Differentiability is a convenient property of von Neumann-Morgensten utility functions which is almost always imposed but has not been translated into behavioral terms. In applications, expected ...

When u is a von Neumann-Morgenstern utility function on X × Y, Y is "utility independent" of X if u can be written as u(x, y) = f(x)g(y) + a(x) with f positive. This paper introduces a fundamental ...
