The External Reality

Here is a comprehensive review of positive and negative externalities. It includes the difference between marginal social cost and marginal private cost as well as the difference between marginal social benefit and marginal private benefit. Again there is no review activity for this one, but I’ll start making more of those after I make a few more Microeconomics content review articles.
