As has been the case for the past five years, the latest (2020) budget paints another sobering picture of South Africa’s public finances and short-term economic outlook. Of particular concern is that this budget does not project that the government debt ratio will stabilise in the medium term (by 2022/23), which means that the current fiscal policy trajectory is unsustainable (which National Treasury acknowledges in the Budget Review). This makes a rating downgrade by Moody’s in March all but inevitable. 

In the budget that was tabled on Wednesday, the budget deficit is projected to be 6,3% in 2019/2020, while increasing to 6,8% the following year, before gradually declining to a still unsustainable 5,7% of the GDP by 2022/23. These large budget deficits contributed to large projected increases in the government debt-to-GDP ratio: this ratio is projected to increase from about 62% in 2019/20 to about 72% by 2022/23. To understand the extent of the deterioration of South Africa’s public finances over the past 12 months, it should be noted that this ratio was projected in the 2019 budget to increase to about 60% by 2022/23.

Burger and Calitz (2020) show that the government debt-to-GDP ratio can be stabilised (and fiscal sustainability can be restored) if: the gap between real interest rates and real GDP growth is reduced, and/or if the primary balance (government revenues minus non-interest government spending) is adequate to avoid an increase in the debt ratio. They then show that the debt ratio has increased over the past decade because the (implied) real interest rate on government debt has increased and the real growth rate has decreased and government ran large primary deficits, at a time when large primary surpluses were required to avoid increases in the debt ratio. 

Between 1998 and 2007, the debt ratio was reduced from just under 50% to just under 30%. This period (especially from 2002 onwards) was characterised by (relatively) high economic growth. Fast economic growth is crucial to stabilising the debt ratio and restoring fiscal sustainability. National Treasury (NT) has proposed structural reforms (aimed at reducing regulatory burdens and backlogs and increasing competitiveness in the economy) to stimulate private sector investment and growth. Given the constraints that continued load shedding will put on South African growth in the near future, as well as projected slower growth in the economies of our main trading partners, and the uncertainties associated with disruptions wrought by the coronavirus outbreak, it remains to be seen if private sector investment will increase and stimulate growth (available evidence in any event suggests that private sector investment tends to follow, not lead, economic growth). 

With growth likely to remain slow, lower real interest rates and lower budget deficits are required to reduce the debt ratio and restore fiscal sustainability. These interest rates will more than likely increase if Moody’s decides to (finally) downgrade its rating of South African government debt.

With low economic growth and high real interest rates, stabilisation of the public debt ratio means that the budget deficit must be reduced. To reduce the budget deficit, government can: (i) increase taxes, (ii) decrease spending and (iii) increase taxes and reduce spending. Given that fiscal policy is unsustainable in South Africa, it is surprising that NT decided against increasing taxes (other than customary annual increases in the fuel levy and excise taxes) in this budget – many analysts were expecting some combination of higher personal income tax, VAT, and company taxes. As reasons for not raising taxes, it cites low expected economic growth, and that most of the efforts to reduce the budget deficit in the past five years have been centred on using tax increases. Even more puzzling, the budget granted real tax relief to taxpayers, as income tax scales were adjusted by more than expected inflation. 

All efforts to rein in the budget deficit therefore rely on government spending reductions. To this end, NT is proposing to reduce government spending by about R260 billion over the next three years. This reduction in spending is comprised of a R160 billion reduction in the wage bill, and a further R100 billion reduction in programme baseline reductions. At the same time, as a proposal for wage cuts, government is allocating even more money to prop up the balance sheets of many SoCs, with R60 billion allocated to Eskom and SAA (while the Minister referred to the Sword of Damocles when referring to SAA in his speech, a more apt analogy for government’s response to the financial crises facing many of its SoCs might rather be the paradox of Buridan’s ass). While government has announced plans for the restructuring of Eskom and has placed SAA in business rescue, so far there is no feasible consensus plan to address Eskom’s mounting debts and dire financial situation, which poses a systemic risk to the South African economy. 

Regarding the proposed reductions to the wage bill, NT believes that its target can be achieved through downward adjustments to cost-of-living adjustments, pay progression and other benefits. Furthermore, the Budget Review also states that pay scales at public entities and state-owned companies (SOCs) will be aligned with those in the public service to curtail wage bill growth and ‘excessive’ salaries at these entities. We are also told that government will discuss the options for achieving its desired wage bill reduction with unions. Given the precariousness of the public finances, and the understandable objections of workers and unions, one must ask why these discussions were not already in full swing by the time that the budget was tabled? 

