Based on the asymmetric sale price information, the interactions of operational and financing decision problems are studied in the supply chain, where a capital-constraint retailer borrows from the capital market to get the optimal ordering. With the Stackelberg game, the pooling contract and the screening contract are modeled under asymmetric information. The conclusions indicate that the screening contract is more helpful to motivate retailers to tell the private information and also to increase the profit of the whole supply chain than the pooling contract. The commercial bank prefers the retailer with higher
price to reduce the credit risks. The screening model brings more profit to the bank than the pooling contract. The profit of the higher price retailer is influenced by the proportionality factor and the difference between two prices. The retailer with higher price will get information rent as the proportion of lower price retailers exceeds the threshold.
