The tragedy of the commons refers to situations where common resources are subject to overuse and pollution.Examples include forest land,pasture land,fish in the ocean,lions in the wild,shrimp population in the gulf states,a public library,and space on a public beach.Common resources are subject to overuse because each individual captures the private benefit fully but only bears part of the cost of using the resource.As a result,each individual has no incentive to maintain the quality or purity of the resource.

Figure 5-4 Figure 5-4   Suppose there are several paper mills producing paper for a market. These mills, located upstream from a fishing village, discharge a large amount of wastewater into the river. The waste material affects the number of fish in the river, and the use of the river for recreation and as a public water supply source. Figure 5-4 shows the paper market. Use this Figure to answer the following question(s). -Refer to Figure 5-4.What does S<sub>2</sub> represent? Suppose there are several paper mills producing paper for a market.

Figure 5-16 Figure 5-16   Amit and Bree are the only two homeowners on an isolated private road. Both agree that installing street lights along the road would be beneficial and want to do so. Figure 5-16 shows their willingness to pay for different quantities of street lights, the market demand for street lights and the marginal cost of installing the street lights. -Refer to Figure 5-16.What is the optimal quantity of street lights to install?
