Abstract

This article examines whether the consumption-income ratio is stationary in 50 African countries. We use the residual augmented least squares (RALS-LM) unit root test that allows for structural breaks. The empirical evidence shows that the consumption income ratio is stationary around structural breaks in most (44 out of 50) African countries. This is consistent with the predictions of most economic theories. The general finding of mean reversion implies that (policy) shocks are likely to have only temporary effects on the consumption-income ratio in most African countries .
