– 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'
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...

– 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...
Journal Article
This paper investigates the process of adjustment in employment. A dynamic model is applied to a panel of six Tunisian manufacturing industries observed over a period of 25 years, from 1971 to 1996. Industries are assumed to adjust their labor inputs toward a desired level. A labor requirement...

– A bridge between micro and macro estimates?
The Nordic model relies on high tax rates to finance an extensive welfare state. If labour supply elasticities are large, the burden of financing the model can be large even if, arguably, the practice of providing subsidised goods that support labour supply is likely to mitigate these effects. We...

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...

– A counter-argument to the recommendation in the Mirrlees Review
The Mirrlees Review recommends that commodity taxation should in general be uniform, but with some goods consumed in conjunction with labour supply (such as child care) left untaxed. This article examines the validity of this claim in an optimal income tax framework. Contrary to the recommendation...
This paper examines the effects of health-oriented food tax reforms on the distribution of tax payments, food demand and health outcomes. We offer an illustration of how one can take into account the uncertainty related to both demand estimation and health estimates and to produce confidence...
– Economywide Analysis for Ethiopia and Uganda
Rapid urbanization is an important characteristic of African development and yet the structural transformation debate focuses on agriculture’s relative merits without also considering the benefits from urban agglomeration. As a result, African governments are often provided conflicting...
– Evidence from a Group-Based Aid Project in Mozambique
This paper evaluates the impact of an intervention to improve farming techniques and food security in the Gaza area of rural Mozambique. We examine the impact of a group-based approach to technology adoption in subsistence agriculture, using panel data collected by our research team on over 200...
