We examine the relationship between changes in a country’s public sector fiscal position and inequality at the top and bottom of the income distribution during the age of austerity (2006–13). We use a parametric Lorenz curve model and Gini-like indices of inequality as our measures to assess...

Three alternative inequality curves are considered as competitors of the classical Lorenz curve as descriptors of income inequality. The Bonferroni curve and the Zenga-07 curve appear to be essentially equivalent to the Lorenz curve. They each determine the parent distribution up to scale...

An ideal state of development, when viewed with fantasy, is nothing but a state or condition where light touches everybody without refraction. The diagonal line of the Lorenz Curve Framework represents such an ideal condition. In the presence of inequality, however, it deviates or refracts from...

Recently, a lot of attention is given to income variations occurring at the top of the income distribution. “What happens to the top 1%?” is a question of crucial importance on the political level (Occupy Wall Street Movement) as well as on income inequality measurement level. Despite this...

Similar looking Lorenz Curves can imply very different income density functions and potentially lead to wrong policy implications regarding inequality. This paper derives a relation between a Lorenz Curve and the modality of its underlying income density: Given a parametric Lorenz Curve, it is...

Index of refraction is found to be a good measure of economic inequality within the Lorenz curve framework. It has origin in geometrical optics, where it measures bending of a ray of light passing from one transparent medium into another. As light refracts according to characteristics of...
