Group buying decisions of competing retailers with emergency procurement

Group buying has been in vogue for many years, particularly for short-life-cycle products. This paper investigates the effects of pricing and ordering in group buying, and considers the joint decision on pricing and ordering of short-life-cycle products in competing markets if retailers could provide the emergency procurement to meet all stochastic demands. It is shown that retailers always prefer to launch group buying in a single channel, which is also observed in a dual channel for competing retailers due to emergency procurement. These findings differ from those presented in the related literatures.
