I come up with a thought that if there is any difference in term of imposing a tax to consumer or producer, I searched for the answer and there is some logic messing up..
let Pd be the consumer price; and Ps be the producer price Suppose the Unit Tax imposes to consumer, so in equilibrium: Pd=Ps+t since the consumer now is paying extra t dollars than the producer receive.
On the other hand, Suppose the unit tax imposes to producer, so in equilibrium: Ps+t=Pd since the producer now is paying extra t than its originally pay
Now the question is, why two formulas are identical? So is there any difference impose unit tax in terms of consumer or producer? ...or I did something wrong with my logic?
Thanks!
