a. What are the equilibrium price and quantity of Frisbees?

b. Frisbee manufacturers persuade the government that Frisbee production improves scientists' understanding of aerodynamics and thus is important for national security. A concerned Congress votes to impose a price floor $2 above the equilibrium price. What is the new market price? How many Frisbees are sold?

Q2. Briefly explain whether each of the following statements describes a change in supply or a change in the quantity supplied:

a) To take advantage of high prices for snow shovels during a snowy winter, Alexander Shovels, Inc. decides to increase outputs.

b) The success of Apple iPad leads more firms to begin producing tablet computers.

c) In the six months following the Japanese earthquake and tsunami in 2011, production of automobile in Japan declined by 20 percent.

Q3. As oil prices rose during 2006, the demand for alternative fuels increased. Ethanol, one alternative fuel, is made from corn. According to an article in the Wall Street Journal, the price of tortillas, which are made from corn, also rose during 2006: "The price spike (in tortillas) is part of a ripple effect from the ethanol boom".

a. Draw a demand and supply graph for the corn market and use it to show the effect on this market of an increase in the demand for ethanol. Be sure to indicate the equilibrium price and quantity before and after the increase in the demand for ethanol.

b. Draw a demand and supply graph for the tortilla market and use it to show the effect of this market of an increase in the price of corn. Once again be sure to indicate the equilibrium price and quantity before and after the increase in the demand for ethanol.

Q4. Suppose that Bill owns an automobile collision repair shop. The table below shows how the quantity of cars Bill can repair per month depends on the number of works that he hires. Assume that he pays each worker $4,000 per month and his fixed cost is $6,000 per month.

a. If the current equilibrium price in the earrings market is $1.80, how many earrings will Frances produce, what price she will she charge and how much profit (or loss) will she make? (Hint: you need first to determine the fixed cost from the data provided).  Draw a graph to illustrate your answer. Your graph should be clearly labeled and should include Frances's demand, ATC, AVC, MC and MR curves; the price she is charging, the quantity she is producing and the area representing her profit (or loss).

b. Suppose the equilibrium price of earrings falls to $1.00. Now how many earrings will Frances produce?

b. If Paul wants to maximize profits, what price should he changes and how many baseballs should he sell? Draw a graph to illustrate your answer.

Q8. Suppose you decide to open a copy store. You rent a store (sign a one year lease to do so), and you take out a loan at a local bank and use the money to purchase 10 copiers. Six months later, a large chain opens a copy store two blocks away from yours. As a result, the revenue you receive from your copy store, while sufficient to cover the wage of your employees and the costs of paper and utilities, doesn't cover all your fixed costs (rent and the interest and repayment costs on the loan you took to purchase the copiers). Should you continue operating your business?