Regarding the proposed cuts to government programmes, NT notes that it tried to limit these to underperforming or underspending programmes, and that the largest cuts will be in the human settlement and transport sectors. But, as NT acknowledges, any cuts to government programmes will negatively affect the economy and social services; the budget speech also states that the number of government employees has declined since 2011/12, which also affects the provision of public and social services adversely (the Minister explicitly mentioned increased classroom sizes, full hospitals, and too few police officers during his speech). 

Apart from the proposed spending cuts, the proposed allocation of spending is unsurprising and reflects long-standing government priorities: spending on basic education, post-school education and training, health and social protection takes up 13,6%, 6,7%, 11,8% and 11,3%, respectively. Increases in social grants range between 4 and 4,7%, which means small real increases in most social grants (only if inflation remains subdued). Worryingly, debt service costs are expected to take up more than 11% of total government spending (and is projected to exceed health spending by 2022/23). These costs are projected to grow by more than 12% by 2022/23 (almost double the growth in the fastest growing non-interest expenditure category). These figures vividly illustrate how a high and increasing debt-to-GDP ratio limits the scope for increased spending on important public and social services. 

Unless fiscal sustainability and the  balance sheets of SoCs are restored, the scope for the government to increase spending to combat poverty, rising inequality, and unemployment will be severely limited – as would the scope for countercyclical fiscal policy, should the local economy again slide into recession. The stakes are high, and the cost of indecisiveness is increasing.

Fight against Ebola virus requires more research

Dr Abdon Atangana, a postdoctoral researcher in the Institute for Groundwater Studies at the University of the Free State (UFS), wrote an article related to the Ebola virus: Modelling the Ebola haemorrhagic fever with the beta-derivative: Deathly infection disease in West African countries.

“The filoviruses belong to a virus family named filoviridae. This virus can cause unembellished haemorrhagic fever in humans and nonhuman monkeys. In literature, only two members of this virus family have been mentioned, namely the Marburg virus and the Ebola virus. However, so far only five species of the Ebola virus have been identified, including:  Ivory Coast, Sudan, Zaire, Reston and Bundibugyo.

“Among these families, the Ebola virus is the only member of the Zaire Ebola virus species and also the most dangerous, being responsible for the largest number of outbreaks.

“Ebola is an unusual, but fatal virus that causes bleeding inside and outside the body. As the virus spreads through the body, it damages the immune system and organs. Ultimately, it causes the blood-clotting levels in cells to drop. This leads to severe, uncontrollable bleeding.

Since all physical problems can be modelled via mathematical equation, Dr Atangana aimed in his research (the paper was published in BioMed Research International with impact factor 2.701) to analyse the spread of this deadly disease using mathematical equations. We shall propose a model underpinning the spread of this disease in a given Sub-Saharan African country,” he said.

The mathematical equations are used to predict the future behaviour of the disease, especially the spread of the disease among the targeted population. These mathematical equations are called differential equation and are only using the concept of rate of change over time.

However, there is several definitions for derivative, and the choice of the derivative used for such a model is very important, because the more accurate the model, the better results will be obtained.  The classical derivative describes the change of rate, but it is an approximation of the real velocity of the object under study. The beta derivative is the modification of the classical derivative that takes into account the time scale and also has a new parameter that can be considered as the fractional order.  

“I have used the beta derivative to model the spread of the fatal disease called Ebola, which has killed many people in the West African countries, including Nigeria, Sierra Leone, Guinea and Liberia, since December 2013,” he said.

The constructed mathematical equations were called Atangana’s Beta Ebola System of Equations (ABESE). “We did the investigation of the stable endemic points and presented the Eigen-Values using the Jacobian method. The homotopy decomposition method was used to solve the resulted system of equations. The convergence of the method was presented and some numerical simulations were done for different values of beta.

“The simulations showed that our model is more realistic for all betas less than 0.5.  The model revealed that, if there were no recovery precaution for a given population in a West African country, the entire population of that country would all die in a very short period of time, even if the total number of the infected population is very small.  In simple terms, the prediction revealed a fast spread of the virus among the targeted population. These results can be used to educate and inform people about the rapid spread of the deadly disease,” he said.

The spread of Ebola among people only occurs through direct contact with the blood or body fluids of a person after symptoms have developed. Body fluid that may contain the Ebola virus includes saliva, mucus, vomit, faeces, sweat, tears, breast milk, urine and semen. Entry points include the nose, mouth, eyes, open wounds, cuts and abrasions. Note should be taken that contact with objects contaminated by the virus, particularly needles and syringes, may also transmit the infection.

“Based on the predictions in this paper, we are calling on more research regarding this disease; in particular, we are calling on researchers to pay attention to finding an efficient cure or more effective prevention, to reduce the risk of contamination,” Dr Atangana said.
