Suppose there are two ways to reduce water pollution in a river. Society needs to remove 150 units of pollution (q). The marginal cost of the first method is 2q1. The marginal cost of the second method is 3q2. Society wants to use the most cost-effective way to reduce water pollution. How many units of pollution should be removed using the second method? (Round your answer to two decimal places.

Solutions

Expert Solution

MC1= 2q1, MC2= 3q2

q1+ q2= 150

So, at cost effective solution

MC1= MC2

2q1= 3q2

Put q1= 150-q2

So, 2(150-q2) = 3q2

300-2q2= 3q2

300= 5q2

q2*= 60

If society wishes to reduce pollution, why is it more efficient to tax the pollution rather than set a limit on pollution? If the government issues tradeable pollution permits (ie., a cap-and-trade policy), does it matter for economic efficiency (social welfare) whether all firms receive the same amount of permits, or whether some firms receive more permits than others?

Suppose a pulp and paper mill emits pollution into a river upstream of a commercial fishing operation. The emissions from the mill damage the fishery by reducing the number of fish that can be caught. The mill benefits from emissions as these are a by-product of pulp and paper production. Explain why the pollution level under point (b) is not an efficient outcome.   What is the efficient level of pollution? Explain.

Producing an industrial good causes pollution to a river. Previously, farmers had used water from the river to irrigate their fields. Which of the following statements about this externality is not correct? (a) In the absence of well-defined property rights, the free-market equilibrium will be inefficient. (b) The distortion caused by this externality can be corrected using a tax on the output of the industrial good. (c) If property rights are fully defined, and markets are complete with no transaction...

A wastewater plant needs to reduce the methane content in water in a stripping tower to 0.3 mol %. The liquid stream is entering the tower with a flow rate of 200 mole/h and contains 0.8 mol % methane. The tower uses pure air for stripping and its temperature and pressure are held constant at 300 K and 1 atm, respectively. The equilibrium relation for methane in the air-water system is ? = 1.2?. a) Find the minimum vapor flow...

Suppose China wishes to reduce the amount of air pollution generated by electrical plants. The marginal benefit of electricity is P = 464, 000 − 200Q and the producers’ marginal cost is P = 32, 000 + 70Q. The air pollution presents a negative externality and the marginal external cost of each unit is P = 75.6Q. 1. In the market equilibrium, what is the total cost of the pollution externality? 2. In the socially optimal outcome, what is the...
