MANAGING VENDOR INVENTORY IN A DUAL LEVEL DISTRIBUTION SYSTEM

Collaborative arrangements among members of the supply chain have received a great deal of interest in recent years as a means of reducing costs. One such arrangement is vendor managed inventory (VMI). VMI allows the vendor to make decisions concerning the quantity and timing of deliveries to the retailer. Such an arrangement offers the potential of a more efficient supply chain by removing the negative effects of retail ordering policies. A thorough review of the literature was conducted to identify factors likely to impact the performance of a VMI partnership. Computer simulation was used to study the effects of these factors from both the vendor's and retailer's perspectives. The results lend insight into the performance of VMI and guidance for managers as to the environments in which VMI is most effective.     

AN EVALUATION OF PROCESS‐ORIENTED SUPPLY CHAIN MANAGEMENT FRAMEWORKS

Supply chain management (SCM) is implemented by integrating corporate functions using business processes within and across companies. Several process‐oriented frameworks for SCM have been proposed but only two of these provide sufficient detail to enable implementation. We evaluate the Supply‐Chain Operations Reference (SCOR) framework and The Global Supply Chain Forum (GSCF) framework using four criteria and identify their relative strengths and weaknesses.     

The Contingent Value of Responsive and Proactive Market Orientations for New Product Program Performance*

While the benefits of being market oriented are largely accepted, a group of scholars and managers remain skeptical. Marketing scholars have sought to counter the criticisms leveled against market orientation (MO) by arguing that it has both responsive and proactive dimensions. However, few studies have empirically examined the complexity of the effects of these dimensions on firm performance. Drawing on theories of resource‐based advantage and organizational search behavior, this article advances understanding by arguing that responsive and proactive market orientations have curvilinear effects on product development performance, that their interaction may be positively related to product development performance, and that their effects on new product program performance are moderated differentially by the organizational implementation conditions and marketing function power. Survey results of 175 U.S. firms indicate support for most of the hypotheses. Specifically, whereas responsive MO has a U‐shaped relationship with new product program performance, proactive MO has an inverted U‐shaped relationship with new product program performance. Contrary to the arguments presented here, the interaction of both orientations is negatively related to new product program performance. This study finds that both orientations are needed; however, new product program performance is enhanced when one is at higher level and the other is at lower level. Finally, responsive MO is only positively related to new product program performance under specific conditions such as when strategic consensus among managers is high. On the other hand, the positive effect of proactive MO on new product program performance is further strengthened when learning orientation and marketing power are high. Overall, this study suggests that the effects of responsive and proactive MO on new product program performance are more complex than previously theoretically argued and empirically examined.     

围绕“内卷化”的讨论——一次新的范式转型

对于同样的一种行为——妇女参加手工业劳动,在《华北的小农经济与社会变迁》一书中不被判断为内卷化的表现,而在《长江三角洲小农家庭与乡村发展》一书中则被判断为主要的内卷化表现之一,这不能不说是“内卷化”概念的混乱。

武汉城市圈生态环境与经济发展关系研究——基于面板数据的分析

构建了环境—经济模型,并基于武汉城市圈9个城市2006年至2008的面板数据进行实证研究,结果表明:武汉城市圈经济发展与生态环境呈反向变化关系,其经济发展在某种程度上仍是以牺牲环境为代价的;同时,圈内9个城市环境与经济关系存在明显的个体差异。武汉城市圈应加大对污染产业的技术改造,推行清洁生产,并不断优化产业结构,大力发展具有高产出、低消耗、低污染的绿色产业。     

基于BDS的ADS-B报文生成系统

目前国际民航组织（ICAO）和美国航空无线电技术委员会（RTCA）有关广播式自动相关监视（ADS-B）标准中的报文数据源均规定来自全球定位系统（GPS）,而中国自主建设的“北斗”卫星导航系统（BDS）作为ADS-B数据源是必然趋势。设计了基于BDS的ADS-B报文生成系统的总体架构,利用BDS接收机接收的真实数据仿真生成了ADS-B的6种报文,并以空中位置报文的生成为例,详细阐述了报文产生涉及的关键技术以及报文的生成过程。通过运行集成后的ADS-B报文生成系统以及对所产生的6种报文的仿真验证,证明该系统总体设计思路合理,运行结果正确,可为基于BDS的ADS-B相关技术研究提供稳定可靠的ADS-B报文源。     

基于进化博弈论视角的农户群体生态移民行为分析

生态移民是当前的一个社会热点问题。文章将政府政策视为外生变量,从非理性人假设出发,构建进化博弈模型探索农户在生态移民搬迁过程中的群体行为进化规律。研究结果表明:农户存在多个进化稳定策略的可能,最终的进化稳定策略取决于搬迁农户的预期收益、因搬迁造成的实物资本损失以及非搬迁户的预期社会资本损失。因此,生态移民搬迁过程中政府部门应着重提高搬迁后农户收益水平,同时降低农户搬迁成本,以促进工程的顺利进行。     

MONEY,CAPITAL, AND EXCHANGE RATE FLUCTUATIONS*

We explore how the informational frictions underlying monetary exchange affect international exchange rate dynamics. Our perfectly flexible price model is capable of producing endogenously rigid international relative prices in response to technology and monetary shocks. The model is capable of accounting for the empirical regularities that the real and nominal exchange rates are more volatile than U.S. output, and that the two are positively and perfectly correlated. The model is also consistent with other standard real business cycle facts for the United States.
