For important classes of symmetrically distributed random variables X the smallest constants C[alpha] are computed on the right-hand side of Chebyshev's inequality P(X[greater-or-equal, slanted]t)[less-than-or-equals, slant]C[alpha]EX[alpha]/t[alpha]. For example if the distribution of X is a...

This paper explain, analyze and apply in an example the original paper developed by Kopprasch, Boyce, Koenigsberg, Tatevossian, and Yampol (1987) from The Salomon Brothers Inc. Bond Portfolio Analysis Group. Please, be aware. This paper is for educational issues only. There is a Spanish version...

This article analyzes constrained Pareto efficient nonlinear income tax schedules that are monotonic chains to the left. It is demonstrated that as long as all individuals have a positive consumption at the tax schedule that maximizes the utility of the worst-off individual, the constrained...

We consider a two-sided buyers & sellers' market with indiviseble goods. Agents may trade many units of any of the items available. Previous research, documenting the case ofunit-flow trades, showed that the existence of substitutability or complementarity colligations between goods. These...

An open question in the study of quasiconvex function is the characterization of the class of functions which are sum of quasiconvex functions. In this paper we restrict our attention to quasiconvex radiant functions, i.e. those whose level sets are radiant as well as convex and deal with the...
