The Magnus-Derek game

We introduce a new combinatorial game between two players: Magnus and Derek. Initially, a token is placed at position 0 on a round table with n positions. In each round of the game Magnus chooses the number of positions for the token to move, and Derek decides in which direction, + (clockwise) or − (counterclockwise), the token will be moved. Magnus aims to maximize the total number of position...

Variational Bewley preferences

This paper characterizes preference relations % not necessarily complete and transitive over Anscombe-Aumann acts f from a state space S to a convex set of consequences X. The main feature of this model are an a¢ ne utility function u on consequences, an ambiguity index on the set of priors over the state space, and a variational Bewley representation asserting that for all acts f and g f % g ,...
