Abstract

A computable general equilibrium model linked to a microsimulation model is applied to assess the potential short-term effects on the South African economy of the ongoing COVID-19 pandemic. With a particular focus on distributional outcomes, two simulations are run, a mild and a severe scenario. The findings show significant evidence of decline in economic growth and employment, with the decline harsher for the severe scenario. The microeconomic results show that the pandemic moves the income distribution curve such that more households fall under the poverty line while at the same time, inequality declines. The latter result is driven by the disproportionate decline in incomes of richer households while the poorest of the poor are cushioned by government social grants that are kept intact during the pandemic. The COVID-19 pandemic is still unfolding and its economic modelling as well as the data used to operationalise the model will need to be updated and improved upon as more information about the disease and the economy becomes available.

摘要

一个与微观模拟模型相联系的可计算一般均衡模型被用于评估当前新冠疫情对南非经济的潜在短期影响。特别关注分配结果,进行了两次模拟,一个是轻度情景,一个是重度情景。研究结果显示出经济增长和就业下降的显著证据,重度情景下的下降更为严重。微观经济结果表明,疫情使收入分配曲线发生变动,更多家庭落入贫困线以下,与此同时不平等程度下降。后一个结果是由较富裕家庭收入不成比例的下降推动的,而最贫困的穷人则受到疫情期间保持不变的政府社会补助金的缓冲。新冠疫情仍在发展,随着关于该疾病和经济的更多信息可用,其经济建模以及用于实施该模型的数据将需要更新和改进。
