This paper is concerned with the problem of ranking Lorenz curves in situations where the Lorenz curves intersect and no unambiguous ranking can be attained without introducing weaker ranking criteria than first-degree Lorenz dominance. To deal with such situations Aaberge (2009) introduced two...

Consider an income distribution among households of the same size in which individuals, equally needy from the point of view of an ethical observer, are treated unfairly. Individuals are split into two types, the dominant and the dominated. We look for conditions under which welfare and...

This article provides a simple proof of the Lorenz dominance criterion for two non-decreasing income transformations. The criterion is extended the most general case, with only very mild restrictions on the form of initial income distribution or the properties of the income transformations.

This paper proposes a test for Lorenz dominance. Given independent samples of income or other welfare related variable, we propose a test of the null hypothesis that the Lorenz curve for one population is dominated by the Lorenz curve for a second population. The test statistic is based on the...

This paper examines the changes in social welfare in Singapore using Labour Force Survey data. To study the changes and dominance, both ordinal and cardinal measures are used. By Lorenz Dominance social welfare in Singapore during 1999 is less than in 1991 while unambiguous conclusion cannot be...

We use the heterogeneous agents model of Aiyagari and McGrattan (1998) to analyze the redistributive effects of a negative income tax policy, which combines a flat rate tax with a fully refundable credit ("demogrant"). This issue has been previously considered in the context of static partial...

In a distribution problem, and specifically in bankruptcy issues, the Proportional (P) and theEgalitarian (EA) divisions are two of the most popular ways to resolve the conflict. TheConstrained Equal Awards rule (CEA) is introduced in bankruptcy literature to ensure that noagent receives more...

This paper considers the problem of measuring segregation when groups form a hierarchy whereby some groups have greater economic status than others. While existing measures of segregation address the case where people are unequally distributed across groups with the same economic status, concern...

The generalised Lorenz criterion is widely used for making welfare comparisons within and across countries on the basis of their income distributions. Experimental studies have challenged this way of proceeding by showing that the principle of transfers, which underlies the generalised Lorenz...
