– 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
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'

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...

– 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...
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...

Professor Stephen Jenkins (this issue) has conducted an extremely careful and insightful analysis of two datasets, WIID and SWIID. In this short response, we focus on his review of the WIID, maintained and published by UNU-WIDER in agreement with the World Bank. We wish to highlight at the outset...

Nigeria is governed by a federal system, hence its fiscal operations also adhere to the same principle, a fact which has serious implications on how the tax system is managed. The country’s tax system is lopsided, and dominated by oil revenue. It is also characterized by unnecessarily complex...

In the beginning of the 1980s, Cameroon witnessed a sustained rate of growth, associated essentially with the boom in the oil sector. Increased budgetary and extra-budgetary resources generated by this sector helped to raise the investment rate in the economy, and to maintain a reasonable level of...

In evaluating tax reform in the developing countries, one first needs to determine what is the unique role of the tax system in each particular country. One of the key reasons for undertaking tax reforms in Kenya was to address issues of inequality and to create a sustainable tax system that could...

Ghana’s tax reforms constitute the major policy instrument needed to accelerate growth and poverty reduction. Over the past two decades, the government has consistently spent more revenue than it is able to generate and the gap is often financed with foreign aid which has perpetuated the country’s...

In 1991 the Ethiopian Revolution Democratic Front (EPRDF) toppled the old ‘socialist’ regime that had ruled the country for seventeen years. In contrast to the previous policy regime of hard control, EPRDF initiated a wide range of reforms that covered not only the tax system but also the exchange...
