in Zimbabwe (1981-2008)
Abstract
The current study is aimed at examining the role infrastructure development plays in influencing
economic growth in Zimbabwe using time series data from 1981 to 2008. The study also seeks to
establish the direction of causality between infrastructure development and economic growth.
The study makes use of three infrastructure indicators namely electricity production per capita,
telephone mainlines density and energy consumption per capita to capture the effects of
infrastructure development on economic growth. The study employed the VAR approach to
examine the impact of infrastructure development on economic growth. The study findings
revealed that infrastructure development as measured by all three indicators has positive effect
on economic growth in the short run. In the long run, the study results were mixed with
electricity production and energy consumption indicators having positive effects and telephone
mainlines density exhibiting negative effect. The granger causality test revealed that past values
of telephone mainlines density and energy consumption have an effect on future economic
growth performance, while electricity production does not
