Tax base variability and procyclical fiscal policy in developing countries

Based on a sample of 56 countries, we show that fiscal policy in the G7 countries appears to be acyclical while fiscal policy in developing countries is procyclical (i.e., fiscal policy is expansionary in good times and contractionary in bad times). To explain this puzzle, we develop an optimal fiscal policy model in which running budget surpluses is costly because they create pressures to increase public spending. Given this distortion, a government that faces large fluctuations in the tax base-as is the case for developing countries-will find it optimal to run a procyclical fiscal policy.
