Modeling African Economies

This chapter presents a stylized framework for modeling African economies using the dynamic stochastic general equilibrium (DSGE) approach. We introduce several features relevant to low-income countries, including a large population without access to financial markets, restricted international capital mobility, low governance quality, and explicit central bank balance-sheet effects. The calibrated model can be useful in addressing important macroeconomic policy issues in many African economies. The applications presented here include (i) reserve accumulation policy responses to aid surges, (ii) government spending, financing schemes, and fiscal multipliers, (iii) management of natural resource revenues, and (iv) public investment surges and debt sustainability.
