Go to the Internet and find anewsarticlepublished within the last three monthsthat discusses a potential positive or negative externality and a proposed regulation to deal with it. What externality is this regulation attempting to address? Is it a positive or negative externality? How effective does the current policy appear to be? Is there an alternative policy approach that may work better/worse (taxes or subsidies, for example) and why? Focus on the "third party" effects of increasing a positive externality or decreasing a negative externality - not, for example, on any "third party" financial effects of collecting a tax or of spending the revenue generated by the tax. Also note that if increasing or decreasing spending results in increased or decreased incomes of third parties, this is a "multiplier effect" (an ECON 201 subject) -- not an example of an externality.
