Corruption and growth in Africa

•Analyse direct and indirect corruption influence on economic growth in Africa•Analyse how corruption interacts with the components of government expenditure•Find that corruption makes the negative impact of military spending larger•Find that these effects are robust to alternative measures of corruption

A major concern in the development of African economies is the impact of corruption on economic growth and while there is general agreement on its detrimental effects, there is considerable debate over its nature and importance. In particular there is little work on the interaction between corruption, government expenditures and how this influences economic growth in countries in the region. This paper takes an endogenous growth model, extends it to include different categories of government spending and then introduces the possibility of corruption, which is allowed to have different effects on each of the categories. The results confirm the negative effect of corruption and military spending, but also show that corruption interacts with military burden, through indirect and complementary effects, to further increase its negative effect. The policy implications are that the effects of corruption on economic growth are worse than was thought in countries which have high military burdens.
