We examine some ordinal measures of inequality that are familiar from the literature. These measures have a quite simple structure in that their values are determined by combinations of specific summary statistics such as the extreme values and the arithmetic mean of a distribution. In spite of their common appearance, there seem to be no axiomatizations available so far, and this paper is intended to fill that gap. In particular, we consider the absolute and relative variants of the range; the max-mean and the mean-min orderings; and quantile-based measures. In addition, we provide some empirical observations that are intended to illustrate that, although these orderings are straightforward to define, some of them display a surprisingly high correlation with alternative (more complex) measures.

Resilience has become an important topic in many social sciences. Numerous individual choices and economic and demographic outcomes are likely to be influenced by people’s resilience. School performance, work absenteeism and burnout, longevity, the quality of sleep and health-risk behaviors such as substance abuse are some examples. Similarly, it is of high policy relevance to understand the determinants of both individual resilience (such as educational, marital and occupational status) and ecological resilience (such as climate change). Empirical work designed to uncover such relationships suffers from the absence of a resilience measure applicable in the context of large data sets. We fill this gap by proposing a specific measure that is characterized by a set of natural properties. After an introduction to the notion of resilience and its attributes, we argue why these conditions have intuitive appeal. Finally, we provide illustrating examples and derive our main characterization result. [less ▲]

The paper discusses a one-parameter generalization of individual relative deprivation measures to a two-period setting that differs from earlier approaches. The parameter is, by definition, independent of the income distributions under consideration—it is to be chosen by a social planner. Its value has an intuitive interpretation: it represents the additional weight assigned to the income shortfalls associated with agents who passed the individual in question when moving from yesterday’s income distribution to today’s. Therefore, the choice of this parameter represents an important value judgment on the part of a social planner regarding the relative impact of being left behind. As a special case, it is illustrated how the well-known Yitzhaki index can be extended to this environment. [less ▲]

This paper analyzes the effects of the inclusion of past experiences in measuring current material deprivation. The method followed generalizes the proposal of Bossert, Ceriani, Chakravarty and D'Ambrosio (2014) by adapting the class of indices on the measurement of poverty over time of Dutta, Roope and Zank (2013). An application to the analysis of material deprivation within EU countries is then provided. Following the path of material deprivation experienced by each individual over time yields a picture which differs from that in the annual results. Since the measurement of material deprivation is used by the EU member states and the European Commission to monitor national and EU progress in the fight against poverty and social exclusion, the results suggest that time cannot be neglected. Countries should not only be compared based on their year-by-year results, but additional information is gained by following individuals over time and producing an aggregate measure once dynamic considerations are taken into consideration.

We provide a characterization of a class of rank-mobility measures. These measures generalize the Kemeny measure that is well-known from the literature on measuring the distance between orderings. We use replication invariance to ensure that our measures are applicable in variable-population settings. The rank-based approach to mobility has a natural connection with the study of social status. Rank-based measures are widely applied in empirical research but their theoretical foundation is still in need of further investigation, and we consider our approach to be a contribution towards this objective.

Individual well-being is multidimensional and various aspects of the quality of life need to be jointly considered in its measurement. The literature on the subject has proposed many indices of multidimensional poverty and deprivation and explored the properties that are at the basis of these measures. The purpose of this chapter is to add intertemporal considerations to the analysis of material deprivation. We employ the EU-SILC panel data set, which includes information on different aspects of well-being over time. EU countries are compared based on measures that take this additional intertemporal information into consideration. If we follow the path of material deprivation experienced by each individual over time we obtain a picture which differs from the annual results. Since the measurement of material deprivation is used by the EU member states and the European Commission to monitor national and EU progress in the fight against poverty and social exclusion, our results suggest that time cannot be neglected. Countries should not only be compared based on their year by year results but additional information is gained by following individuals over time and producing an aggregate measure once time is taken into account.

We propose and characterize a generalization of the classical linear index of individual deprivation based on income shortfalls. Unlike the original measure, our class allows for increases in the income of a higher-income individual to have a stronger impact on a person’s deprivation the closer they occur to the income of the individual whose deprivation is being assessed. The subclass of our measures with this property is axiomatized in our second result. [less ▲]

We propose a characterization of a popular index of multidimensional poverty which, as a special case, generates a measure of material deprivation. This index is the weighted sum of the functioning failures. The important feature of the variables that may be relevant for poverty assessments is that they are discrete in nature. Thus, poverty measures based on continuous variables are not suitable in this setting and the assumption of a discrete domain is mandatory. We apply the measure to European Union member states where the concept of material deprivation was initiated and illustrate how its recommendations differ from those obtained from poverty measures based exclusively on income considerations.

We provide an axiomatic treatment of the measurement of economic insecurity, assuming that individual insecurity depends on the current wealth level and its variations experienced in the past. The first component plays the role of a buffer stock to rely on in case of an adverse future event. The second component determines the confidence an individual has on her ability to overcome a loss in the future. Two classes of linear measures are characterized with sets of plausible and intuitive axioms and, for each of these classes, an important subclass is identified. [less ▲]

We examine the measurement of individual poverty in an intertemporal context. Our aim is to capture the importance of persistence in a state of poverty and we characterize a corresponding individual intertemporal poverty measure. Our first axiom requires that intertemporal poverty is identical to static poverty in the degenerate single-period case. The remaining two properties express decomposability requirements within poverty spells and across spells in order to reflect the persistence issue. In addition, we axiomatize an aggregation procedure to obtain an intertemporal poverty measure for societies and we illustrate our new index with an application to EU countries. [less ▲]

This paper characterizes an index that is informationally richer than the commonly used ethno-linguistic fractionalization (ELF) index. Our measure of fractionalization takes as a primitive the individuals, as opposed to ethnic groups, and uses information on the similarities among them. Compared to existing indices, our measure does not require that individuals are pre-assigned to exogenously determined categories or groups. We provided an empirical illustration of how our index can be operationalized and what difference it makes as compared to the standard ELF index. This application pertains to the pattern of fractionalization in the USA. [less ▲]
