This paper studies the redistributive and revenue effects of bracket creep in Germany under various inflation scenarios and evaluates the feasibility to charge a rich tax to fight bracket creep for the income distribution in 2009. Using a tax micro-simulation model developed for the newly...

We study a fundamental conflict in economic decision-making, the trade-off between equality, equity and incentives, in a new experimental game that nests a voluntary contributions mechanism in a broader spectrum of incentive schemes. In a 2×2 design, we let subjects either vote on or...

Global and local Poverty has been subject of study since early times, now a day, it seems like poverty alleviation is one of the most important and complex issues countries and regions are facing, and dealing with. None the less, poverty measurements lack of standardization and...

Whereas the supply of redistribution is relatively easy to measure, the determinants of the demand for redistribution are controversially discussed in international literature. Economic theory typically models redistribution as the result of a voting mechanism; this is only inadequately...

The paper discusses the ∪-shaped relationship between the equivalence scale n^ε and the Gini index instead of considering the equivalence scale’s relationship to the generalised entropy measures, which was studied by Coulter, et al. (1992). An end-point condition is given for the ∪-shaped...

A comparison of the 2007-08 crisis with that of 1929 showed its extreme gravity, but it also may have implied that the old harmful mistakes would not be repeated. After four years, the crisis has not been solved and it even threatens to worsen. Neo-conservative Republicans claim that this is...

This paper empirically applies the statistical approaches to the phenomenon of polarization generated by Esteban, et al. (1999) and Gradín (2000) in order to quantify the evolution of the middle class in Mexico and the role of various household attributes in the formation of groups during...

This paper analyzes inequality in Iran's health system from a financing perspective. Through grouped data of household budget published by Iran Statistic Center (ISC) and Beta Lorenz curve introduced in Kakwani (1980), it has been tried to extract Beta Lorenz curve and Kakwani progressivity...

This paper proposes a new class of inequality indices based on the Gini’s coefficient. The properties of the indices are studied and in particular they are found to be regular, relative and satisfy the Pigou-Dalton transfer principle. A subgroup decomposition is performed and the method is...

The Gini coefficient or index is perhaps one of the most used indicators of social and economic conditions. In this paper we characterize the Gini index as the unique function that satisfies the properties of scale invariance, symmetry, proportionality and convexity in similar rankings....
