Suppose the government wants to reduce the total pollution e
Suppose the government wants to reduce the total pollution emitted by three local firms. Currently, each firm is creating 4 units of pollution in the area, for a total of 12 pollution units. If the government wants to reduce total pollution in the area to 6 units, it can choose between the following two methods Available Methods to Reduce Pollution 1. The government sets pollution standards using regulation 2. The government allocates tradable pollution permits Each firm faces different costs, so reducing pollution is more difficult for some firms than others. The following table shows the cost each firm faces to eliminate each unit of pollution. For each firm, assume that the cost of reducing pollution to zero (that is, eliminating all 4 units of pollution) is prohibitively expensive Firm Firm X Firm Y Firm Z First Unit of Pollution (Dollars) 130 600 90 Cost of Eliminating the... Second Unit of Pollution (Dollars) 165 750 115 Third Unit of Pollution (Dollars 220 1,200 140 Now, imagine that two government employees proposed alternative plans for reducing pollution by 6 units Method 1: Regulation The first government employee suggests limiting pollution through regulation. To meet the pollution goal, the government requires each firm to reduce its pollution by 2 units
Solution
Ans:
1) The total cost of eliminating two units of pollution.
Firm X = $130 + $165
= $295
Firm Y = $600 + $750
= $1350
Firm Z = $90 + $115
= $205
2) $310,$548
The cost of eliminating third unit of pollution to firm X is $220 and firm Z is $140.when the permit price is above $220, both firms will sell a permit to firm Y.
3) when the permit price is $531, both firm X and firm Z will sell a permit to firm Y.
4) Total cost of eliminating six units of pollution
Regulation = $295 + $1350 + $205
= $1850
Tradable permits = $515 + $345
= $860
5) Less
Eliminating pollution is less costly to society using tradable permits.
| Firm | Initial pollution permit allocation | Action | Final amount of pollution eliminated | Cost of reducing pollution |
| X | 2 | sell one permit | 3 units | $130 + $165 + $220 = $515 |
| Y | 2 | buy two permits | 0 | |
| Z | 2 | sell one permit | 3 units | $90 + $115 + $140 = $345 |
