### Three 'I's of Poverty Curves, with an Analysis of UK Poverty

The forte of generalized Lorenz curves (Shorrocks, 1983) and poverty deficit curves (Atkinson, 1987) is that they permit the checking of poverty dominance criteria.3 But TIP curves also have this property, as we shall show. 3. Poverty dominance Given the poverty line z, denote a typical index in the class P by P(xlz), and a

### EXTENDED BI-POLARIZATION AND

However, as with Lorenz curves, it is possible to have intersecting polariza tion curves. As do Lorenz curves, polarization curves induce only a partial or dering over income distributions, while the shaded area under the polarization curve in Figure 1 (P. 0) induces a complete ordering (like the Gini coefficient).

### Introduction - Science Publishing Group

For intersecting Lorenz curves alternative inequality measures have to be defined. The most frequently used is the Gini coefficient, G (Gini, 1914). Using the Lorenz curves, this coefficient is the ratio between the area between the diagonal and the Lorenz curve and the whole area under the diagonal. The formula is ³ 1 0 G 1 2 L(p)dp

the Gini coe cient or index (see [16]) and the Pietra index (see [17]). The Gini index is the ratio of the area between the 45 line and the Lorenz curve to the total area under the 45 line. Equivalently, the Gini index is twice the area between the Lorenz curve and the line of perfect equality. The Pietra index is the maximum value of the gap

### INTERNATIONAL COMPARISONS OF EARNINGS

Both the Gini and Theil indices, however, have a common disadvantage. If they are derived from distributions with intersecting Lorenz curves, that is, curves showing the relationship between the cumulated percentage of earnings and the cumulated percentage of earners, meaningful comparisons of the indices become problematic (Braun, 1988).
