The inflation crisis of 2008 drew greater attention to the varying experiences of inflation in South Africa and, in particular, to the fact that different groups within society may have significantly differing inflation experiences. The groups may be defined according to income level, but may...

This paper explains how to build Lorenz Curves for income distributions and discusses their use for inequality measurement. A short conceptual background, a step-by-step procedure and a simple numerical example illustrate how to calculate and draw Lorenz Curves. A discussion on the use of Lorenz...

This paper illustrates how Crossing Generalised Lorenz (GL) curves can be used to identify the best income distribution on social welfare grounds within a set of alternative income distributions generated by different policy options. It starts by illustrating two alternative income distributions...

This paper illustrates how Lorenz Curves can be used to identify the best income distribution on social welfare grounds, within a set of alternative income distributions generated by different policy options. After highlighting some drawbacks of using specific functional forms of the Social...
