【摘要】We must assign n agents to m posts subject to negative congestion. If congestion is anonymous (each agent adds one unit) a canonical test of ex ante fairness guarantees to everyone one of their top n out of n × m feasible allocations. We call an assignment competitive if, taking the congestion at each post as given, everyone is assigned to one of their best posts. If it exists the competitive assignment is unique, efficient and ex ante fair. Randomising the assignment under cardinal vNM utilities ensures that every problem has a unique competitive congestion profile, implemented by a mixture of deterministic assignments rounding up or down the competitive congestion, and approximately ex ante fair, efficient and welfare equivalent. If congestion is weighted (agent-specific) ex ante fairness still guarantees an allocation in the top (1/m) quantile of feasible allocations, and under randomisation competitiveness is still an operational solution concept.
