讲座摘要:

                           

We study a special form of group buying: thegroup buying succeeds if and only if the number of sign-ups reaches a presetthreshold, with no duration constraint. Such type of group buying is oftenadopted for a special edition of the product, offered alongside a constantlyavailable regular product. Customers with heterogeneous valuations arrivesequentially and decide between signing up for the group buying or purchasingthe regular product. To decide on whether to join the group buying, customersneed to anticipate their expected waiting time, which varies depending on thecumulative sign-ups upon their arrival. The firm decides on the prices of thegroup-buying product and regular product, with the product quality levels andgroup-buying size exogenously determined. We show that group buying withflexible duration can result in intertemporal customer segmentation, asdifferent segments might be admitted at different times in the dynamic sign-upprocess. Such intertemporal segmentation has non-trivial implications. First,the loss of efficiency due to waiting for enough sign-ups may decrease in thebatch size required for economic production. Second, as valuation heterogeneityin the market increases, the firm may not always benefit from offering groupbuying along with the regular product. Third, group buying can create a win-win-winsolution for all customers as well as the firm. As extensions, we show thefirm’s profitability can be further improved, by contingently setting prices orconcealing sign-up information in group buying.
