Supply Chain Decision-Making Considering Green Technology Effort: Effect on Random Output and Retail Price with Fairness Concerns

In the context where the random output and retail prices of green products depend on green technology effort, this study considers three cases: only the supplier or retailer has fairness concerns, and both are risk neutral.A twolevel supply chain complete information dynamic game model, comprising the follower supplier and dominant retailer, is constructed to study the respective supply chain decision-making problem.The results show that: (1) the supplier's expected profit is the highest when they have fairness concerns, followed by the cases wherein both are risk neutral and the retailer has fairness concerns, respectively; (2) the retailer's expected profit (retail price) is the highest in a riskneutral situation, followed by the cases wherein the retailer (supplier) and the supplier (retailer) have fairness concerns, respectively; (3) the magnitudes of order quantity, wholesale price, and green technology effort in the three situations are complicated and depend on each parameter's size.
