A copula is a useful tool for constructing bivariate and/or multivariate distributions. In this article, we consider a new modified class of FGM (Farlie–Gumbel–Morgenstern) bivariate copula for constructing several different bivariate Kumaraswamy type copulas and discuss their structural...

In his 1984 paper in Management Science, McEntire conjectured that all concave utility functions satisfy his independence-from-irrelevant-assets (IIA) property. This paper shows that this conjecture is false. The paper provides several families of utility functions, all of whose members violate...

The paper derives a closed form solution for the maximal surplus generated by the pivotal mechanism in the case of a binary public good. The formula may be used to compare the pivotal mechanism to other mechanisms. An illustration is provided to demonstrate how such a comparison may be made.
