The WTO Dispute Settlement System: First Assessment from an Economic Perspective.

We explore the incentives countries face in trade litigation within the new WTO dispute settlement system. Our analysis yields a number of interesting predictions. First, because sanctions are ruled out during the litigation process, the dispute settlement system does not preclude all new trade restrictions. However, the agenda-setting capacity of the complainant, including its right to force a decision, make trade restrictions less attractive than under the WTO's predecessor, GATT. Second, the system's appellate review provides the losing defendant with strong incentives to delay negative findings, and both parties with a possibility to signal their determinacy in fighting the case. Third, a relatively weak implementation procedure potentially reinforces incentives to violate WTO trade rules. Fourth, bilateral settlements are more likely at an early stage in the process and are biased toward the expected outcome of the formal dispute settlement procedure. Empirical evidence based on a first dataset of cases at an advanced stage of the litigation process provides qualitative support for our claims. Copyright 2000 by Oxford University Press.
