Oil revenues for public investment in Africa: targeting urban or rural areas?

摘要

This paper investigates the effects of oil-financed public investment on economic growth and poverty reduction using a dynamic multi-sectoral general equilibrium model featuring inter-temporal productivity spillovers. The paper shows that the relationship between resource-rent flows and real exchange rates, output growth, and poverty is less straightforward than simple models of the "resource curse" suggest. Taking Ghana as a stylized agriculture-based economy with poverty most pronounced in a region with home based agricultural production, a policy mix of smoothing the real exchange rate shock and an allocation of infrastructure spending in rural areas seems to be the most promising public investment strategy to enhance growth and reduce poverty.
