Go to the Internet and find a news article published within the last three months that discusses a potential positive or negative externality and a proposed regulation to deal with it. Summarize key points in your initial discussion post.

Be sure to use the concepts and frameworks we are covering this week. 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?

Note: 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.
