In this paper, we analyze how lack of credibility and transparency of monetary and fiscal policies undermines the effectiveness of macroeconomic policies to isolate the economy from commodity price fluctuations. We develop a general equilibrium model for a commodity-exporting economy where macro...

In recent years, many Low-Income Countries (LICs) have implemented substantial reforms to their monetary policy frameworks, but existing economic research has not provided a clear rationale to guide those efforts. In this paper we analyze the role of monetary policy frameworks in the propagation...

We compare business cycle fluctuations in Sub-Saharan African (SSA) countries vis-à-vis the rest of the world. Our main results are as follows: (i) African economies stand out by their macroeconomic volatility, which is is reflected in the volatility of output and other macro variables; (ii)...

The experience of developing countries over 1990-2010 indicates that commodity prices have a significant impact on fiscal outcomes. Both revenue and expenditure rise in response to commodity (import or export) price increases; the response of the fiscal deficit is ambiguous. A floating exchange...

This paper documents the determinants of real oil price in the global market based on SVAR model embedding transitory and permanent shocks on oil demand and supply as well as speculative disturbances. We find evidence of significant differences in the propagation mechanisms of transitory versus...

This paper studies whether fiscal policy plays a stabilizing role in the context of import food price shocks. More precisely, the paper assesses whether fiscal policy dampens the adverse effect of import food price shocks on household consumption. Based on a panel of 70 low and middle-income...

This paper investigates the impact of commodity price shocks on financial sector fragility. Using a large sample of 71 commodity exporters among emerging and developing economies, it shows that negative shocks to commodity prices tend to weaken the financial sector, with larger shocks having...

This paper focuses on identifying potential asymmetric responses of non-commodity output growth in times of positive and negative commodity terms-of-trade shocks. Using a sample of 27 oil-exporting countries and a panel VAR method, the study finds: 1) the short-and medium-run response of real...
