A medium-sized, open-economy, fiscal DSGE model of South Africa

Much of the research on fiscal multipliers has used reduced form modelling approaches. While these models have been extended to include richer controls and identification approaches, it remains unclear whether shocks identified capture the true structural shocks. An alternative way to identify these shocks is through dynamic stochastic general equilibrium models. This paper estimates an open-economy dynamic stochastic general equilibrium model for South Africa, but with a more detailed fiscal block, to measure the impact of fiscal policy shocks on macroeconomic outcomes.
