Another Look at Airport Congestion Pricing
比较了美国机场拥堵定价的两种方案：对所有飞机收费，还是只对航空公司给其他公司造成的延误收费。研究发现两者净收益差异很小，因为大部分延误未被内部化，且对内部化拥堵定价的效率损失很小。
We study alternate approaches to implement congestion pricing at US airports. Conventional formulations toll all aircraft without determining whether a plane operated by a given airline delays other planes that it operates or planes operated by other airlines. Recent work points out optimal pricing calls for carriers to be charged only for the delay they impose on other airlines. We find a small difference between the net benefits generated by the two congestion-pricing policies because the bulk of airport delays are not internalized and because the efficiency loss from pricing internalized congestion is small.
