Consider the market for electricity. Suppose demand (in megawatt hours) is given by? = 40 _ P and that the marginal private cost of generating electricity is 10 per megawatt hour ( is in the same units). Suppose further that toxic smoke is generated in the production of electricity. Thereby, one megawatt hour of electricity corresponds to one unit of smoke. The health damage for society from one unit of smoke is 2 per megawatt hour generated. Suppose the electricity is produced by perfectly competitive producers 1. What price will be charged, and how much electricity will be produced
