In this paper we apply two statistical models to the measurement of polarization to Israeli income data over the past decade in order to empirically detect income classes as sub-populations of incomes concentrated around an optimal number of poles. The statistical models compared are a...

Studies using the Gini Index as a measure of income inequality have consistently found a positive and significant effect of the Gini on both happiness and life satisfaction. Two new measures used here - the ratio of persons in the lowest income decile relative to the number in the highest, and...

In this paper we study income polarization by first comparing the efficiency of two statistical models to identify the number of poles in the income distribution empirically. The statistical models used are a multi-resolution analysis (MRA) and a log-normal approach (LNA). We then apply the...

Pillar 2 of the Australian retirement system was introduced in 1993 with contributions made by employers as a percentage of wages to be accumulated for employees until retirement. As originally introduced, the effect of this Pillar 2 system would have been to perpetuate wealth and income...

The affordability of housing has become a major topic of discussion in Germany among both social scientists and the public at large. Using data from the German Socio-Economic Panel (SOEP), we provide rent-income ratios over more than two decades and show how they change with households'...

This paper presents a methodology for comparing income rank volatility profiles over time and across distributions. While most of the existing measures are affected by changes in marginal distributions, this paper proposes a framework that is based on individuals’ relative positions in the...
