Firm level data for the manufacturing sector in Africa, presented in this p
aper, shows very low levels of investment. The importance of profit effects
on in vestment is investigated using a flexible accelerator, a specificati
on based on the Euler equation and a simple generalisation of these specifi
ciations. There are controls for firm fixed effects. It is shown that the p
rofit effect is very similar for both the accelerator and Euler equation sp
ecifications. A comparison with other studies shows that, for small firms,
the effect is much smaller in Africa than for other countries. Reasons for
the relative insensitivity of investment to profits in African firms are su
ggested. For the most general specification tested there are no significant
differences in the size of the profit effect across the four countries in
the study.
