This paper discusses the importance of intra-generational equity to sustainable development. It outlines a number of methodologies for measuring income inequality in the economy, and presents several possible ways of incorporating the impact of distributional effects into measures of welfare in the economy. The authors highlight in particular an index developed by Atkinson (Atkinson, A.B., 1970...

In this paper the concept of unbounded Fredholm operators on Hilbert C∗modules over an arbitrary C∗-algebra is discussed and the Atkinson theorem is generalized for bounded and unbounded Feredholm operators on Hilbert C∗-modules over C∗-algebras of compact operators. In the framework of Hilbert C∗-modules over C∗-algebras of compact operators, the index of an unbounded Fredholm operator and the...
