Abstract

This paper takes a local perspective on global food price shocks by analyzing food price transmission between regional markets in Ghana. It also assesses the impacts of food price increases on various household groups. Taking the recent global food crisis as an example, we find that prices for domestic staples are highly correlated with prices for imported rice. However, price transmission between pairs of domestic regional markets is limited; it is complete for local rice and maize only when more rigorous cointegration analysis is applied. Our findings also show the important role of seasonality in the determination of market integration and price transmission. The welfare effect for households as consumers appears relatively modest at the aggregate national level due to relatively diverse consumption patterns. However, the national average hides important regional differences, both between regions and within different income groups. We find that the poorest of the poor—particularly the urban poor—are the hardest hit by high food prices. The negative effect of the food crisis is particularly strong in northern Ghana. Different consumption patterns, in which grains account for a larger share of the consumption basket in the north compared to the rest of the country, together with much lower initial per capita income levels, are the main explanations for this regional variation in the price effect.
