The Use of Economics in WTO Appellate Body Decisions


  • Thomas J. Prusa


While WTO disputes involve legal rights and obligations, economics often can help the Appellate Body (AB) make sense of the dispute and the implications of ambiguous language in the Agreements. This paper reviews three examples of where the economics could have provided a clearer basis for the AB’s decision. I begin by looking at the question of whether countervailing duties can continue to be imposed subsequent to privatization of state-owned enterprises. I next review the question of how antidumping margins are calculated and whether the zeroing methodology is consistent with the fair comparison requirement. Finally, I examine the question of whether the simultaneous application of antidumping and countervailing duties on imports from non-market economies constitutes double remedy. In each of these examples I argue that standard economic theory provides the basis for clear and logic interpretation of the relevant WTO provisions.
