Suppose the monopolist depicted in Figure 1 is able to practice 1st degree (perfect) price discrimination if it could do this successfully
the total number of units sold and the price of the last unit
sold will be:
Suppose a small town in Northern California has only one restaurant.
Suppose the annual earthquake insurance premiums for that restaurant
increase. Which of the following would we expect in the short-run:
An increase in prices and no change in the number of meals sold.
An increase in prices and a decrease in the number of meals sold.
Again considering the restaurant whose earthquake insurance premiums
rose, which of the following would we expect in the long-run when
compared with the period just before the insurance premiums rose
(if nothing else changes):
An increase in prices and no change in the number of meals sold.
An increase in prices and a decrease in the number of meals sold.
Consider the demand curves shown in Figure 2. If D is the demand curve for a monopolist, which demand curve represents
the one that it will face if a second firm enters the industry.
Again using the demand curves shown in Figure 2, if D is the demand curve for one of two firms in an industry, which
demand curve represents the one that it will face if it is able
to force the other firm to leave the industry by winning a patent
infringement suit against the other firm.
Suppose the diamond industry is a monopoly and suppose that there
is an increase in the productivity of diamond miners. Which of
the following would you predict will happen in the market for
diamonds.
An increase in the price of diamonds and no change in the number
of diamonds sold.
An increase in the price of diamonds and a decrease in the number
of diamonds sold.
No change in the price of diamonds and no change in the number
of diamonds sold.
A decrease in the price of diamonds and no change in the number
of diamonds sold.
Again considering the effect of an increase in the productivity
of diamond miners. Which of the following best describes the profit
experience of the diamond industry as a result.
Publishing companies typically charge libraries higher subscription
rates than individuals for technical journals. (By technical journals
we mean publications where articles are written by experts in
a field for other experts such as the New England Journal of Medicine or the Molecular Biology or the Journal of Public Economics. It is not uncommon to find that rates charged to libraries are
5 or 10 times or even more above those charged to individuals.
The best explanation for the ability of the firms to do this is
that:
When you go to the movies, the theater is a monopoly vendor of
popcorn while you're there (which is why it costs so much). Suppose
that the cost to the theater of fake butter flavoring and yellow
food coloring rise significantly, what will happen to the price
and quantity of popcorn sold by the theater.
The price of popcorn will rise and the quantity sold will increase.
The data in Table 1 above are for Lane, the only vendor of brick oven baked goat
cheese and avocado pizzas at a sporting event. Q is the number of pizzas sold each hour, P is the price in dollars and TR is the total revenue (just P X Q). If the vendor determines that her profit maximizing price per
pizza is $15 then her marginal cost for each pizza must be:
Suppose at the next sporting event, a few weeks later, we observe
Lane (still with the same monopoly on brick oven baked goat cheese
and avocado pizzas) selling her pizzas for $17 each. If nothing
has changed about the demand data we know then that her new marginal
cost for each pizza must be:
