Monetary and Fiscal Policy in the Presence of Informal Labour Markets: A DSGE Approach

Omobola Adu, Philip Alege, Oluranti Olurinola


In this paper, we investigate the transmission mechanism of monetary and fiscal policy shocks on inflation and output in the presence of an informal economy in Nigeria. To achieve this, a New Keynesian Dynamic Stochastic General Equilibrium (DSGE) model is modified to include informality in the labour and product market. The model is estimated using the Bayesian technique and the findings shows that in the case of a monetary policy shock, formal output tends to decline, while there is an expansion in informal output, at least in the short-run. The results also reveal that a fiscal policy shock brings about an initial decline in informal output. Hence, it is imperative for policymakers to strive to formalise the informal sector in order to ensure the effectiveness of monetary policy.
