Resumen:
A cake has to be divided fairly between two people. A well-known algorithm for cake-cutting recommends that one of them cuts the cake into two pieces, while the other picks the piece she likes the most. But now consider Anna and Berta. Say Anna, the youngest kid, cuts the cake. She looks happy; she is actually satisfied with her performance until Berta, the oldest sister, announces: ?Oh, of course I pick the left one!?, and goes away with her piece. Anna ends up crying: ?Please, let me cut again. I made a mistake!?What is going on? The preferences of one of the players change once she learns about (what she takes to be) the preferences of the other player. Normally, allocation problems motivate the search for appropriate algorithms. But most well established algorithms will leave Anna frustrated. Still, it is not clear that Anna is being irrational. She just changed her mind.In this presentation we investigate cases of preference change in the context of fair division problems; we focus on changes prompted by the belief that someone else can be credited with a particular preference structure. Shifts of this sort give rise to a peculiar regret after acting in agreement with older preferences. We distinguish this phenomenon from other types of regret, and offer new algorithms for fair division that take care of the problem.
