This paper suggests that it is essential to save a substantial portion of mineral revenues now to ensure fiscal sustainability for a post-diamond period. Taking the non-mineral primary balance into account can help clarify desirable fiscal policies. Botswana’s real effective exchange rate is broadly in line with economic fundamentals and consistent with external su...

Assuming a social welfare function that smoothes expenditure, this paper calculates a sustainability benchmark for the non-mineral balance in Botswana that is based on a notion of a "permanent income" from non-renewable resources. It is derived by constructing a hypothetical annuity from revenues from these resources, which is held constant in terms of GDP. Botswan...
