The Rock and Roll Hall of Fame has asked you, a world-renowned music critic, to analyze the market for guitars. Suppose demand for guitars is a function of the price of guitars, P, and the price of hand massages, Ph. Hand massages are a complement to guitars since lots of playing makes hands very sore. The supply of guitar is a function only of the price of guitars, P. a. The Rock and Roll Hall of Fame wants to know how the market equilibrium price and quantity of guitars, P* and Q*, will be impacted if there is a decrease in the price of hand massages Ph. Use a diagram for the market for guitars, assuming downward sloping demand and upward sloping supply, to provide an answer, and explain why the answer makes sense using the concept of complementary goods. b. The Rock and Roll Hall of Fame is worried your answer concerning the impact on price might be wrong because it does not precisely measure the demand and supply functions for guitars. Use the most general forms of the demand and supply functions (Qa = D(P, Ph) & Qs = S(P) ) and calculus, to demonstrate that you do not need to know the exact functions. Show that your predictions for equilibrium price will be correct as long as demand for guitars slopes down, and supply slopes up, assuming a massage is a complementary good with respect to guitars. Use calculus to show that your prediction for equilibrium quantity holds under the same assumptions needed in the previous part. C.

Suppose that the table on the right shows the quantity demanded of UGG boots at five different prices in 2014 and in 2015. Which of the following variables could cause the quantity demanded of UGG boots to change as indicated from 2014 to 2015? (Check all that apply.) A. An increase in the price of UGG boots B. A decrease in the price of a substitute good C. A decrease in the number of buyers D. The expectation that UGG boots will rise in price Price $160 170 180 190 200 Quantity Demanded 2014 5000 4500 4000 3500 3000 Quantity Demanded 2015 4000 3500 3000 2500 2000
