Transport Infrastructure Investment and Transport Sector Productivity on Economic Growth in South Africa (1975-2011)

Abstract

This paper examines the impact of transport infrastructure investment and transport sector productivity on South African economic growth for the period 1975-2011. We use a Vector Error Correction Model and a Bayesian Vector Autoregressive model as empirical tools. The models provide an insight into the dynamic shocks on economic growth through impulse responses. The VECM reveals that economic growth is influenced by inflation, domestic fixed transport investments, and real exchange rate, yet on the BVAR model it was influenced by inflation, domestic fixed transport investments, multi factor productivity, real exchange rate and second period Gross Domestic Product
