The most general and central principle of social and economic optimality and justice is shown to be equal freedom. The standard and central case is that of freedom valued for the choice it permits. Allocations abiding by this principle are characterized, with the main structures of constraints...

This study validates the microeconomic model defining the evolution of personal incomes in the U.S. Because of a large portion of population not reporting any income, any comprehensive modeling of the overall personal income distribution (PID) is complicated. Age-dependent PIDs allow overcoming...

This paper analyzes the evolution of pay inequality in Cuba from the early 1990s through 2004, during what was known as the “Special Period in Times of Peace” and after. We measure pay inequality across sectors and regions, using the between-groups component of Theil’s T statistic, and we...

Inequality measures are often presented in the form of a rank ordering to highlight their relative magnitudes. However, a rank ordering may produce misleading inference, because the inequality measures themselves are statistical estimators with different standard errors, and because a rank...

The paper provides an examination into the measures of multidimensional inequality proposed in the past few years, their properties and majorization criteria. It offers a generalisation of Bourguignon index proposed so that it includes Tsui measures (1999) while preserving the virtues of...

We analyse the distribution of household wealth in Spain using the first wave of the Spanish Survey of Household Finances, conducted by the Bank of Spain in 2002. We study the distribution of the different wealth components and, using inequality decomposition techniques, we assess the...

This work concentrates in the fundamental ideas that constitute the existing theoretical framework of the poverty measurement from the 1960’s to the state-of-the-art, with an extended comment on the more relevant issues, the presentation of more influencing approaches and the probable path of...

We introduce a one-parameter class of individual deprivation measures. Motivated by a suggestion of Runciman, we modify Yitzhaki’s index by multiplying it by a function that is interpreted as measuring the part of deprivation generated by an agent’s observation that others in his reference...

We analyze behaviour and motivations of a sample of about one thousand consumers purchasing “fair trade (FT) goods”, i. e. food and artisan goods which include socially responsible (SR) characteristics and a price premium for primary product producers with respect to equivalent non SR...

This paper analyzes the relationship between bipolarization and inequality, welfare and poverty measures. First, we clarify the similarities and differences between bipolarization and inequality measures. Second, it is shown that bipolarization is the difference between the welfare levels of the...
