Article summary
This article asks whether variation across human rights treaties in the scope and demandingness of obligations influences states’ decisions to ratify. The authors argue that treaties differ in the number and severity of obligations they impose, that this variation can be measured, and that it affects ratification choices. Using newly compiled data on obligations and commitments across the 10 core global human rights treaties, the article tests whether treaties with more demanding obligations are less likely to be ratified by states that would face higher compliance costs.
