Extant research has examined the effects of amount‐off discounts on consumer responses, but the empirical findings are inconsistent. This study presents a meta‐analysis of 19 studies and 86 effect sizes (N = 12,003) calibrating the effects of discount frames on consumer responses. Amount‐off discounts are found to lead to positive consumer responses through positive changes in attitudes. Analyzing various moderators’ impacts shows that amount‐off discounts have different effects depending on the product price level, the product type, and the price promotion mode. For instance, amount‐off discounts tend to be more effective than percentage‐off discounts when the price is high, when the product type is material, and when the price promotion mode is a discount.

Call admission control (CAC) is one of the most important parts of resource management in mobile communication systems. It keeps the system work stable by accepting or rejecting users' service requests. CAC solves the conflict between the service satisfaction of user and system resource utilization. This paper focuses on the dynamic CAC strategy providing guaranteed fairness in the CDMA systems with non-uniform traffic distribution among cells. A novel CAC strategy, which can support multi-traffic with different QoS requirements and VBR traffic, is proposed based on former research achievements. By adopting greedy algorithm, whether accepting or rejecting a new call request depends on the target Signal-to-Interference of the whole system. Therefore the equilibrium of blocking probability among cells with different arriving rates and the access fairness is guaranteed. It is very significant for practical system applications.
