Gains from Trade in a Differential Game Model of Asymmetric Oligopoly

This paper revisits a classical topic of trade gains in a differential game model of oligopoly in which Home and Foreign firms differ in the number and cost. After deriving the feedback Nash equilibrium, we provide examples to consider how the difference in the number of firms or costs affects gainfulness of trade. We prove that feedback strategies can result in implications for trade gains which are sharply different from the open-loop case. Copyright © 2009 The Author.
