International Negotiation (Vol. 25, no. 2, 2020) Bargaining Power at the Negotiation Table and Beyond

International treaties require ratification to go into effect. But while some treaties have high ratification rates, many do not, leading to a system where issues appear to be addressed on paper but are not in practice. This article seeks to address why treaties receive varying levels of support and finds that factors present during the negotiation phase of the agreement affect the ratification phase. Specifically, bargaining power at and away from the negotiation table influences both the substantive nature of the treaty and the extent to which it will be widely ratifiable. This article explores this issue both in a statistical analysis and in two pairs of qualitative case studies. The evidence indicates that negotiation processes cast a long shadow on the fate of international agreements leading to the current treaty system of prolific international law that is not ratified by most states.
