b. Suppose the council increases the value of a life to $7.2 million. How
does the value placed on a life influence the council’s budget
allocation? Explain briefly.
Discussion Question In the aftermath of the September 11 terrorist attacks
in New York City and Washington, D.C., there has been renewed concern
about airport security. To date, security services at major airports have been
provided by a small number of private firms under contract with the airlines.
a. Many commentators and policy makers have argued that airport security
should not be left as the responsibility of private firms. Identify the
possible sources of market failure (if any) that might lead to security
standards that are too weak. What kinds of economic information could
one gather as evidence for or against market failure?
b. Supposing that a strong case for market failure were made, what are the
possible remedies? How could one apply benefit-cost analysis to craft the
most effective remedy? In answering questions (a) and (b), a first step is
to gather relevant information concerning the economics of airport
security from the business press and online.
Spreadsheet Problem
S1. Consider once again the combination of market failures outlined in
Problem 3. Recall that the demand for wood pulp is described by P
500 10Q, where Q is measured in thousands of units. The long-run
cost of production exhibits constant returns to scale: LAC LMC 150.
Producing a unit of wood pulp generates one unit of pollution, and the
marginal external cost is estimated to be 100 per extra unit of pollution.
a. Create a spreadsheet similar to the one shown to model this setting.
In the spreadsheet, cells B10, C10, and D10 contain numerical values.
The entries in rows 15 and 19 and cell E10 are computed by formulas
linked to the numerical cells. Hints:Remember that consumer surplus
is found by using the formula for the area of a triangle, in this case:
.5*(500-E10)*B10. Total benefit is the sum of consumer surplus, net
profit, and government tax revenue minus the external costs
associated with pollution.
b. Using the spreadsheet, confirm the output and price results for each
of the analyst’s recommendations in Problem 3. Then find the
optimal regulatory policy using the spreadsheet’s optimizer. That is,
maximize total benefit by adjusting the output and tax cells.
c. Now suppose that the wood pulp producers can clean up part or all of
their pollution at a cost. The total cost of cleaning up u units of
pollution is 5u^2 ; that is, it increases quadratically. By cleaning up
pollution, producers avoid any tax. Thus, the government’s tax
