Measurement Issues for Adequacy Comparisons Among Pension Systems

In this paper, indexes are proposed in order to capture the degree to which a pension scheme 1) prevents poverty among the elderly, 2) enables smoothing of living standards after retirement and 3) induces both intra- and inter-generational solidarity.

Certainty equivalent citation: generalized classes of citation indexes

Drawing from the existing literature on risk and inequality measurement, we implement the notion of “certainty equivalent citation” in order (i) to generalize most of the h-type citation indexes (h-, g-,

t-, f-, w-index), and (ii) to highlight the centrality of the decision-maker’s preferences on distributive aspects (concentration aversion) for the ranking of citation profiles. In order to highlight the sensitivity of citation orderings with respect to concentration aversion, an application to both simulated and real citation profiles is presented.

Measuring Inequality of Opportunity through Between-Group Inequality Components

While inter-generational income mobility is commonly understood to be socially desirable in that it promotes equality of life chances, social desirability of intragenerational income mobility is a much more controversial issue, which is known to be concerned with inequality and uncertainty effects, as well as aversion to income fluctuations. In this paper social welfare effects of intra-generational income mobility are investigated from the perspective of an opportunity egalitarian social planner. We show that, given the trade-off between inequality and uncertainty effects, social desirability of income mobility strongly depends on the characteristics of income switchings which are required to be rewarding the more deserving individuals and/or compensating the more unlucky ones. In this sense, we suggest that egalitarianism of opportunity, more than aversion to intertemporal fluctuations, is crucial for motivating the optimality of empirically observed low degrees of income mobility as compared to perfect mobility processes (complete reversal).

Income Mobility Comparisons and Equivalizing Transformations

In the existing literature a separating line is drawn between deprivationand complaint-based inequality indices. In this paper we show that deprivationbased inequality orderings (eg. Gini index) can be replicated through the generalization of complaint-based inequality indices.

Measuring Income Mobility over Equivalent Adults

It is known that existing measures of intra-generational (within cohorts) redistribution induced by pension schemes may prove highly misleading in the presence of inter-generational (between cohorts) redistribution. In this paper we show that the Kakwani progressivity index, extended to account for both positive and negative individual tax liabilities, is a non-distorted measure of intra-generational redistribution in pension systems. The relevance of the distortion induced by inter-generational transfers is empirically shown in the comparison between pre- and post-reform Italian pension schemes from 1992 to 2004.

A Resource-Sensitive Framework for Defining and Measuring Equality of Opportunity in Health

The role and effect of structural changes in the economy, economic models and data generating processes has been the subject of vivid discussions in economics for a long time. In particular, the new difficulties arising in a globalized market economy have been the main source for a return of interest in this subject. Leaving aside the impact and effects of structural changes, we mostly concentrate on the possibility for detection as well as the recognition of main sources. With the same objective in mind, most of the researchers have been focusing on the behaviour of crucial macroeconomic variables in presence of exogenous events (Stock and Watson 1996). Especially econometric models, like in the neo-keynesian approach (Muellbauer 1978), and, auto-regressive ones, like time-varying ARCH model (Evans 1991) have been developed highlighting structural instabilities which characterize economic phenomena. In this paper, we investigate the Italian stock market in order to highlight the occurrence of structural changes by the use of analytical tools mostly used in econophysics.
