How does monetary policy affect the poor? Evidence from the West African Economic and Monetary Union

The West African Economic and Monetary Union (UEMOA) has a history of monetary stability and low inflation. Nevertheless, there is substantial variation in relative prices within some UEMOA countries in particular in the price of food relative to other elements of the retail price index (IHPC). Using monthly time-series data for cities within the region, we analyse the impact of changes in monetary policy instruments on the relative Prices of components of the IHPC. We are then able to explore how the burden of monetary policy innovations is likely to be shared between the rich and poor.
