Frank Vibert's book, Europe: A Constitution for the Millennium, draws on constitutional economics to describe how aEuropean constitution should be developed to govern aEuropean political union. Vibert's theoretical constitutional framework is solid, but his analysis has two shortcomings. First, he discusses constitutional theory but never presents any specific constitutional provisions that would be based on that theory. This makes the feasibility of drawing up an acceptable constitution appear more straightforward than it actually is. Second, he assumes that Europe will eventually be politically unified in much the same manner as the United States, and does not consider alternatives. Rather than having a single European government, as Vibert suggests, a better alternative would be to have European nations united through a variety of treaties, agreements, and multinational organizations.
