Identify a real-world (in the United States or in another country) situation in which markets do NOT produce a socially-desirable level of output, which means (of course) that production/output does NOT occur at the point where Marginal Benefits (MB) = Marginal Costs (MC).Describe the circumstances that led to that market failure, identify/describe any related (positive or negative) externalities, and clearly state WHAT groups of people or entities are impacted by the(se) externality(ies) and HOW these groups of people or entities are impacted (positively or adversely).Explain how you would propose correcting the market failure you've identified (in other words, how you propose increasing or reducing output such that the level of output moves closer to MB=MC).If you have trouble coming up with an example, consider what comes out of your mouth when you say, "there is too much (or too little) ________ in this world,"
