（1）Behaviors in VMI and Performance Improvement: An Experimental Study
We conduct experiments to investigate behaviors in a supply chain where a supplier replenishes inventories for a retailer according to a VMI program under a revenue-sharing contract. The results show that decisions of subjects deviate significantly from the theoretical predictions, because the retailer presents equality preference with adjustment, and the supplier exhibits fairness concern. Since the supplier bears not only the production cost but also the risk of leftover inventory in the VMI program, we propose an approach that provides the retailer with an opportunity to voluntarily compensate the supplier an additional percentage of revenue after demand realization. Experimental results based on this new setting show that the retailer still presents the equality preference with adjustment, but the supplier has a decision bias of the ex-post inventory error regret. As a result, the supply chain with the proposed approach can perform better than the one with only the revenue-sharing contract.
（2）On Difference between Direct-response and Strategy Procedures in Decision Making: Neural Evidence in a Reward-punishment Game
In decision making, the evidence of whether direct-response procedure and strategy procedure lead to similar outcome is mixed. We conduct a neuroimaging (fMRI) experiment of a game setting with reward and punishment decisions under both procedures. The results show that, in reward decision, the direct-response procedure prompts stronger neural unwillingness and lower reward rate than the strategy procedure. In punishment decision, the strategy procedure induces stronger neural negative emotions and higher punishment rate than the direct-response procedure. Moreover, in general, subjects prefer not to choose reward when facing favorable states but tend to choose punishment when facing unfavorable states.
