Abstract

We prove that the normalization rule in Bond and Syropoulos (1996, Journal of International Economics 40, 411-437) that sets the world price of good 1 as the numéraire causes asymmetry in the Nash equilibrium. Such rule contradicts their symmetric assumption when one derives other blocs' optimum tariffs from their viewpoints. We further show that under symmetry their results are consistent only in the case of two trading blocs.

Keywords: Trading Blocs; Strategic Interactions; Normalization Problem; Nash Symmetric Game
