The Pietra term structures of financial assets

Eliazar, Iddo - In: Physica A: Statistical Mechanics and its Applications 390 (2011) 4, pp. 699-706

This paper explores an elemental connection between call options–the most commonly tradable financial derivatives, implied volatility term structures–critical “market information” emanating from call-option prices, and the Pietra index–a quantitative economic measure of societal...

Maximization of statistical heterogeneity: From Shannon’s entropy to Gini’s index

Eliazar, Iddo; Sokolov, Igor M. - In: Physica A: Statistical Mechanics and its Applications 389 (2010) 16, pp. 3023-3038

Physics and Information Theory commonly use Shannon’s entropy which measures the randomness of probability laws, whereas … principle of maximal entropy, we explore the maximization of statistical heterogeneity–for probability laws with a given mean …–in the four following scenarios: (i) Shannon entropy maximization subject to a given dispersion level; (ii) Gini index …

A hierarchy of lorenz curves based on the generalized tukey's lambda distribution

Sarabia, Jose-Mari - In: Econometric Reviews 16 (1997) 3, pp. 305-320

A hierarchy of Lorenz curves based on the generalized Tukey's Lambda distribution is proposed. Representations of the corresponding distribution and density function are also provided, together with popular inequality measures. Estimation methods are suggested. Finally, a comparison with other...

The sociogeometry of inequality: Part II

Eliazar, Iddo - In: Physica A: Statistical Mechanics and its Applications 426 (2015) C, pp. 116-137

The study of socioeconomic inequality is of prime economic and social importance, and the key quantitative gauges of socioeconomic inequality are Lorenz curves and inequality indices — the most notable of the latter being the popular Gini index. In this series of papers we present a...

On social inequality: Analyzing the rich–poor disparity

Eliazar, Iddo; Cohen, Morrel H. - In: Physica A: Statistical Mechanics and its Applications 401 (2014) C, pp. 148-158

From the Old Testament to the Communist Manifesto, and from the French Revolution to the Occupy Wall Street protests, social inequality has always been at the focal point of public debate, as well as a major driver of political change. Although being of prime interest since Biblical times, the...
