The perfectly competitive golfball industry consists of 100 golfball-producing firms with the short-run total cost function ST C=q2+ 20q+ 200−N, where q represents the number of pallets of golfballs produced per day and N represents the number of firms in the industry. Firm marginal cost function is M C= 2q+ 20.

- Find the long-run equilibrium price of a pallet of golfballs, the number of pallets produced by each firm in equilibrium, firm profit, and the market quantity of pallets bought and sold in equilibrium.

- Suppose that the price of golf clubs, a complementary good, decreases, causing a demand increase in the golfball market. Suppose 19 new firms enter the industry in the long run,and that the market subsequently returns to long-run equilibrium. Find the new long-run market equilibrium price and quantity, and the number of pallets produced by each firm. How much profit do firms earn?

Two shops A and B attract two types of customers: price-sensitive customers, who shop at the lower-priced shop, and time-sensitive customers, who shop at whichever shop is on their side of the street. A customer of either type purchases on average 10 goods. Assume there are 800 price-sensitive customers and 500 time-sensitive customers buying goods on any given day. The wholesale price the shop pay per good is $3. For simplicity, assume that they can charge $3.50, $4.00, or $4.50 per good.

The U.S. has placed a 200% tariff on airplanes produced by Bombardier, a Canadian company, after Boeing complained that Bombardier was able to sell their planes to Delta Airlines (an American company) at a lower price. How is Boeing affected by this tariff? How is Delta Airlines affected by this tariff? How is the U.S. government affected? Is the U.S. better off or worse off?

1. Recall that aggregate demand AD is determined by all of the components of desired aggregate expenditure.

COVID-19 has caused the global economic landscape to change very quickly. Furthermore, an oil price war involving Saudi Arabia and Russia has resulted in a dramatic decline in oil prices.

1. [1 point per row] For each of the events below, state which component(s) of aggregate demand is affected, provide a brief explanation, and whether the effect is an increase or decrease. The first is done as an example.

1. Based on the size and direction of the effects above, do you think that overall desired aggregate expenditure has increased or decreased? Would this result in a leftward or rightward shift in the AD curve?

As a budding entrepreneur, you have purchased a small bagel shop. You have engaged in a market study to categorize your customers’ willingness to pay for a meal (coffee+bagel) into 8 equal sized groups: ($5.00, $4.50, $4.00, $3.50, $3.00, $2.50, $2.00, $1.50). All of your costs are fixed except labor and materials, which cost $2.25 per meal sold.

a) What price should you charge for a meal? (Hint: you don’t need to know the number of customers to answer this or part b)

b) Suppose your market research tells you that the four lowest value groups are all students. Should you offer a student discount? If so, how much?

c) If there are 100 daily customers from each consumer group, what is your shop’s profit gain from offering a discount to students relative to offering the same price to all customers?

d) If the fixed costs associated with the shop are salaries, a franchise fee, and rent, which are renewed and paid annually and average $500 per day, should the shop stay open in the long run? Does your answer depend on whether or not the shop offers a student discount?
