Product variety,sourcing complexity,and the bottleneck of coordination

Research summary: This paper studies the coordination burden for firms that pursue variety as their main product strategy. We propose that product variety magnifies the tension between scale economies in production and scope economies in distribution, giving rise to complex sourcing relationships. Sourcing complexity worsens performance and poses a dilemma for organization design: A hierarchical structure with intermediate coordinating units such as sourcing hubs reduces sourcing complexity for downstream distribution but creates bottlenecks at the hubs, hurting performance for both the hubs and downstream distribution. We empirically examine operations data for about 300 distribution centers within a major soft drink bottling company in 2010–2011. Results support our hypotheses, illuminating the source of complexity in multi‐product firms and the challenge for organization design in managing complexity. Managerial summary: This paper uses data for about 300 distribution centers within a major soft drink bottling company to study how a large product variety creates complex sourcing networks. We find that, in addition to poor performance (e.g., increased stockouts), complex sourcing networks can cause challenges for organization design. In particular, the benefits of converting an existing distribution center into a sourcing hub (i.e., reduction in sourcing complexity for downstream distribution) and the costs of doing so (i.e., reduction in performance for both the hubs and downstream distribution) are both real and significant. The design of an efficient sourcing network despite its complexity involves important managerial decisions. Experiences in building and managing such networks can be the basis of a dynamic capability. © 2016 The Authors. Strategic Management Journal published by John Wiley & Sons Ltd.     

At‐home meat consumption in China: an empirical study*

The remarkable economic changes occurring within China since 1978 have resulted in a striking alteration in food consumption patterns, and one marked change is the increasing consumption of meat. Given China’s large population, a small percentage change in per capita meat consumption could lead to a dramatic impact on the production and trade of agricultural products. Such changes have major implications for policy makers and food marketers. This paper concentrates on meat consumption patterns in the home in China. A censored linear approximate almost ideal demand system model was employed in the study, and major economic parameters were estimated for different meat items. Data used in this study were collected from two separate consumer surveys – one urban and one rural in 2005.

能源相对价格、技术进步与出口规模增长

现存文献已经证明中国的能源消费对中国出口贸易有重要的影响,但是对能源价格对出口影响研究的并不多,本文从理论和实证角度分析了中国的能源价格和出口量之间为什么同方向变化。分析表明,中国的能源价格是通过技术进步和国内外能源价格差来影响中国出口量变化的,实证结果也证实了理论分析的结论。实证结果表明,技术进步对出口量的长期影响为正,而国内外能源的相对价格对出口量的影响为负。     

扶持林业的经济均衡观

林业的市场失灵源于其公共物品属性、效益外部性和弱质性,而市场失灵的后果使林业在市场中无法实现微观良性循环,即林业经济的不均衡。应用逻辑推理和直观定量的视角,重点剖析林业投入环节微观循环的前提性、基础性的先天缺陷,产出环节微观循环的微观补偿不畅性、萎缩性,并按照社会平均收益的回报或投资林业的机会成本与投资林业实际平均回报之间的差额,以及帕累托均衡原理,初步确定了能够维持林业经济均衡的对微观林业实行经济扶持的量的尺度与标准,进而提出实现林业经济均衡必须依靠国民收入的再分配和政府扶持的论断。
