With a 7% fiscal deficit on the Gross Domestic Product (GDP) projected by the National Treasury for the 2020/21 financial year, it would not take long to arrive at a dangerous level of debt at the rate that South Africa is borrowing. Although the South African Reserve Bank Governor, Lesetja Kganyago, does not consider a debt to GDP rate of 60% a disaster, he did express his concern regarding the country’s fiscal deficits being over 6% of the GDP.

Governor Kganyago presented a public lecture at the University of the Free State (UFS) on 4 March 2020, focusing on how we should use macro-economic policy and its role in our economic growth problem.

Unsustainable policies 
South Africa’s fiscal situation is not about tight monetary policy. According to the Governor: “Weak growth is endogenous in our fiscal problems. We cannot keep doing what we are doing and hope that growth will recover and save us. Growth is low, in large part, because of unsustainable policy.”

Avoiding an impending crisis
To address the problem, as a policymaker with more than 20 years’ experience, the Governor suggested that the recommendations made by Minister Tito Mboweni be taken into consideration. “The Minister of Finance, Tito Mboweni, is a man who says things that are true even when they are unpopular. His message is that we have to reduce spending and he is right to put this at the centre of our macro-economic debate,” said Governor Kganyago.

The state needs a radical economic turnaround strategy which is able to diminish the risk of losing market access and being forced to ask the International Monetary Fund for help. Governor Kganyago is positive that such a reformative tactic would go beyond monetary policy and ensure that the interest bill ceases to claim more of South Africa’s scarce resources.

On 14 May this year, Dr DW Bester received a DPhil in Statistics from the University of Oxford. The entire ceremony, which was held in the Sheldonian Theatre in Oxford, was conducted in Latin, as has been the case for the past 800 years.

Dr Bester completed his undergraduate studies and his honours degree at the University of the Free State (UFS). “At first, I was only planning to study for a master’s degree, but was privileged to get an opportunity to do a PhD as well. I didn’t think twice!” he says.

Studies at the University of Oxford


Universities in England do not require a master’s degree for PhD studies. With the help of Prof Max Finkelstein from the UFS Department of Mathematical Statistics and Actuarial Science, Dr Bester registered for the DPhil programme in Statistics directly after his honours studies.

“The title of my thesis was: Joint survival models: A Bayesian investigation of longitudinal volatility. It dealt with a problem in the medical field to determine the cause of stroke risk: is it the absolute level of blood pressure, or the volatility thereof? The analysis of this question led to interesting models which needed advanced application techniques. I had to study these techniques and write programmes for their application.

Although Dr Bester is working currently as the technical head of a company that calculates insurance for power stations, satellites, rockets, and cyber risks, he would like to continue working with his Oxford supervisor in future to make the techniques they have developed more accessible for researchers outside of the field of statistics.
 
“Studying at Oxford requires hard work, perseverance, and a lot of luck. Luck plays a big role, since there are no guarantees that hard work will ensure you a spot in one of the top universities.

Regarding his studies at Oxford, Dr Bester thinks back on his exposure to the GNU/Linux operating system, and free software. “I have seen how valuable this is for analyses in practice. I also had the privilege of meeting the father of free software, Richard Stallman,” Dr Bester says.

2011 Rhodes Scholar

He was elected as Rhodes Scholar in 2011. According to Dr Bester, who has been interested in Mathematics since high school, the Rhodes scholarship was something of a fluke. He applied for the Rhodes scholarship on the recommendation of Prof Robert Schall of the Department of Mathematical Statistics and Actuarial Science.

Role of the UFS in his successes


In addition to the continued support from the team of passionate professors and lecturers at the UFS, the actuarial degree at the UFS is fraught with statistics. Emphasis is also placed on Bayesian statistics. This was crucial to his studies at Oxford. According to Dr Bester, this topic is emphasised strongly in the international statistics community.

Dr Bester regards the work done by two of his lecturers, Michael von Maltitz and Sean van der Merwe, among his highlights at the UFS. Since our first year, they have created an atmosphere of camaraderie among the students. “I think this contributed to the success of everybody. They also make an effort to present topics outside of the syllabus regularly,” says Bester.
