• 1: The Mexican Challenge 2: The Formalist and Anti-Formalist Approaches to Constitutional Rigidity 3: The Economy of Constitutional Change 4: Political Parties and Formal Constitutional Change in Contemporary Mexico 5: Constitutional Change and Constitutional Culture in Mexico 6: Actors, Choices, Decisions, and the Formation of Political Norms 7: The Supreme Court in Mexico's Economy of Constitutional Change 8: Conclusion

Using the Mexican case, this interdisciplinary volume tackles the question of what makes a constitution difficult to amend. It proposes a new framework for understanding the interaction of formal and informal factors in producing constitutional amendments within an 'economy of change.' The book illustrates the virtue of taking a broad interdisciplinary approach to constitutional studies, producing fresh insights with clarity and rigor. It will now become a standard reference in the understanding of constitutional amendment.
