Abstract

Monetary policy in sub-Sahara Africa (SSA) has undergone an important transformation in recent decades. With the advent of sustained growth and generally stable fiscal policies in much of the region, many countries are now working to modernize their monetary policy frameworks. This book provides a comprehensive view of the many monetary policy issues in sub-Saharan Africa. It reflects an effort to fill a gap in the current literature and collects research by staff of the IMF and other institutions, as well as from policymakers within central banks in SSA. The chapters explore the many dimensions of monetary policy in SSA. This volume will serve as an important reference for academics and policymakers and will inform future policy debates. The book highlights two points, one policy-related and the other methodological. Although these countries differ in important ways from advanced and emerging market countries, the monetary policy issues they face are not fundamentally different from those faced elsewhere. Policy aims to provide an anchor for inflation over the medium term while also responding to external and domestic shocks. Likewise, Sub-Saharan African countries are in the process of modernizing their policy frameworks, by clarifying their objectives and improving their operational frameworks, making policy increasingly forward-looking and improving their forecasting and analytical capacity.

VAR methods suggest that the monetary transmission mechanism may be weak and unreliable in low-income countries (LICs). But are structural VARs identified via short-run restrictions capable of detecting a transmission mechanism when one exists, under research conditions typical of these countries? Using small DSGEs as data-generating processes, we assess the impact on VAR-based inference of short data samples, measurement error, high-frequency supply shocks, and other features of the LIC environment. The impact of these features on finite-sample bias appears to be relatively modest when identification is valid—a strong caveat, especially in LICs. However, many of these features undermine the precision of estimated impulse responses to monetary policy shocks, and cumulatively they suggest that “insignificant” results can be expected even when the underlying transmission mechanism is strong.

This paper examines how susceptible East African Community (EAC) economies are to asymmetric shocks, assesses the value of the exchange rate as a shock absorber for these countries, and reviews adjustment mechanisms that would help ensure a successful experience under a common currency. The report draws on analysis of recent experiences and examines likely future changes in the EAC economies.

We develop a tractable small open-economy model to study the first-round effects of international food price shocks in developing countries. We define first-round effects as changes in headline inflation that, holding core inflation constant, help implement relative price adjustments. The model features three goods (food, a generic traded good and a non-traded good), varying degrees of tradability of the food basket, and alternative international asset market structures (complete and incomplete markets, and financial autarky). First-round effects depend crucially on the asset market structure and the different transmission mechanisms they trigger. Under complete markets, inter-temporal substitution prevails, making the inflationary impact of international food prices proportional to the food share in consumption, which in developing economies is typically large. Under financial autarky, the income channel is dominant, and first-round effects are instead proportional to the country's food balance—the difference between the country's food endowment and its consumption—which in developing countries is typically small. The latter result holds regardless of the degree of food tradability. Incomplete markets yield a combination of the two extremes. Our results cast some doubt on the view that international food price shocks are inherently inflationary in developing countries.

We examine the effects that variations in the international food prices have on democracy and intra-state conflict using panel data for over 120 countries during the period 1970-2007. Our main finding is that in Low Income Countries increases in the international food prices lead to a significant deterioration of democratic institutions and a significant increase in the incidence of anti-government demonstrations, riots, and civil conflict. In the High Income Countries variations in the international food prices have no significant effects on democratic institutions and measures of intra-state conflict. Our empirical results point to a significant externality of variations in international food prices on Low Income Countries' social and political stability.

The Selected Issues paper for Uganda and Rwanda discusses the impact of rising international food and fuel prices on inflation. Unlike in the case of fuel-producing countries, the East African Community countries are major agricultural producers, with agriculture accounting for 20 percent to 40 percent of their GDP. The two most important factors limiting the pass-through of world food commodities are therefore the high degree of self-sufficiency in the production of main tradable food commodities and their relative insulation from international markets.
