Similar to welfare economics where with(out) interpersonal comparisons one defines unique (set-valued) welfare (Pareto) optima, we present a framework for one-person decision making where with(out) a prior probability distribution individual optimality prescribes usually a unique (set of)...

Different evaluators typically disagree how to rank different candidates since theycare more or less for the various qualities of the candidates. It is assumed that allevaluators submit vector bids assigning a monetary bid for each possible rank order.The rules must specify for all possible...
