An indicator of pro-poorness of a growth profile associated with a distribution of income is a measure of the extent to which growth is biased towards the poor. This paper proposes a general approach to pro-poorness, called the progressive sequential averaging principle (PSA), relaxing the requirement of rank preservation due to growth. An endogenous benchmark for evaluating the growth of poor comes out naturally from this principle. A dominance relation on the basis of the above approach for a class of growth profiles is introduced through a simple device, called the PSA curve and its properties are examined in relation to the standard dominances in terms of the generalized Lorenz curve and the inverse generalized Lorenz curve. The paper concludes with an application to evaluate growth profiles experienced by the United States between 2001-2007 and 2007-2013. [less ▲]

This paper identifies a family of absolute consistent inequality indices using a weakly decomposable postulate suggested by Ebert (2010). Since one member employs an Atkinson (1970) type aggregation we refer to it as the Atkinson index of consistent inequality. A second member of this family parallels the Kolm (1976) index of inequality. Two innovative features of these indices are that no specific structure is imposed on the form of the index at the outset and no transformation of any existing index is considered to ensure consistency. Each of them regards an achievement distribution as equally unequal as the corresponding shortfall distribution. We apply these indices to study inequality in grip strength among 50+ year-old Europeans. [less ▲]
