We investigate intertemporal dominance conditions for comparisons of finite unidimensional streams of outcomes in discrete time. We follow Ekern's [1981, Time dominance efficiency analysis. Journal of Finance, 36, pp.1023-1034] approach based on unanimous net present value comparisons for...

Recently there has been a growing interest in the empirical association between income inequality and social mobility. Little is known on the normative nexus between both notions, however. In this paper, we axiomatically characterize a family of multiperiod social evaluation functions that...

We introduce an axiomatic framework to analyze the perception of inequality across distributions with different total income. The main result is the characterization of a new two parameters generalized version of the inequality equivalence criterion (IEC), the Flexible IEC (FIE). This criterion...

The analysis of many social phenomena requires to compare distributions of outcomes achieved by individuals belonging to different social groups, defined for instance by their gender, ethnicity, birthplace, education, age or parental background. When the groups are similarly distributed across...

We consider populations partitioned into groups, whose members are distributed across a finite number of classes such as, for instance, types of occupation, residential locations, social status of fathers, levels of education, health or income. Our aim is to assess the dissimilarity between the...

Ethnic heterogeneity can potentially be related to the occurrence of conflicts with longlasting economic effects. Two main measures of ethnic heterogeneity are employed in the econometric literature on ethnic diversity and conflict: the Gini heterogeneity or fractionalization index and the...

The evaluation of social risk equity for alternative probability distributions over the potential sets of fatalities is analyzed axiomatically. Fishburn and Straffin [Equity considerations in public risks valuation, Operatons Research 37 (1999), 229-239] have identified a necessary and...

We propose a generalization of the decomposition by population subgroups of the α-Gini index, the so-called multi-level subgroup decomposition. We demonstrate that all components obtained from the decomposition, can integrate in their functional form a parameter of inequality sensitivity being...
