Strategic delegation analysis has been limited to sales delegation cases, untilJansen et al. (International Journal of Industrial Organization 25:531–539, 2007) presentedthe case of market share delegation.

This paper assesses the influenceupon optimal trade policy of introducing market share delegation in a trade duopolycontext. It shows that delegation matters, and different forms of delegation coupled withasymmetric costs will imply different degrees of government intervention.
