Supplier credit guarantee loan in supply chain with financial constraint and bargaining

This paper adopts a multiunit bilateral bargaining framework on financial decision. In a two-echelon supply chain, the supplier sells products through a financial constraint retailer. If needed, the retailer gets a short-term financing from a bank by supplier credit guarantee loan (CGL). Through applying the Nash bargaining framework, we formulate two-level game models, i.e. Retailer-Supply System negotiation and Supplier-Bank negotiation. In this paper, we study and discuss the equilibrium order quantity which is affected by initial working capital and interest rate, the retailer-supply system negotiation and upstream wholesale price effects for supply chain performance, the supplier-bank negotiation and interest rate decisions with different capital markets. The results show: (i) there exists loan size limit for financial constraint retailer under CGL. (ii) The upstream wholesale price increase will weaken retailer’s bargaining position, and the supply system may gain or lose depending on the bargaining power. (iii) There exists unique equilibrium sharing ratio in supply system, which means CGL can achieve risk sharing. (iv) Within a supply system, the upstream wholesale price advantage will weaken bank’s profit, whereas supplier may gain or lose depending on his bargaining power.
