– Accounting for inequality changes in Spain during the recession
The author discusses a new approach which decomposes inequality into the contributions of population groups by income sources. The author estimates a matrix with rows and columns which indicate different population groups and income sources, respectively, with each element indicating the marginal...
After 20 years of contributions to income inequality research, the World Income Inequality Database (the WIID) is getting a new expansion that will greatly strengthen knowledge on inequalities. UNU-WIDER is now working to produce a user-friendly companion database to the classic WIID that will...

– 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...

– Explaining income distributions with ‘decompositions’
The understanding of inequality requires the analysis of changes in income distributions across countries and over time as well as the identification of its drivers. To achieve this we use different statistical tools to identify the distributional patterns and summarize the results using inequality...

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...
Income inequality is the result of complex processes with multiple interacting driving forces but understanding those drivers in emerging economies is particularly difficult because of data and analytical challenges. While most middle-income countries produce comprehensive household surveys these...

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...

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...

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...

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...
