Professor Baker presents a fundamentally unique question. Including all of the legal opinions, statutes and administrative rules, how much law do we have? Is there way to calculate a “Gross Legal Product” for the United States and what effect does this “GLP” have on the U.S. economy? What about all of the secondary legal sources? What do they add, if anything, to our ability to understand all of the law that is constantly being produced? All these and more are the subject of Professor Baker’s article.
