One of Chicago’s Best Ideas was the Coase Theorem, which reminds us daily that people can bargain around law or even before legal intervention is sought. But do we have too much law and too little bargaining around it? The number of cases and judges has grown dramatically over time and many problems are outsourced to the legal system, rather than being handled person-to-person. In this talk, I will consider conventional explanations for the astonishing growth of the legal system, and then suggest that it is not entirely good news. We have become addicted to law, and like most addictions, this one is difficult to undo and likely to grow. Saul Levmore is William B. Graham Distinguished Service Professor of Law. This Chicago's Best Ideas talk was presented on November 5, 2019.
