Chapter 2, Problem 45P
A hot water leak in one of the faucets of your apartment can be very wasteful. A continuous leak of one quart per hour (a “slow” leak) at 155°F causes a loss of 1.75 million Btu per year. Suppose your water is heated with electricity.
- a. How many pounds of coat delivered to your electric utility does this leak equate to if one pound of coal contains 12,000 Btu and the boiler combustion process and water distribution system have an overall efficiency of 30%?
- b. If a pound of coat produces 1.83 pounds of CO2 during the combustion process, how much extra carbon dioxide does the leaky faucet produce in a year?

An electric power distributor charges residential customers $0.10 perkilowatt-hour (kWh). The company advertises that “green power” is available in 150 kWh blocks for an additional $4 per month. (Green power is generated from solar, wind power, and methane sources). Solve, a. If a certain customer uses an average of 400 kWh per month and commits to one monthly 150 kWh block of green power, what is her annual power bill? b. What is the average cost per kWh with green power during the year? c. Why does green power cost more than conventional power?
A diesel refinery is upstream of an industrial farm. The runoff from the refinery pollutes the river and damages the crops. The farm earns $499 using the polluted water, but would earn $628 if it were clean. The refinery earns
$1772 but would only earn $1607 if it had to divert resources to prevent the runoff. There are no environmental laws. Assume that a scrubbing machine that would prevent the runoff costs $24 plus an installation cost. What
is the most that installation could cost for clean water to be the socially optimal outcome achieved through private bargaining?
O a. $141.00
O b. $36.00
O c. Anything, the machine is not required as clean water will already be achieved.
O d. $105.00
O e. $165

There are 2000 people uniformly spread along Via Cantonale, and every day they each buy a Pizza from one of the two stores located at either and of the street. Customers ride their motor scooters to and from the store. Travelling the whole town once back and forth costs a customer 10 CHF. Customers buy their Pizza from the store offering at the lowest cost, which is the store's price plus the customer's travel expenses getting to and from the store. Customers' valuation of a Pizza is 30 CHF. Ben owns the store at the west and of Via Cantonale and Will owns the store at the east end of Via Cantonale. The marginal cost of a Pizza is constant and equal to c₁ = 6 CHF for Ben and equal to c₂ = 3 CHF for Will. In addition, each of them incurs a fixed cost of 2500 CHF per day. a) Suppose that Ben and Wil compete in prices and set prices simultaneously (i.e. assume Bertrand competition).
