The perception that inflation dynamics in Sub-Saharan Africa (SSA) are driven by supply shocks implies a limited role for monetary policy in influencing inflation in the short run. SSA's rapid growth, its integration with the global economy, changes in the policy frameworks, among others, in the last decade suggest that the drivers of inflation may have changed. We quantitatively analyze inflation dynamics in SSA using a Global VAR model, which incorporates trade and financial linkages among economies, as well as the role of regional and global demand and inflationary spillovers. We find that in the past 25 years, the main drivers of inflation have been domestic supply shocks and shocks to exchange rate and monetary variables; but that, in recent years, the contribution of these shocks to inflation has fallen. Domestic demand pressures as well as global shocks, and particularly shocks to output, however, have played a larger role in driving inflation over the last decade. We also show that country characteristics matter-the extent of oil and food imports, vulnerability to weather shocks, economic importance of agriculture, trade openness and policy regime, among others, help in explaining the role of shocks.

This paper estimates the effects of exogenous changes in income and consumption taxes. The tax shocks are proxied with a narrative account of tax liability changes in the United Kingdom. Income tax cuts have large effects on GDP, private consumption, and investment. The effects of consumption tax cuts are modest and not statistically significant on GDP and its components. Shifting the burden of taxation from income to consumption is expansionary. Consistent with conventional public finance theories, these results indicate that it is crucial to distinguish between direct and indirect taxation when studying the transmission mechanism of fiscal policy.
