Abstract:
In addition to the conventional linear cointegration test, this paper tests the asymmetry relationship between revenue and expenditure i.e. making a distinction between the adjustment of positive (budget surplus) and negative (budget deficit) deviations from equilibrium using quarterly data on South Africa. The paper reveals that government authorities in South Africa are more likely to react faster when the budget is in deficit than when in surplus and that the stabilisation measures by government are fairly neutral at low deficit levels, that is, at quarterly deficit levels of 4% of GDP and below. We conclude that the attempt to achieve fiscal sustainability via a reduction in expenditure on sectors conducive to economic growth might be prone to social and politically shocks which could render such fiscal policy unsustainable. In South Africa the main fiscal challenge, therefore, is to find ways through which the recent gains in fiscal solvency can be consolidated. The increasing tension amongst local communities complaining about poor service delivery by the government could be a recipe for fiscal unsustainability.
