Fiscal policy in times of fiscal stress (or what to do when r > g)

Abstract
South Africa runs a primary fiscal deficit and the long-term interest rate on government borrowing, r, is greater than the long-term economic growth rate, g. Without intervention, debt will continue to rise until there is a disorderly fiscal stop. Reforms to raise growth have not materialised, leaving fiscal consolidation as the second-best solution. Using a medium-sized, open-economy, fiscal DSGE model of South Africa, we show that the least cost policy is to impose a time-consistent fiscal policy rule with debt-to-GDP as the fiscal anchor and a pre-announced path for government consumption spending as the intermediate operational objective. This result obtains with and without explicit policy coordination between the fiscal and monetary authorities.
