This article argues the case for a policy of "anchored flexibility" in the form of a flexible fiscal rule that allows for the pursuit of economic stability but always anchors that pursuit in fiscal sustainability. The rule is explicitly structured to be simple and is designed in analogy to the inflation-targeting framework. The article heeds the warning that consistently forecasting the output gap with any degree of precision is quite difficult, if not impossible, and thus proposes a target band for the deficit, instead of point targets for the overall deficit and the structural budget balance. To ensure fiscal sustainability over and above the contribution of the deficit rule, the article also proposes a band for the debt/GDP ratio. This debt rule acts as a negative feedback rule that stipulates the adjustments required in the deficit, should the actual debt/GDP ratio move outside the stipulated band. Since the government needs to change revenue and expenditure in order to change the deficit, the article then explores empirically whether and with how much revenue and expenditure in South Africa changed to maintain fiscal sustainability. More specifically the article explores various models of the fiscal reaction function to illuminate government behaviour in South Africa. These models consider how the deficit, expenditure and different types of revenue reacted to the debt/GDP ratio and the output gap to ensure fiscal sustainability. Lastly, the article considers measures that could enhance the automatic stabilisers, while simultaneously allowing for the maintenance of fiscal sustainability in the medium term.

Is there a Phillips curve relationship present in South Africa and if so, what form does it take? Traditionally the method to establish whether or not there is a relationship between the output gap and the change in inflation is merely to regress the latter on the former. This yields the well-known augmented Phillips curve. However, Gordon has argued that this specification of the Phillips curve produces biased results. Instead, he puts forward and estimates successfully for several industrialised countries his so-called triangular model that tests for hysteresis and inertia in the behaviour of inflation, as well as the impact on inflation of changes in the output level. This paper considers whether or not Gordon's triangle model is applicable to South Africa, i.e. are hysteresis and inertia present in South Africa? In addition, in an attempt to find a better estimation of the output gap, the paper also experiments with alternative ways to estimate the long-run output level, including the standard HP-filter, as well as a production function approach.

Persistently high unemployment in South Africa, especially in the face of improved economic conditions since 1994, begs the question: Does unemployment in South Africa respond to changes in output? Okun's law refers to the inverse relationship that exists between cyclical output and cyclical unemployment. This paper estimates Okun's coefficient for the South African economy, using annual data from 1970-2005. Output and unemployment are decomposed into their trend and cyclical components, using a variety of detrending methods. The presence of structural breaks in Okun's relationship is also investigated, while cointegration analysis was also considered. Evidence of a statistically significant relationship between cyclical output and cyclical unemployment are found in both symmetric (estimates range from - 0.77 to - 0.16) and asymmetric (estimates range from - 0.77 to - 0.18) specifications of Okun's law, irrespective of the detrending technique. However, cyclical unemployment constitutes only a relatively small fraction of total (observed) unemployment, which implies that a more expansionary macroeconomic policy stance might only have a limited impact on total unemployment in South Africa.

The size of South Africa's fiscal stimuli, whether intended or not, has helped to avert negative consequences of the global financial downturn. With the economic cycle turning again, consolidation of deficits and a reduction of the level of debt are again the focus of policymakers. These outcomes are generally achieved by either increasing tax rates or cutting spending (discretionary fiscal policy), whereas an alternative option is to allow automatic stabilisers to consolidate budgets. This study attempts to answer whether cyclical factors or discretionary policy minimise output volatility and which one of the two presents a better policy option regarding uncertainty in real economic recovery. For this purpose, a small open‐economy gap model is built using South African data, where the budget deficit is endogenised by way of a fiscal policy “rule.” Sensitivity analyses and robustness checks are carried out using a structural vector autoregression. Given the estimates of both the automatic stabilisers as well as the components of discretionary fiscal policy, we are able to obtain impact multipliers on output and conduct scenario testing for optimal fiscal policy response towards fiscal consolidation as well as debt sustainability.
