The topic of this Essay is not one Terry Sandalow has worked on, but he got me started on it by organizing, with Eric Stein, the Bellagio Conference on comparative constitutional economic integration in the United States and the European Community. For that, and for thirty-three years during which he has been an unfailingly stimulating and supportive colleague, Dean, and friend, I am deeply grateful.
