Sovereignty Relinquished? Explaining Commitment to the International Human Rights Covenants, 1966-1999

Abstract

This article examines whether the content of the International Human Rights Covenants and the costs associated with their ratification influence the decision of countries to join. The author evaluates three theoretical perspectives-rationalism, world polity institutionalism, and the clash of civilizations-with data for more than 130 countries between 1966 and 1999. Rationalists contend that treaty ratification is tightly coupled with internal sovereignty arrangements, human rights practices, and ideological commitments, all of which become more important as treaty enforcement strengthens. World polity institutionalists expect ratification to be loosely coupled with a country's conduct or its political, ideological, or cultural commitments, although this gap narrows as compliance is more effectively enforced. A civilizations approach predicts tight coupling between ratification and cultural values, regardless of the mechanisms in place for enforcing compliance. Results lend partial support to rationalism and world polity theory, whereas the clash of civilizations thesis is much less successful in accounting for patterns of ratification. Furthermore, the costs of ratifying a treaty, considered in terms of its surveillance and enforcement provisions, influence rates of accession more than the specific rights a treaty protects.
