Explorations in aggregating choices
A choice is understood as any function which picks a subset from each set of alternatives. Such choices are aggregated here in four different ways: through composition, choice-union and two procedures inspired by game- theoretic solution concepts, namely the non-cooperative and the von Stackelberg. In each case we are interested in the extent to which certain well-known choice-theoretic properties are preserved by the aggregation studied. In closing, we regard certain algebraic aspects of aggregations and means of choices, remarking on their ethical implications.
