International Commodity Prices Transmission to Consumer Prices in Africa

Overview & Synopsis

Global commodity prices spikes can have strong macroeconomic effects, particularly in developing countries. This paper estimates the global commodity prices pass-through to consumer price inflation in Africa. Our sample includes monthly data for 48 countries over the period 2002m02-2021m04. We consider 17 commodity prices separately to take into account both the heterogeneity in price variations and the cross-correlations between them, and to depart from aggregate indices that use weights unrepresentative of consumption in African countries. Using local projections in a panel dataset, we find a maximum passthrough of 24%, and a long-run pass-through of about 20%, higher than usually found in the literature. We also consider country-specific regressions to test whether estimated pass-through are related to countries' observable characteristics.
