A MORE PERFECT UNION?
This essay was delivered as the Frank D. Graham Memorial Lecture at PrincetonUniversity. Portions of it owe much to my teachers Sheldon Wolin and John Schaar,whose influence it gives me pleasure to acknowledge. Ron Rogowski instructed me onthe literature on legitimacy. Jeffry Frieden’s council clarified my thinking on matterspolitical. Fabio Ghironi generously allowed me to draw on joint work and critiqued myanalysis. Finally, I thank Max Corden for helpful comments; in a sense, this paper is asequel to his Graham Lecture on the same subject.
THE LOGIC OF ECONOMIC INTEGRATION
This lecture is about the connections between three types of union—customs union, monetary union, and political union. The first sectionasks whether monetary integration is a concomitant of commercialintegration.1 The second asks whether political integration is a con-comitant of monetary integration.
I use the ambiguous word “concomitant” to indicate that I am actuallylooking at several questions. One is whether monetary integration mustaccompany commercial integration before efficiency advantages can beobtained from the latter. Another is whether commercial integrationdelivers a larger increase in efficiency and welfare when accompaniedby monetary integration, and whether the welfare improvement frommonetary integration is greater when accompanied by political integra-tion. A third asks what combination of commercial, monetary, andpolitical integration is Pareto optimal. And a fourth, and different,question—concerned with the political equilibrium rather than thesocial optimum—asks whether monetary union is necessary to maintainpolitical support for commercial integration and whether politicalintegration is necessary to assemble support for monetary union.
My answer to the first question is that neither a common currencynor measures to limit the fluctuations of exchange rates are essential toderive efficiency advantages from a customs union, assuming that theunion is “natural”—that the benefits of trade creation dominate the
1 Throughout this lecture, I use the term “commercial integration” to refer tomovement toward the establishment of free-trade areas and customs unions, and“economic integration” to denote more far-reaching initiatives, such as the EuropeanUnion’s effort to establish an integrated internal market both in goods and services andin factors of production.
