L. Ceriani, Chiara Gigliarano (2015), An Inter-temporal Relative DeprivationIndex in “Social Indicators Research”, Vol. 124, n. 2, pp. 427-443
Lang.: engReferee: Esperti anonimiRilev.: InternazionaleCategory: Articolo in rivista
Keywords: Relative deprivation; Inter-temporal measurement; Income distribution
Abstract: The paper provides an axiomatic characterization of a new class of relative deprivation indices. Relative deprivation is the feeling that an individual experiences when she compares herself with someone who is better off. We believe that individuals not only take care of their relative position with respect to others but also of their relative position with respect to their own past. Therefore, we introduce a history-regarding reference group, while in the traditional relative deprivation framework the reference group is only other-regarding.The new index is sensitive to the proximity of transfers in the reference groups: an individual may feel more deprived if an increase in achievements occurs close or far to her current position. The new index is illustrated with an application to EU countries.


Chiara Gigliarano, Francesco Balducci, Mariateresa Ciommi, Francesco Maria Chelli (2014), Going regional: An index of sustainable economic welfare for Italy in “Computers, Environment and Urban Systems”, Vol. 45, pp. 63-77
Lang.: engReferee: Esperti anonimiRilev.: InternazionaleCategory: Articolo in rivista
Keywords: Economic wel-being; Sustainability; regional studies; Beyond GDP
Abstract: The Index of Sustainable Economic Welfare (ISEW) is a monetary measure of sustainability and economicwelfare aimed at overcoming some of the limitations of the Gross Domestic Product (GDP). In particular itaccounts for the value of externalities, for the distribution of income and for the natural resources depletion.Since its formulation in 1989 by Daly and Cobb, the ISEW has been calculated for a number ofnations. More recently, there has been an increasing interest in assessing sustainable welfare also atsub-national levels.Following this trend, the aim of this paper is to provide an empirical application of the ISEW for Italyand for all its regions and macro-areas over the years 1999–2009. In particular, we compare the rankingof the Italian macro-areas and regions based on ISEW with the corresponding rankings based on GDP.This is the first empirical analysis in the literature that provides estimates and comparisons of the ISEWfor all the Italian regions and macro-areas over a long period of time.Another important novelty of this paper concerns the introduction of a weighting scheme to adjust privateconsumptions based not only on inequality but also on poverty.Empirical results show substantial differences between the regional ranking based on ISEW and thetraditional classification based on GDP, revealing, moreover, that the Italian regions are characterizedby a high variability in terms of their sustainable and economic welfare.


Chiara Gigliarano, Francesco Maria Chelli (2014), Measuring inter-temporal intragenerational mobility: anapplication to the Italian labour market in “Quality and Quantity”
Lang.: engReferee: Esperti anonimiRilev.: InternazionaleCategory: Articolo in rivista
Keywords: Occupational mobility; Indices; Italian labour market
Abstract: Aim of the paper is to provide a new class of mobility indices that takes into account the inter-temporal status movements over more than two periods of time. The index is obtained in two steps. First, an individual inter-temporal individual mobility index isprovided, which allows also for analysis of upward and downward mobility. Since memoryplays an important role when an individual makes comparisons with his past, a discountfactor has been introduced. Secondly, individual mobility indicators are aggregated overall the population, in order to obtain an index that allows for comparisons among differentsocieties. The empirical application analyzes the mobility of the occupational status in the Italian labour market within an inter-temporal framework, using the Italian Compulsory Communications system data.


Chiara Gigliarano, Francesco Maria Chelli (2014), A NONPARAMETRIC GINI CONCENTRATION TEST FOR LABOUR MARKET ANALYSIS in “Rivista italiana di economia, demografia e statistica”, Vol. 68, n. 3/4, pp. 135-142
Lang.: engReferee: Esperti anonimiRilev.: InternazionaleCategory: Articolo in rivista
Abstract: Aim of the paper is to analyse the differences in survival times of job contracts amongsubgroups of workers, based on age, gender, educational level, region.We examine the differences both in the length of the first job contract and in the waitingtime between the end of the first contract and the beginning of a new one.We apply the well known Gini index to the measurement of concentration in survival timeswithin groups of workers, and as a way to compare the distribution of survival times acrosssuch groups. We consider a test for differences in the heterogeneity of survivaldistributions, which may suggest the presence of a differential covariates effect on the jobcontract survival.The analysis is based on the Italian Compulsory Communications system data for theperiod between January 2009 and June 2012.


Chiara Gigliarano, S. Figini, P. Muliere (2014), Making classifier performance comparisons when ROC curves intersect in “Computational Statistic & Data Analysis”, Vol. 77, pp. 300-312
Lang.: engReferee: Esperti anonimiRilev.: InternazionaleCategory: Articolo in rivista
Keywords: ROC Curve; stochastic dominance; Model selection
Abstract: The ROC curve is one of the most common statistical tools useful to assess classifier performance. The selection of the best classifier when ROC curves intersect is quite challenging. A novel approach for model comparisons when ROC curves show intersections is proposed. In particular, the relationship between ROC orderings and stochastic dominance is investigated in a theoretical framework and a general class of indicators is proposed which is coherent with dominance criteria also when ROC curves cross. Furthermore, a simulation study and a real application to credit risk data are proposed to illustrate the use of the new methodological approach.
