When you buy a set of speakers, Best Buy asks if
you would like to purchase insurance for your speakers. Assume that paying for
new speakers for customers who listen to music at a reasonable level (thus
minimizing damage) costs on average $150, and paying for new speakers for
customers who listen to music very loudly (more likely to damage the speakers) costs on average $1000. Individual know
whether they like music at a reasonable level or at a loud level, but Best Buy
can assume that 40% of listeners are reasonable listeners, and 60% are loud
listeners. How much does Best Buy have to charge in order to break even?
a.
$660
b.
$1000
c.
$150

The publisher of an online Economics Primer
course is trying to sell the primer to a group of MBA students and a group of
EMBA students in the US. The maximum willingness to pay for the primer in each
group of students as well as the number of students in each group is given in
the table. Assume the marginal cost is $50. Also, assume the publisher does not
know who is a MBA and who is an EMBA student.

Please
answer all of the following questions.
Chapter 11
Flight to Safety
16)
As stock markets have crashed, and uncertainty has increased, consumers move
their money to the safest currencies and countries in the world. Predict the effects of an increase in
uncertainty on GBP/U.S.dollar exchange rates between 2008 and 2009 assuming
that in September, 2008, the British pound was trading at $1.85 and by January,
2009, it was down to $1.35. Specifically, what happens to demand for dollars
and what happens to the supply of pounds?
Chapter 12
Pricing Commonly Owned Substitute Products
17) Branded drugs face generic entry by rival drugs that
typically take 80% of sales away from the branded drug within three years. This loss occurs because generic drugs are
much cheaper than branded drugs, and most insurance companies won’t pay for a
branded drug if a generic is available.
But in one instance, the branded-drug maker sued the generic entrant for
violating its patent. In the settlement
negotiations that ensued, the branded-drug maker offered to pay the generic
entrant $10 million to settle the patent dispute by staying out of the
industry. Why would the branded drug
offer to pay the generic drug to stay out of the industry?
Chapter 14
Inter-temporal Price
Discrimination
18)
Suppose that technophiles are willing to pay $400 now for the latest iPhone,
but only $300 if they have to wait a year. Normal people are willing to pay
$250, and their desire to purchase does not vary with time. Ignore the time
value of money and compute the optimal pricing scheme of the iPhone. Assume
that there are equal numbers of each customer type, and that the MC of the
iPhone is $100.
Chapter 15
Auditing Game
19) The manager of a
corporate division faces the possibility of an audit every year. She prefers to spend time preparing if she
will be audited; otherwise, she would prefer to invest her time elsewhere. The auditor, who gets recognized for
uncovering problems, prefers to audit unprepared clients. If the players match their actions (i.e., the
manager prepares and the auditor audits, or the manager doesn’t prepare and the
auditor doesn’t audit), the manager wins with a payoff of 20, and the auditor
loses with a payoff of –20. If the
actions don’t match, the auditor wins with a payoff of 20, and the manager
loses with a payoff of –20. Diagram this
game, and comment on the equilibrium.Is there any pure
strategy Nash equilibrium?
Chapter 16
Ultimatum Game
20) You are given an offer to split a $20 bill. The other player offers you $1. If you accept the offer, you keep the $1 and
the other player keeps $19. If you
reject the offer, neither of you will get anything. Do you take the offer? How
could you take the advantage away from the other player in this game?
Chapter 17
Boat Insurance
21) Maritime
Insurance Company offers insurance policies for recreational boats. A typical
policy will pay the replacement cost of $25,000 if the boat is a total loss. If
the boat is not a total loss but the damage is more than $10,000, the policy
pays $5,000. For damage under $10,000, no coverage is offered. The company
estimates the probability of no damage to be 0.60, the probability of damage
between $0 and $10,000 to be 0.25, and the probability of damage between
$10,000 and $25,000 to be 0.12. If the company wants to make a profit of $200
above the expected cost, what should be the price of the policy?
Chapter 18
Two-Bidder Auction
22) You hold
an auction on eBay and expect two bidders to show up. You estimate that each
bidder has a value of either $5 or $8 for the item, and you attach
probabilities to each value of 50%. Your own value for the item is zero. You
can set a reserve price, a price below which you will not accept bids for the
item. What reserve price should you set, and what is your expected revenue from
auctioning the item with a reserve price?
Chapter 19
“Soft Selling” and Adverse Selection
23) Soft selling occurs when a buyer is skeptical of the
quality or usefulness of a product or service.
For example, suppose you’re trying to sell a company a new accounting
system that will reduce costs by 10%.
Instead of asking for a price, you offer to give them the product in
exchange for 50% of their cost savings.
Describe the information asymmetry, the adverse selection problem, and
why soft selling is a successful signal.

Business Loan
24) A colleague tells you that he can get a business loan

low-risk loan.
a)
Give an adverse selection explanation for this,
and offer advice to your friend on how to solve the problem (how to lower the
rate).
b)
Give a moral hazard explanation for this, and
offer advice to your friend on how to solve the problem (how to lower the
rate).
