The paper presents ab abstract definition of linear inequality concepts leading to linearly invariant measures and characterizes the class of linear concepts completely. Two general methods of deriving ethical measures are proposed. They imply an Atkinson-Kolm-Sen index and a new dual index reflecting the inequality of living standard. Then all separable social welfare orderings which generate ...

We present a class of decomposable inequality indices for ordinal data (e.g. self-reported health survey). It is characterized by well-known inequality axioms (e.g. scale invariance) and a decomposability axiom which states that an index can be represented as a function of inequality values in subgroups and subgroup sizes. The only decomposable indices are strictly monotonic transformations of ...

OBJECTIVE To analyze whether the relationship between income inequality and human health is mediated through social capital, and whether political regime determines differences in income inequality and social capital among countries. METHODS Path analysis of cross sectional ecological data from 110 countries. Life expectancy at birth was the outcome variable, and income inequality (measured b...

BACKGROUND In advanced economies, economic factors have been found to be associated with many health outcomes, including health-related quality of life (HRQL), and people's health is affected more by income inequality than by absolute income. However, few studies have examined the association of income inequality and absolute income with HRQL in transitional economies using individual data. Thi...

OBJECTIVE To analyze economic inequality (absolute and relative) due to family income in relation to the occurrence of preterm births in Southern Brazil. METHODS Four birth cohort studies were conducted in the years 1982, 1993, 2004, and 2011. The main exposure was monthly family income and the primary outcome was preterm birth. The inequalities were calculated using the slope index of inequa...

This study investigates the relationship between globalization and income inequality by developing a new globalization index based on economic growth. In addition two other indices of globalization, non-parametric Kearney and parametric principal component analysis are used as benchmarks to compare the results. The proposed new index is decomposed into four sub components. The index is also est...

This paper concerns some notes about the inequality index based on the ratios between lower and upper arithmetic means recently proposed by Zenga [2006]. Beside some definitions and notation given in section 2, we show (section 3) that the inequality measure proposed fulfills the population replication principle. In the remainder of the paper our purpose is to consider a population partitioned ...
