内容简介：

We consider two competing firms that order from an external supplier and sell in uncertain markets. The supplier offers a common wholesale-price menu. The firms can either form a cooperative to order from the supplier together (joint sourcing), or unilaterally order from the supplier but obtain stocks from each other on a needed basis (horizontal sourcing). We show that the firms rely on collaborative sourcing, in either form, to mitigate quantity pressure when the supplier offers a low or no discount but save costs otherwise. Joint and horizontal sourcing are strategic substitutes, though joint sourcing is more effective in saving cost and improving market selling. These two strategies are complements as well since the firms have the flexibility in deploying stocks across markets to utilize differential selling opportunities only by horizontal sourcing. Once the firms jointly source, strategic substitutability has them forfeit horizontal sourcing in deterministic markets, but strategic complementarity has them adopt it in volatile markets. Once the firms source from each other, further forming a cooperative to engage in joint sourcing has mixed profit implications. Importantly, sourcing cooperation between firms does not necessarily hurt the supplier, and their increased orders that may result from this strategic move does not necessarily benefit the supplier either. The supplier can tailor the wholesale-price menu to fit the firms’ sourcing strategy and generate a profit gain to every party.
