Road Infrastructural Investments and Economic Growth in Cameroon

The main objective of this study is to examine the effects of road infrastructural investments on economic growth in Cameroonian fact, the theoretical and empirical literature highlights an ambivalent relationship between government expenditure and economic growth without focusing on transport infrastructure. This study lays a particular emphasis on transport infrastructures. At the level of the methodology, an autoregressive distributed lag model is applied to variables integrated of order 0 and 1. After preliminary tests aimed at avoiding spurious regression, we estimate the parameters of the model usingOLS. We find a negative and significant effect of road infrastructural investments on economic growth. This is explained by the degraded state roads which negatively affect economic growth. However, in the long run, the road infrastructures have a positive and significant effect on economic growth.
