1. Why do you suppose that some observers have called for requiring installation of devices that would enable governments to monitor households' energy consumption?
2. Who ultimately pays to address costs of negative, externalities created by government agencies such as the EPA when they accidentally release pollutants into the environment?
3. Why might allowing profit-maximizing firms to manage the hunting of particular endangered animals potentially help to ensure the animals' species would not disappear? (Would a company continue to generate profits from selling hunting rights if it allowed hunters to kill all of the animals that it manages?)
