– LEAP model application
This study develops a scenario-based model to assess the current and future trends in energy demand in Africa and associated greenhouse gas emissions. Future energy demand is forecast on the basis of socio-economic variables such as gross domestic product, income per capita, population, and...
Working Paper

This paper develops a scenario-based model to identify and provide an array of electricity demand in Africa, and to derive them from the African power system of development. A system-based approach is performed by applying the scenario methodology developed by Schwartz in the context of the energy...

High levels of inflexible bilateral trade in southern Africa have limited the participation in the competitive short-term markets, leading to inefficient use of energy infrastructure and blocking the Southern African Power Pool’s long-term goal of transitioning from a cooperative to competitive...

– Proposed model for regional power sector integration in Africa
Regional power pools present a significant and potentially defining opportunity for African power systems to develop domestic energy resources, improve system reliability, and contribute to overall economic development. Hydropower is expected to play a significant role in many regional power pools...
Working Paper

As the technology of climate-dependent energy sources is improving—both cheaper and more efficient—the energy sources are becoming more accessible for many of the nations in Africa. However, little is known about the underlying climate that would therefore be harvested by renewable technologies...

The South African Revenue Service and National Treasury Firm-Level Panel is an unbalanced panel data set created by merging several sources of administrative tax data received during 2015. The four data sources that constitute the panel are: company income tax from registered firms who submit tax...
Working Paper

The manufacturing sector is an important source of productivity growth and exports. Manufacturing firms are generally more productive than firms in the agricultural or services sectors and are an important source of job creation. Little is known about the productivity performance of the sector and...

– An analysis with administrative data
This paper uses newly available firm-level tax data to evaluate the market structure in South African manufacturing sectors in the period 2010–12. To describe the market structure we compute markups for South African manufacturing firms and concentration indexes for 4-digit manufacturing sectors. We...

– New evidence from South Africa
This paper uses firm-level data from company tax declarations to analyse the complementary relationship between direct access to imported intermediate inputs and manufacturing firm performance in South Africa. There are three main findings. The first is on firm heterogeneity, showing that importers...
Working Paper
pdf
Existing South African work on firm-level data has been limited by access to large datasets that track firms over time. This paper overcomes this by analysing a new dataset of the population of manufacturing firms that are matched to their export transactions. South African firm-level exporting is...

In this paper, worker and job flows are estimated using the IRP5 data from the South African Revenue Services. The data used in this paper is from the 2011–14 tax years and contains information on more than 12 million individuals and nearly 300,000 firms. The main finding of the paper is that worker...

– Evidence from South African tax registers
In this paper we study the effects of various tax schedule discontinuities on the behavior of small firms using high-quality and population-wide tax register data from South Africa. We use the bunching method to analyse how these discontinuities affect the firm-size distribution. We first examine...

– Preliminary study of the Inga 3 Dam
Large hydropower dams are at the centre of a debate weighing the value and costs of renewable energy against the risks of climate change. The debate is especially relevant on the African continent, which offers vast hydropower potential, but which is exposed to possible climatic changes. This paper...
This special section contains a series of five articles focused on energy and climate change in sub-Saharan Africa. It is well known that energy demand in sub-Saharan Africa is increasing rapidly and that many countries struggle to meet demand. Failure to meet energy demand reduces living standards...
