The economic effects of the lockdown period in South Africa will be devastating. We simulated the industry level capacity constraints imposed by the lockdown regulations since 27 March 2020 on all industries in South Africa by reducing the amount of capital and labour available for production. We found a decrease in real GDP to 10% below the baseline level in 2020, and recovery of all industries and macroeconomic variables towards the baseline by 2027. Industries that are suffering and would continue to suffer are the hospitality and tourism industry and all industries related to it, such as transport services, as well as beverages and tobacco. Manufacturing in general is also hard hit because they were prohibited to let large groups of labourers enter their premises. The model shows that most manufacturing will suffer throughout the forecast period, which was modelled up to 2027.

Purpose The purpose of this paper is to investigate how a drought which initially affects agricultural productivity can ultimately affect an entire economy. The study aims to assess the magnitude of the impact as well as highlight key issues that can inform the implementation of drought mitigation programmes. Design/methodology/approach The paper presents the literature on the economic impact of drought and uses a computable general equilibrium model where productivity shocks are applied to the agricultural industries following which the resulting impacts on the rest of the sectors of the economy are obtained. Findings The findings show that the key macroeconomic variables, namely, real GDP, industry output, employment, the trade balance and household consumption are negatively affected by the drought shock. Practical implications The results point to the fact that in the absence of drought mitigation mechanisms, the occurrence of even a short drought as modelled in this paper can impose substantial socioeconomic losses. Originality/value First, a general equilibrium framework which uses climate and economic data when evaluating the social-economic impacts of drought is used. Most studies employ partial equilibrium analysis in analysing drought impacts on specific sectors or crops within a limited geographical area. Others use global or multi-regional models which impose averages on the observed impacts. The current study provides valuable insights on the potential damage which droughts can impose on a single economy. This gives a basis for decision making to support drought mitigation policies and programmes.

The South African National Treasury expected a revenue shortfall of R48.2 billion in 2017/18 and proposed tax policy measures to raise an additional R36 billion in 2018/19. A key component to raise the additional revenue was a 1% point increase in the VAT rate to 15% effective from 1 April 2018. The increase in the VAT rate was not welcomed as it would increase the cost of living, especially for the poor. We investigate the potential economy‐wide and regional impacts of raising VAT and increasing public spending on education and health. We do this by developing and applying a multi‐regional model of the South African economy that includes detailed tax and spending features. In this model, when we increase VAT, the impacts are driven by the direct shock to the model, accompanied by differences in regional economic activity. We find that effects on GDP vary between regions but are generally negative.
