In the market for pharmaceuticals, the issue of "drug loss" illustrates which of the following ideas?
The longer a drug is tested for safety, the lower is the opportunity cost in terms of lives lost.
If a drug is not tested for safety, it might kill more people.

10
/ 10 pts
Recall Chapter 1's opening story about the British sea captains and the convicted felons. In what way were incentives used to solve the problem of the high mortality rate on board the ships?
Payment (to captains) was to be offered for each prisoner that was taken aboard the ships.
Payment (to ship captains) was made independent of the regulations passed for prisoner welfare.
Regulations were passed so that prisoners could get better food, water, and medical
care.
Payment (to ship captains) was made dependent on the survival rate of prisoners.
Question 14

The Edict on Maximum Prices, established by the Roman emperor Diocletian, created price ceilings on various jobs and goods in a failed effort to curb inflation.
For example, legal pay for a farm laborer could be no more that $0.108 a day (payment set in modern currency). If the market rate of farm labor was $0.12 a day, which would be a plausible consequence of this law?
Farms would produce more food than they otherwise would.
Nothing unusual would happen.
A laborer would work less hard than he otherwise would.

1. Suppose you are considering to make a decent holiday dinner. In this year, to be creative, you
are thinking to put Copper River Salmon from Alaska (fillet) and fresh Atlantic Lobsters from
Maine as entrée on the table. Use the information given, to finish the questions below.
(1) The table following provides you total utility (U) and marginal (MU) from consuming
Salmon and Lobster. Suppose your total utility of Salmon consumption (U1) is a function of the
units (Q as pound or lbs.) of salmon consumed, as U1 =.
=/400Q. Similarly, your total utility of
Lobster (U2) has the form as units (Q as lbs.) of lobster consumed, which is U2 = /36Q + 40.

EXERCISE 7
Aisha is considering how to allocate the next 6 hours of her free time. She could choose
between leisure (L) and helping her neighbour with the house chores. If she decides to
help her neighbour, she is going to get paid at £25 per hour, which she can then spend on
her favourite pizza (P). Suppose the price of pizza is £12.50. Aisha's preferences for
leisure and pizza are given by the following utility function: U(L, P) = 3L + P.
(MU₁ = 3, MUp = 1).
a) Write down Aisha's budget equation and draw the corresponding budget line.
Clearly label the axes and calculate the coordinates of the points of intersection of
the budget line with each axis.
b) Calculate Aisha's marginal rate of substitution between leisure and pizza. Explain
the concept of MRS and interpret the figure obtained.
c) Find Aisha's optimal consumption bundle, both algebraically and graphically.
Explain your reasoning.

Imagine there is an outbreak of 'mad sheep' disease, which wipes out a
considerable portion of the sheep population in Scotland. This results in a
shortage of Haggis and an increase in its price.
a) Show the effect of this price increase on Angus' budget line and
optimal choice, and explain the forces underpinning this outcome.
(Hint: Consider substitution and income effects).
b) Assuming that Haggis' price continues to increase over the
subsequent months, derive the demand curve for Haggis.
c) Discuss the income and substitution effects within the context of
this price increase assuming that Haggis is an inferior good.

A consumer finds only three products, X, Y, and Z, are for sale. The amount of utility yielded by their consumption
is shown in the table below. Assume that the prices of X, Y, and Z are $10, $2, and $8, respectively, and that the
consumer has an income of $74 to spend.
(a) Complete the following table by computing the marginal utility per dollar for successive units of X, Y, and Z to
one or two decimal places.
(b) How many units of X, Y, and Z will the consumer buy when maximizing utility and spending all income? Show
this result using the utility maximization formula.
(c) Why would the consumer not be maximizing utility by purchasing 2 units of X, 4 units of Y, and 1 unit of Z?

John likes Coca-Cola. After consuming one Coke, John has a total utility of 10 utils. After two Cokes, he has a total utility of 25 utils. After three Cokes, he has a total utility of 50 utils. Does John show diminishing marginal utility for Coke or does he show increasing marginal utility for Coke? Suppose that John has $3 in his pocket. If Cokes cost $1 each and John is willing to spend one of his dollars on purchasing a first can of Coke, would he spend his second dollar on a Coke, too? What about the third dollar? If John’s marginal utility for Coke keeps on increasing no matter how many Cokes he drinks, would it be fair to say that he is addicted to Coke?

Question 10
Which of the following startements about network externalities is CORRECT?
Air pollution is an example of a network externality.
For a good with network externalities, the number of people who are willing to
buy a unit of the good is uniquely determined by the price.
Network externalities are always positive.
The manufacturer of a new good with network externalities might give away a
free version of the good.
For a good with network externalities, one person's valuation of the good is
always increasing in the number of other people using the good.
