Everytime he sells one of these he has to hand over $5.00 (shifts supply curve up by $5)- So applying a tax is like shifting the supply curve up by the amount of the tax.- Supply curve shifted up, demand curve did not move, what does that mean?- we are going to have a new price and quantity in the market- Pg 117- Three Points to pay attention:- old equilibrium, after we add the tax there is a new equilibrium; however thats not what the seller gets, that’s what the customer pays.- e.g. customer is pay $8 dollars rather than $5 but the seller is going to receive $3- Sample Problem #2- Consider the following supply and demand curve- Original: P = 10+2.3Q and P=34-2Q- Apply a tax shift UP by amount of tax $8 Tax?- P=18+2/3Q and P = 34-2QThese notes represent a detailed interpretation of the professor’s lecture.
