p class="MsoNormal" style="margin-bottom: .0001pt; line-height: 150%;">The economic and environmental effects of a carbon tax in South Africa: A dynamic cge modelling approach South Africa’s National Treasury released its Carbon Tax Policy Paper in May 2013. The paper proposed a R120/tCO2-equiv. levy on coal, gas and petroleum fuels. Here, we model...
Article
The South African Government announced, in the 2008 Budget Review, the intention to tax the generation of electricity from non-renewable sources with 2c/kWh. The intention of the tax is to serve a dual purpose of managing the potential electricity shortages in South Africa and to protect the environment. The primary objective of this paper is to ev...
Article

A Computable General Equilibrium model is used to find the effects of a food voucher scheme on the economy in South Africa. If firms consider the issuing of vouchers as increased remuneration, they will hire fewer labourers. The higher labour cost increases the total cost of production and lowers supply. Real Gross Domestic Product decreases and th...
Article
Full-text available
South Africa's unallocated water resources have dwindled to precariously low levels. Furthermore, it is generally recognised by the authorities and specialists alike that it is likely that water demand will outstrip water supply within the next decade. Macro-economically and strategically speaking, the question therefore is how to make best use of...

The South African Government announced, in the 2008 Budget Review, the intention to tax the generation of electricity from non-renewable sources with 2c/kWh. This tax is to be collected by the producers/generators of electricity at the source. The intention of the tax is to serve a dual purpose of managing the potential electricity shortages in Sou...

The paper uses a static Computable General Equilibrium (CGE) model of South Africa and simulates various shocks to the price of electricity. We attempt di¤erent closures to the model and compare their respective e¤ects on the Consumer Price Index. In a CGE model, this is measuring the real appreciation of the exchange rate, or international trade c...
Article
A static computable general equilibrium model of South Africa is adapted to compare new taxes on water demand by two industries, namely forestry, and irrigated field crops. Comparisons are made with respect to both the short and the long run, in terms of three target variables, namely (i) the environment; (ii) the economy; and (iii) equity. Since t...

The paper uses a static computable general equilibrium (CGE) model of South Africa and simulates various shocks to the price of electricity. We try different closures to the model and compare their respective effects on the consumer price index, which in a CGE model is measuring real appreciation of the exchange rate, or international trade competi...
Article
Full-text available
South Africa, as an upper middle-income, resource-intensive developing country with an open economy, has to find innovative ways to combat poverty, promote economic growth and reduce the intensity of resource use, simultaneously. One option is to explore the plausibility of achieving a double dividend by levying a tax on water and energy and recycl...
Article
Full-text available
A CGE model of South Africa is used to find the potential for a double or triple dividend if the revenues raised from an energy-related environmental tax are recycled to households and industry through lowering existing taxes. Four environmental taxes and three revenue-recycling schemes are compared. The environmental taxes are (i) a tax on greenho...
Article
Full-text available
The South African government is exploring ways to address water scarcity problems by introducing a water resource management charge on the quantity of water used in sectors such as irrigated agriculture, mining and forestry. It is expected that a more efficient water allocation, lower use and a positive impact on poverty can be achieved. This paper...

In the 2008 Budget Review, the South African government announced its intention to levy a 2c/kWh tax on the sale of electricity generated from non-renewable sources. This measure is intended to serve a dual purpose of helping to manage the current electricity supply shortages and to protect the environment (National Treasury 2008). An electricity g...
Article
Full-text available
South Africa is in the grip of an electricity crisis marked by a euphemism known as “load shedding”. The demand for electricity has grown to the point that the supply reserve margin is often under threat, necessitating the electricity supplier to cut supply to some areas for various periods of time, or to shed load. This is a condition previously u...
Article
Full-text available
In the 2008 budget of the Minister of Finance, the South African Government proposed to impose a 2 cents/kilowatt-hour (c/kWh) tax on the sale of electricity generated from non-renewable sources; this tax is to be collected at source by the producers/generators of electricity. The intention of this measure is to serve a dual purpose of protecting t...
