This paper estimates a variety of inequality indices to study the evolution of income and consumption inequality in Poland between 1998 and 2008. We use robust methods to adjust for the impact of extremely large observations. We also conduct statistical tests on inequality changes using methods,...

We decompose the generalized Lorenz order into a size and a distribution component. The former is represented by stochastic dominance, the latter by the standard Lorenz order. We show that it is always possible, given generalized Lorenz dominance between two distributions F and G, to find...

We assess whether global social welfare has improved in the last decades despite (or because of) the substantial increase in global population. We use for this purpose a relatively unknown but simple and attractive social evaluation approach called critical-level generalized utilitarianism...

This paper provides a normative appraisal of the Canadian equalization transfers system. For that sake, the two-dimensional dominance criteria introduced by Atkinson and Bourguignon(RES, 1982) are used to compare the distributions of private and public good before and after equalization...

In applied welfare economics, equivalence scales for household composition and size corrections, and appropriate price deflators are minimum requirements to perform interhousehold comparisons of welfare, measured via household income or consumption information. In practice, the information...

This paper compares ad valorem and specific taxes in asymmetric homogenous Cournot oligopolies with constant marginal costs. We show that for any given level of industry output, ad valorem taxes are superior to specific taxes in terms of revenue raised. If the tax rates are sufficiently high,...
