A village has six residents, each of whom has accumulated savings of $100. Each villager can use this money either to
buy a government bond that pays 18 percent interest per year or to buy a year-old llama, send it onto the commons to
graze, and sell it after 1 year. The price the villager gets for the 2-year-old llama depends on the quality of the fleece It
grows while grazing on the commons. That in turn depends on the animal's access to grazing, which depends on the
number of llamas sent to the commons, as shown in the following table:

Suppose that a power plant dumps byproducts into a nearby river, creating a negative externality for those living downstream from the plant. Producing additional electricity imposes a constant per-unit external cost of $490. The following graph shows the demand (private value) curve and the supply (private cost) curve for electricity. Use the purple points (diamond symbol) to plot the social cost curve when the external cost is $490 per unit.
