One of the most striking changes since I have been a law professor is the rise in the number of legal articles written jointly. This increase in collaboration is of more than academic interest because the reasons for it are leading to greater collaboration in other areas, too. The result will be greater prosperity and human flourishing.
First, joint authorship has grown with interdisciplinary scholarship. Increasingly, law is the subject of inquiry in other disciplines – economics, political science and psychology prominent among them. But those with expertise in these areas frequently lack institutional knowledge of and practical experience in law. They can strengthen their arguments by partnering with law professors more sophistication about these matters, who, in turn get the advantage of more disciplined frameworks of social science. We see the same phenomenon in public policy, where different kinds of knowledge are more regularly pooled, resulting in a fuller, less one-dimensional view of the world.
Second, many law professors also team up in their research, even if neither have interdisciplinary backgrounds. The modern legal academy is marked by increased competition for both students and faculty. Standards for productivity and quality have clearly risen even in my two decades in the businesses. One way of competing better is to combine forces.
