A long debate continues whether international trade institutions (specifically preferential trade agreements, (PTAs)) affect security relations between states. Contradicting theories and empirical claims are put forward by realists and liberals. The former posit that the institutions are epiphenomenal and possess no power to constrain state behavior whereas the latter claim that the institutions are likely to promote cooperation by supplying forums for consultation, arbitration and adjudication, thus reducing the risk of war between states. This study identifies an important channel through which the legal dimension of trade agreements (hence Dispute Settlement Mechanisms in PTAs) may have pacifying effects on the outbreaks of war. Dispute Settlement Mechanisms of PTAs do have strong implications for MIDs, although not directly, but through low-level of foreign policy disputes, such as economic sanctions. If economic sanctions are believed to escalate to violent conflict, PTA DSMs may reduce the probability of war by mitigating the escalation of economic sanctions. However, the level of legalism differs among DSMs in PTAs. The present study first confirms empirically that sanction disputes escalate to militarized disputes and further, addresses the selection issue by using bivariate probit model. I find a sizeable impact of medium level of legalism reducing the sanctions escalation into war whereas high level of legalism, in which the state sovereignty is limited, do reduce the probability of sanctions but have no impact on war probability. Further, the interstate political cooperation proves to be a strong determinant for highly legalistic PTAs but not in the case of medium level of legalism.
