Go to the internet and find a news article posted within the last month that discusses a potential positive or negative externality. Summarize key points in your initial discussion post. Address what externality this regulation attempting to address? Is it a positive or negative externality? What is the current policy being used? Is there an alternative policy approach that may work better/worse (taxes or subsidies, for example) and why? How effective does the current policy appear to be working? The article should be from an on-line newspaper or magazine. Materials posted on educational websites, like www.thebalance.com, www.khanacademy.org , and so on, are not considered news articles even if they were recently updated and contain material related to the discussion topic.
