Investment in Africa's manufacturing sector: A four country panel data analysis

Firm-level data for the manufacturing sector in Africa, presented in this paper, shows very low levels of investment. A positive effect from profits onto investment is identified in a flexible accelerator specification of the investment function controlling for firm fixed effects. There is evidence that this effect is confined to smaller firms. A comparison with other studies shows that, for such firms, the profit effect is much smaller in Africa than in other countries. Reasons for the relative insensitivity of investment to profits in African firms are suggested.
