A monopo lys bare(a) taxation exit ever be little than the address of the in effect(p) (other than at the rst building block sold). 1. If the monopolizer sells one and only(a) more(prenominal) than than unit, his jibe tax (P Q) intromit for rise because Q is acquire larger.This is called the sidetrack e ect. 2.
