This paper provides a single welfare measure to show the effects of consumer price changes upon households in Ireland between 1999 and 2010. This measure combines an efficiency component using a Linear Expenditure System (LES) and an equity component using the Atkinson Social Welfare Function....

The Gini coefficient features prominently in Amartya Sen's 1973 and 1997 seminal work on income inequality and social welfare. We construct the Gini coefficient from socialpsychological building blocks, reformulating it as a ratio between a measure of social stress and aggregate income. We...

This study provides new evidence on top income shares in Germany from the period of industrialization to the present. Income concentration was high in the nineteenth century, dropped sharply after World War I and during the hyperinflation years of the 1920s, and increased rapidly throughout the...

This paper is a review of the recent advances in the measurement of inequality. Inequality can have several dimensions. Economists are mostly concerned with the income and consumption dimensions of inequality. Several inequality indices including the most widely used index of inequality namely...

This paper is a review of recent developments of parametric and non-parametric approaches to decompose inequality by subgroups, income sources, causal factors and other unit characteristics. Different methods of decomposing changes in poverty into growth, redistribution, poverty standard and...

This paper focuses on the importance data issues to the analysis of growth, poverty and economic inequality. We introduce a number of major databases frequently used in applied research on growth, poverty and global and international inequality. A discussion of data quality, data consistency,...

This review covers a range of measures and methods frequently employed in empirical analysis of global income inequality and global income distribution. Different determinant factors along with quantification of their impacts and empirical results from different case studies are presented. These...

Income inequality can be measured at different levels of aggregation such as global, continental, international and national levels. Here we consider income inequality at regions defined as equivalent of continental and sub-continental levels. We investigate the economic disparity between...

Income inequality can be measured at different levels of aggregation such as global, continental, international and national levels. Here we consider income inequality at the national level but the focus is on the within country regional inequality. Regional inequality in income distribution in...
