This paper measures the extent to which South African economic growth is an engine of growth in sub-Saharan Africa. Results based on panel data estimation for 47 African countries over four decades suggest that South African growth has a substantial positive impact on growth in the rest of Africa, even after controlling for other growth determinants. The estimates are robust to the effects of global and regional shocks, changes in model specification, and sample period.

This paper analyzes the implications of devaluation and a variety of structural disturbances in a dual exchange rate economy. A key feature of the model developed is its explicit recognition of both private (fraudulent) and officially-sanctioned cross transactions between the two exchange markets. The principal lesson to be learned from the analysis is that popular notions as to the effects of devaluation or of other disturbances are to be viewed with considerable caution when the dual rate regime involves inter-market transactions.
