英文摘要：
  How does supply uncertainty affect the structure of supply chain networks? To answer this question we consider a setting where retailers and suppliers must establish a costly relationship with each other prior to engaging in trade. Suppliers, with uncertain yield, announce wholesale prices, while retailers must decide which suppliers to link to based on their wholesale prices. Subsequently, retailers compete with each other in Cournot fashion to sell the acquired supply to consumers. We find that in equilibrium retailers concentrate their links among too few suppliers, i.e., there is insufficient diversification of the supply base. We find that either reduction of supply variance or increase of mean supply, increases a supplier\'s profit. However, these two ways of improving service have qualitatively different effects on welfare: improvement of the expected supply by a supplier makes everyone better off, whereas improvement of supply variance lowers consumer surplus.

中文摘要：
供应不确定性如何影响供应链网络的结构？为了回答这个问题，我们考虑这样一种环境，即零售商和供应商必须在进行贸易之前彼此建立成本高昂的关系。产量不确定的供应商宣布批发价格，而零售商必须根据其批发价格决定与哪些供应商联系。随后，零售商以古诺的方式相互竞争，将获得的供应出售给消费者。我们发现，在均衡状态下，零售商将其联系集中在太少的供应商之间，即供应基础的多样化不足。我们发现，无论是减少供应方差还是增加平均供应，都会增加供应商的利润。然而，这两种改善服务的方式对福利有着质的不同影响：供应商改善预期供应使每个人都过得更好，而供应差异的改善则降低了消费者剩余。
