闭环供应链主体中销售商低碳行为评价

作为闭环供应链中的渠道主体,销售商实施低碳行为是企业实现资源长远利用的必然选择,是塑造企业低碳形象的必然要求,也是规避企业劣势与威胁、创造无限商机的必经之路。通过构建SEM对销售商低碳行为进行评价,运用SPSS 13.0和LISREL 8.80软件处理指标数据,筛选出关键的影响因素,并有针对性地加以改进,以期为销售商实现长期综合效益提供理论参考与技术指导。     

Joint Mail‐In Rebate Decisions in Supply Chains Under Demand Uncertainty

We study the joint decisions of offering mail‐in rebates (MIRs) in a single‐manufacturer–single‐retailer supply chain using a game theoretic framework. Either party can offer an MIR to the end consumer if it is in his best interest. The consumer demand is stochastic and depends on the product price and the amount of MIRs. When the retail price is exogenous, we show the existence of a unique Nash equilibrium under both additive and multiplicative demand functions and characterize it completely. We show that any of the following four scenarios can be the equilibrium: both parties offer MIR, only one party offers MIR, none offers MIR. When the retail price is a decision variable for the retailer and the rebate redemption rate increases with the amount of MIR, we once again prove the existence of a unique Nash equilibrium where both the retailer and the manufacturer offer MIRs. Using a numerical study, we show that the average post‐purchase price of the product is higher not only than the perceived pre‐purchase price but also than the newsvendor optimal price without an MIR. This implies that an MIR makes a product look cheaper while the consumers actually pay more on average.     

An Efficient and Robust Design for Transshipment Networks

Transshipment, the sharing of inventory among parties at the same echelon level of a supply chain, can be used to reduce costs. The effectiveness of transshipment is in part determined by the configuration of the transshipment network. We introduce chain configurations in transshipment settings, where every party is linked in one connected loop. Under simplifying assumptions we show analytically that the chain configuration is superior to configurations suggested in the literature. In addition, we demonstrate the efficiency and robustness of chain configurations for more general scenarios and provide managerial insights regarding preferred configurations for different problem parameters.     

闭环供应链再制品消费补贴政策模型分析

本文从政府提供消费补贴以鼓励消费者选择购买再制品的视角,构建了政府消费补贴下的闭环供应链博弈模型,得到了政府的最优消费补贴策略,并探讨了政府消费补贴政策对闭环供应链新品与再制品的定价、供应链总利润、消费者剩余、社会福利的影响。研究结果表明：1）只有满足特定条件时,政府才需提供再制品消费补贴;2）政府的消费补贴在制造商和消费者之间进行平均分配,因而补贴政策对制造商和消费者均有激励作用;3）政府消费补贴政策有利于供应链总利润、消费者剩余、社会福利的提高;4）政府应引导制造商专注于再制造,将废旧品的回收交由第三方回收商来完成,这有利于提高废旧产品的回收率;5）政府消费补贴政策将造成再制品对新品的市场挤兑效应。论文最后利用数值试验对研究结果进行了验证。     

Evaluating the Move to a Linear Tax System in Germany and Other European Countries

This paper proposes a comparison of the results of tax policy analysis obtained on the basis of unitary and collective representations of the household. We first generate labour supplies consistent with the collective rationality, by use of a model calibrated on microdata as described in Vermeulen et al. [Collective Models of Household Labor Supply with Nonconvex Budget Sets and Nonparticipation: A Calibration Approach (2006)]. A unitary model is then estimated on these collective data and unitary and collective responses to a tax reform are compared. We focus on the introduction of linear taxation in Germany. The exercise is replicated for other European countries and other topical reforms. Distortions due to the use of a unitary model turn out to be important in predicting labour supply adjustments, in the design of tax revenue neutral reforms, and in predicting a reform’s welfare implications.

不同管制条件下食品供应链成员企业的质量管理行为分析

质量管理体系（quality management system，QMS）的实施要求对企业的质量管理成本有着重要的影响，在自愿实施、半自愿实施与强制实施条件下企业的质量管理行为不同。通过对不同管制方式下食品供应链成员引入QMS后产品质量及成本的变动分析，认为处罚手段与力度是QMS自愿实施的一个关键条件，而监管手段与产品检测水平是强制性实施QMS的前提条件。政府的帮助对于任何一种实施方式都是必须的，但对于发展中国家而言强制实施高水平的QMS并不是一种好的选择。

垃圾短信分类治理对策研究

以垃圾短信治理问题为切入点, 以供需分析为理论基础, 从短信内容与短信发送渠道两个维度分别提出非对称二维评判矩阵和分层分级治理策略. 通过分析发现, 目前治理重点转向 "端口" 类垃圾短信, 广告类垃圾短信数量占比最大, 而诈骗、 色情等违法类短信社会危害最大, 因而提出垃圾短信分类治理的相关建议. 从新的视角研究垃圾短信治理问题, 给监管部门及电信运营企业提供理论及方法借鉴, 并促进短信业务的健康发展.
