Theoretical and empirical studies exploring the effects of income inequality upon growth reach a disappointing inconclusive result. This paper postulates that one reason for this ambiguity is that income inequality is actually a composite measure of at least two different sorts of inequality:...

The purpose of this paper is to introduce and adopt a generalised version of Roemer's (1998) Equality of Opportunity (EOp) framework, which we call extended EOp, for analysing second-best optimal income taxation. Unlike the pure EOp criterion of Roemer (1998) the extended EOp criterion allows...

This paper is concerned with the measurement of the extent of deprivation when the available information is given by a set of dichotomous variables, and the data are summarised by the count distribution, i.e. the distribution of the number of dimensions in which an individual suffers from...

This paper addresses the problem of the normative evaluation of income tax systems and income tax reforms. While most of the existing criteria, framed in the utilitarian tradition, are uniquely based on information about individual incomes, this paper, building upon the opportunity egalitarian...

Using family income from the Panel Study of Income Dynamics (PSID), we apply Quantile Regression to estimate the Intergenerational Income Elasticity (IGE) by percentiles in the U.S. from 1980 to 2010. For the whole period, the IGE shows a Ushape across the income distribution, with maximum...

In this paper we argue that a better understanding of the relationship between inequality and growth can be obtained by shifting the analysis from the space of final achievements to the space of opportunities. To this end, we introduce the Opportunity Growth Incidence Curve (OGIC) that can be...

Conventional wisdom predicts that changes in macroeconomic conditions significantly affect income inequality. In this paper we hypothesize that the way in which macroeconomic conditions affect inequality depends on how these conditions influence the constituents of total inequality: inequality...

Individual income is determined by free-will actions related to the level of effort exerted and by opportunities determined by aspects beyond the individual's control, such as family background, race, place of birth or health endowments. Taking human capital as the main engine of development, we...

We propose a characterisation of an aggregate measure of growth that takes into account the initial economic conditions of individuals. Our measure is a weighted average of individual income growth with weights that are decreasing with the rank of the individual in the initial income...

This paper is concerned with the problem of ranking Lorenz curves in situations where the Lorenz curves intersect and no unambiguous ranking can be attained without introducing weaker ranking criteria than first-degree Lorenz dominance. To deal with such situations Aaberge (2009) introduced two...
