A large literature has accumulated which examines how the optimal solution of an agent maximising the expectations of a real-valued function depending on a rendom parameter p and the agents's behaviour x reacts to pertubations in the first and second moments of p. In this literature p is given...

This paper studies aspects of sequential choice (and elimination) through the ‘routewise’ application of choice. (A choice is a mapping of the subsets of a set X into their respective subsets.) This approach sheds some further light on the ‘path-independence’ of choice, as well as on the...
