Is a production quota Pareto superior to price support only?
在一般均衡框架下证明，配额加关税政策下的效用水平高于仅有关税的情况，但低于无价格扭曲的情况。
This note shows, using a general equilibrium framework, that the level of utility attainable under a quota-cum-tariff policy is higher than in the tariff-alone case but, as should be expected, lower than without any price distortion
