Jurisdictional integration: A framework for measuring and predicting the depth of international regulatory cooperation in competition policy

This article takes a new approach to international regulatory cooperation by developing a concept of the depth of cooperation, jurisdictional integration. A dataset of international competition policy agreements is compiled and ranked against an ordinal index of the depth of de jure cooperation in enforcing competition policies. There has been both a deepening and broadening of de jure cooperation over time. Statistical analysis finds that common membership of the O rganisation for E conomic C o‐operation and D evelopment is a strong predictor of the depth of agreements to cooperate in enforcing competition policies; that we can be confident that the depth of agreements is low when signatories' substantive competition laws are dissimilar; and that the depth of de jure cooperation is a strong predictor of whether an agreement is “intergovernmental” or “transgovernmental.” The article puts forward a new way to map and measure international regulatory cooperation, and a new variable for use in research on its causes and consequences.
