The literature has shown that supply chain performance is affected by the allocation of inventory risk. Traditionally, a pull supply chain generates a higher optimal order quantity and hence higher supply chain profit than a push supply chain when firms are risk neutral. Extended from the classic push and pull newsvendor models, this paper investigates the impact of firms’ risk averse attitudes on supply chain performance. Based on firms’ Conditional Value-at-Risk (CVaR), our analysis indicates that push can lead to a higher optimal order quantity than pull when the supplier is sufficiently more risk averse than the retailer. Meanwhile, pull contracts cannot always survive push challenge like in risk-neutral supply chain. We demonstrate that three-part traffic revenue sharing contracts can coordinate both the push and the pull supply chains to achieve the Pareto optimality maximizing combined supply chain CVaR.
