Building back fairer from the COVID-19 pandemic in South Africa

Building back fairer from the COVID-19 pandemic in South Africa

On 27 August 2019, National Treasury released a document titled ‘Economic transformation, inclusive growth, and competitiveness: A contribution towards a growth agenda for the South African economy’. Perhaps as a response to the long title, the document became popularly known as “the 77-pager”. No document that proposes a substantial reform economic programme is universally embraced; however, the 77-pager did receive some important plaudits. For example, The Economist magazine described it as “replete with sensible ideas that could form the basis of a new ‘growth strategy’” (The Economist 2019). National Treasury (2019) estimated that the proposed reforms would, following implementation, raise potential growth by 2.3 percentage points (above the baseline) and create over 1 million additional jobs.

Working Paper

A climate change modelling framework for financial stress testing in Southern Africa

A climate change modelling framework for financial stress testing in Southern Africa

Central banks play a critical role in the economy, with policy levers that influence and are influenced by climate change. An important part of central bank interventions is conducting climate-related stress tests and scenario analysis to increase awareness in the financial sector of the effects of climate change, improve the integration of climate-related risks into financial companies’ decisions, identify important data gaps, and start building capacity to develop more advanced and accurate climate scenarios. These exercises, however, are a challenge to central banks and financial companies because of their complexity and the new data and tools required for scenario development and analysis. The development of scenarios for climate-related stress testing requires the integration of different model frameworks to assess the impacts of climate change, translate these impacts into macroeconomic scenarios, and evaluate the subsequent financial sector outcomes. This integration requires multidisciplinary skills such as the joint work of energy system modellers, climate scientists and macroprudential experts. This paper provides an overview of the modelling frameworks available for assessing climate change impacts in South Africa, covering both local and global models. This should assist financial institutions and regulators with developing partnerships to build scenarios and assess the impact of climate-related risks. Gaps in current models and modelling for financial stress testing are also identified as considerations for future research.

Who has been hit hardest by South Africa’s lockdown? We found some answers (The Conversation)

The Conversation published an op-ed by EPTD Division Director Channing Arndt, Senior Research Fellow Emeritus Sherman Robinson, and Scientist Sherwin Gabriel that stated in the case of South Africa, the lockdown policies are relatively stringent, and the economic impacts large. Along with analysis and recommendations, the authors said, “With a catastrophic global pandemic coming on top of more than a […]
