ECO100Y1 Lecture Notes - Lecture 21: Average Cost, Marginal Cost, Average Variable Cost
Document Summary
A tax has been levied on a product. Incidence of a sales tax (who ultimately pays tax, the buyer or the seller?) Assume tax to be paid by seller (remember: incidence does not depend on whether paid by seller or by buyer) Insight: use perfectly inelastic and perfectly elastic demand curves to analyze problem. Answer is d: the lower is the revenue that is raised by the tax. Perfectly inelastic dd: market price increases by amount of tax full incidence falls on buyer. Perfectly elastic dd: market price does not increase full incidence falls on seller: a fir(cid:373)"s (cid:373)argi(cid:374)al cost is , its average total cost is , a(cid:374)d its output is 800 units. Its total cost of producing 801 units is probably: less than ,000, between ,000 and ,050, less than ,000, between ,000 and ,050, greater than ,080.
