In both the segmented-market Cournot and the integrated-market monopolistic competition settings where these effects have been identified, we show that the only rationale for a trade agreement is to remedy the inefficiency attributable to the terms-of-trade externality, the same rationale that arises in perfectly competitive markets. Furthermore, and again as in the perfectly competitive benchmark case, we show that the principle of reciprocity is efficiency enhancing, as it serves to "undo" the terms-of-trade driven inefficiency that occurs when governments pursue unilateral trade policies. Our results therefore indicate that the terms-of-trade theory of trade agreements applies to a broader set of market structures than previously thought. ER -
