Assume that the supply of a best-selling book at local book stores throughout the United States is a function price such that:
Q5=-5+5P (Supply)
Where Q is the number of books sold (in thousands) and P is the book price. Given tha availability of this book on amazon.com for $20, demand is perfectly elastic at a price of $20.
Derive the second book supply curve based upon the assumption local sales are subject to an 8% sales tax that is not imposed on internet sales. Calculate the book price and quantity effects of the local 8% sales tax. With perfectly elastic demand, who pays the economic burden of such a tax?
