Scenario
DC street band, Spread Love, plays regularly on the corner of 15th St. and New York Ave, situated nicely in the heart of DC’s tourist district, near Lafayette Square and the White House. Employees in the nearby offices complain that the band is a nuisance and the noise distracts them from their work. Some offices and conference rooms in the buildings have been rendered unusable due to the noise. Employees have been forced to work wearing headphones or have brought in white-noise machines to drown out the music. The nearby law firm contacted the Secret Service and the DC police. However, the police determined that the band’s performances were legal.
Question
Are the street musicians imposing a negative or positive externality on the law firm and other employees in the area? To people and tourists walking by? To any other group not mentioned here?
Economic theory suggests that in a private market, public goods will be under-produced. Does street music satisfy the characteristics…

Portland is trying to reduce annual NOx emissions by 200 units. Its environmental
planners are now deciding how to allocate the abatement mandate between cars and
power plants. The marginal costs of abatement from cars (Qc) and abatement from
plants (Qp) are MACC = 3Qc and MACP = Qp. Each source is currently emitting 200
units (so total emission from both sources are 400). (Note: Q is the quantity of
abatement and the goal is to abate a total of 200 units).
%3D
(a) On your work sheet Graph the two marginal cost lines (on two separate graphs).
(b) The traditional approach has been to assign all 200 units of abatement to the
power plants, i.e. Qc = 0 and Qp = 200. What is the total cost of abatement under
this system?
Show your calculations on your work sheet and enter the total cost in the blank
below.
(c) The planners have hired you to tell them what the cheapest way is for the city to
divide the 200 units of abatement between the two sources. What do you tell them?
(ie. what are Qc"…

Real estate developer Hysan Group, which owns nine properties in the area, asked the Board to relax the limits, but the Board denied the application. What externality does the height restriction resolve? How would the Hysan Group benefit from relaxing the height restrictions?

The daily costs of the processes and the corresponding number of tons of smoke emitted are as shown in the following table: Process (smoke) Cost to Sludge Oil ($/day) Cost to Northwest Lumber ($/day) The City Council wants to curb emissions by half and decides to auction off four permits, each of which entitles the bearer to emit 1 ton of smoke per day. No smoke may be emitted without a permit. Suppose the government conducts the auction by starting at $1 and asking how many permits each firm wants to buy at that price. If the total is more than four, it then raises the price by $1 and asks again, and so on, until the total quantity of demanded permits falls to four. How much will each permit sell for in this auction? Each permit will sell for $ 3 500 A (4 tons/day) B (3 tons/day) C (2 tons/day) D (1 ton/day) E (8…arrow_forward
