– Comment on 'Redistribution, inequality, and growth: new evidence'
An influential paper by Berg et al., ‘Redistribution, inequality, and growth: new evidence’, uses the SWIID data to examine the impact of inequality and redistribution on growth in both developing and developed countries. It finds that while inequality is harmful for growth, redistribution does not...

In this paper, we use the World Income Inequality Database to assess the main trends in inequality within countries since around 1990. We cope with the heterogeneity in the original information (regarding the measure of resources, equivalence scale, etc.) by focusing on the trends rather than on the...

– An integrated approach
In large parts of the world, income inequality has been rising in recent decades. Other regions have experienced declining trends in income inequality. This raises the question of which mechanisms underlie contrasting observed trends in income inequality around the globe. To address this research...

– Accounting for inequality changes in Spain during the recession
I discuss a new approach which decomposes inequality into the contributions of population groups by income sources. I estimate a matrix with rows and columns which indicate different population groups and income sources respectively, with each element indicating the marginal change in the inequality...

– A policy synthesis
The Republic of South Africa faces the imperative of escaping economic stagnation. This paper seeks to synthesize results from a series of research efforts, including but not limited to the work conducted under the UNU-WIDER project on ‘Regional growth and development in Southern Africa’, and...

pdf
– A firm-level analysis
We investigate the relationship between the corporate income tax burden and firm size in South Africa using a panel dataset from companies’ tax returns. We find that medium-sized companies are experiencing the lowest effective tax rate, while the smallest companies are facing the highest effective...
Working Paper
pdf
Traditionally, much of the research on economic growth drivers has been focused on small and medium enterprises. In recent years the academic focus on small businesses has shifted to a particular group of firms that are interesting from an economic growth and policy development perspective, namely...

– Experience from Southern Africa
Southern African countries’ interest in biofuel is due of its rural development potential. Finding models to optimize this benefit is therefore paramount. High-energy-density crops with low perishability allow farmers to grow small quantities on existing lands. Highly perishable, low-density crops...

– Regional development versus national imperatives
This paper highlights the key strategies, both regional and domestic, that have led to the current structure of the poultry value chain in Southern Africa. While large firm strategies in poultry have been found to be regional in nature, and important regional developments in soybean production...

– A look forward
This paper assesses biofuels technology readiness and provides foresight to biofuels development in Southern Africa. Efficient conversion pathways, coupled with biomass from waste or high-yielding energy crops, reduces both the costs of biofuels production and the environmental impacts. Currently...
Working Paper
pdf
The Southern African region, from a purely biophysical perspective, has huge potential for biofuel production, especially in Mozambique and Zambia. Although many of the soils are sandy and acidic, with careful management and correct fertilization, they should be highly productive. We suggest that...
Working Paper

World biofuel production has been increasing to improve energy security and mitigate global warming. Southern Africa’s bioenergy demand could increase with South Africa’s planned fuel blending mandates, triggering increased demand for feedstocks and agricultural land. Ensuring sustained production...
Working Paper
pdf
Rapid population growth, urbanization, and income growth are triggering increased demand for high-value agricultural products across Southern Africa with scope for gains from trade and regional integration. We analyse the animal feed to poultry value chain in Zambia focusing on the industry...

– Implications for local suppliers in Zambia
The last two decades have seen rapid economic growth in Zambia and the proliferation of foreign supermarket chain stores. However, this growth has translated into neither significant job creation nor significant poverty reduction. Furthermore, while the expansion of supermarket chains in Zambia has...
Working Paper
pdf
Given likely increases in biofuel demand across Southern Africa, we identify suitable production models in Zambia for the Southern African market. This is crucial given, on the one hand, the problems of contract failure and transaction costs that plague outgrower models in Southern Africa and, on...

– Competition in road transportation of perishable goods between Malawi, South Africa, Zambia, and Zimbabwe
Rapid urbanization and rising income levels in Southern Africa have increased the consumption of perishable and processed food products. This paper relies primarily on firm-level interview data to assess competition and bottlenecks in transporting time-sensitive perishable products across borders...
