Abstract: 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 pass-through of 24%, and a long-run (18 months) pass-through of about 20%, higher than usually found in the literature, which typically uses aggregate indices. We also consider country-specific regressions to test whether estimated pass-through are related to countries observable characteristics. We find evidence that the pass-through is negatively correlated with the GDP per capita and the quality of transport infrastructure, and positively correlated with the share of food and energy in the consumption basket and the share of taxes on goods and services in government revenue. Net oil exporters, countries with larger energy subsidies and with a more independent central bank tend to have a lower pass-through. We further show that commodity-specific pass-through are correlated with the share of corresponding goods in the consumer basket.
