This paper empirically investigates the macroeconomic responses to commodity price shocks with a focus on fiscal variables in a sample of thirty-three African commodity-dependent countries. Using the heterogeneous panel structural vector autoregressive (SVAR) approach developed by Pedroni, we find that government revenues as well as government expenditures react to commodity export prices shock. However, there is a large degree of heterogeneity across countries. Following country characteristics, we find that the response of fiscal variables is higher for countries dependent on extractive commodities than those dependent on agricultural ones. We also highlight the benefits of flexible exchange rate regimes for accommodating external shocks and ensuring macroeconomic stability, which in turn is beneficial to government revenue mobilization. Our results suggest that the African government should seize commodities as an opportunity and increase their efforts in revenue mobilization during price booms and make a productive investment to isolate their finances from commodity price collapses.

The article assesses the potential economic implications of tariff elimination and trade facilitation (TF) in the context of the African Continental Free Trade Area (AfCFTA) agreement for East Africa. Using the most recent GTAP database and computable general equilibrium model, the article provides additional evidence on the socio-economic benefits of the ongoing trade integration process. The results show that the elimination of tariffs would improve economic dynamism in most sectors of activity and household consumption. However, the elimination of tariffs alone would not be sufficient to achieve a significant level of trade integration. From a policy perspective, although a gradual implementation of tariff elimination is more beneficial for the zone, the results highlight the relevance of combining tariff elimination with complementary TF reforms. These reforms amplify the socio-economic gain from the AfCFTA. JEL Codes: F13, F14, F15, E23, C68
