A superadditive solution for cephoidal bargaining problems

We present a bargaining solution defined on a class of polytopes in \documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$\mathbb{R}^n$$\end{document} called “cephoids”. The solution generalizes the superadditive solution exhibited by Maschler and Perles for two dimensions. It is superadditive on a subclass of cephoids.
