How does a component from a supplier with high reputation for product innovation improve the perception of a final offering? A process perspective

An excellent reputation for product innovation (RPI) is an intangible asset for any company and promises a sustainable competitive advantage. This study empirically analyzes the spillover effects of a high component supplier's RPI to the offering of the original equipment manufacturer (OEM). The results show that there are positive effects to be gained from the innovativeness of a component supplier, which increases the perceived performance of the final offering containing the supplier's product. In addition, the study demonstrates that such a strategic partnership between a component supplier and an OEM has the potential to influence the purchase intention of the final consumer in a positive manner, thereby creating value for both parties. Contributions are made to a better understanding of strategic options for such a partnership and to an on-going discussion on RPI and the importance of intangible attributes in innovation management.     

Quick response and supply chain structure with strategic consumers

This work explores the impact of quick response on supply chain performance for various supply chain structures with strategic customer behavior. By investigating pricing and inventory decisions in decentralized supply chains under revenue-sharing contracts and in centralized supply chains, we study the performance of four various systems and compare the value of quick response in different supply chain structures. The results show that if the extra cost of quick response is relatively low, the value of quick response would be greater in centralized systems than in decentralized systems. On the other hand, if the extra cost is high, decentralized supply chains reap more incremental profits from adopting quick response. We also find that revenue-sharing contracts enable a decentralized supply chain to outperform a centralized supply chain, but only allow limited flexibility of allocating total profits between a manufacturer and a retailer.     

Coordinating a supply chain for deteriorating items with a revenue sharing and cooperative investment contract

In this study, a one-manufacturer–one-retailer supply chain model for deteriorating items with controllable deterioration rate and price-dependent demand is developed, in which both players cooperatively invest in preservation technology to reduce deterioration. Algorithms are designed to obtain the pricing and preservation technology investment strategies in both integrated and decentralized scenarios. It is shown that cooperative investment strategy benefits the manufacturer but damages the profits of the retailer and the whole supply chain. A revenue sharing and cooperative investment contract, which combines revenue sharing and cost sharing mechanisms, is thus designed to coordinate the supply chain. Numerical simulations and sensitivity analysis of the equilibrium strategies and coordinating results on key system parameters are given to verify the effectiveness of the contract, and meanwhile get some managerial insights. The results show that only when the revenue sharing rate lies roughly between 1/2 and 3/4 can the contract perfectly coordinate the supply chain in most cases, which has an important guiding significance for the supply chain coordination of deteriorating items when considering preservation technology investment.     

Impact of secondary market on consumer return policies and supply chain coordination

In this paper, we develop a unified model to study the inventory management problem of a product and the coordination of the associated supply chain consisting of a single supplier and considerably many retailers in the presence of a secondary market. Specifically, consumer returns are allowed in the initial sales. Then, we introduce a secondary market to salvage the returns and the leftovers from the initial sales. In this secondary market, a discount price will be offered to the consumers but no returns are accepted. Moreover, between the primary and the secondary market, there is an internal market where retailers can trade among themselves so that they are able to adjust their inventory levels to prepare for the sales in the secondary market. We study the retailers' and the supply chain's inventory decision in this case and highlight the impact of the secondary market on the sales as well as on the supply chain coordination contracts. We conclude that the secondary market helps us to increase the total wholesale volume. Numerical examples show that the total sales profit is also increased. However, the secondary market aggravates the incentive conflict between the retailers and the supply chain on deciding the optimal inventory levels and hence requires the supplier to offer more generous buyback or sales rebate contracts for coordination of the supply chain. Finally, we extend our analysis to more general cases and also show that our results are robust to some of the modeling assumptions.     

Consignment or wholesale: Retailer and supplier preferences and incentives for compromise

We consider two independently managed parties, a retailer and a supplier, that are considering either a wholesale or a consignment contract to produce and market a single good. Both parties have an interest in reaching an agreement, but their first choice of contract type are generally not the same. We define the strength of retailer and supplier preferences for their respective choices of contract type as the ratio of their expected profits for their first choice of contract type over that for the alternative contract type. We study how uncontrollable factors as well as controllable factors affect the strength of retailer and supplier contract preferences. We develop incentive payments that can potentially be used to increase the likelihood of success in negotiating an agreement.     

The Importance of Social Embeddedness: Churn Models at Mobile Providers

This article argues the importance of social embeddedness at mobile providers by examining the effects of customers’ network topological properties on churn probability—the probability of a customer switching from one telecommunication provider to another. This article uses data from regional snowball sampling—the only practically feasible network sampling method—to identify groups with significantly different churn ratios for customers with different network topological properties. Clear evidence indicates that individual network characteristics (node‐level metrics) have considerable impact on churn probabilities. The inclusion of network‐related measures in the churn model allows a longer‐term projection of churners and improves the predictive power of the model. With no possibility to carry out repeated sampling, sample stability was checked through simulation results. On the one hand, this article highlights the importance and effectiveness of the provider's tailored marketing campaigns by showing that customers targeted by direct marketing campaigns are less threatened by churn than nontargeted customers. On the other, this article shows that social embeddedness blocks the impact of the very same marketing efforts. This article forwards the idea that social embeddedness, also prevalent in vendor switching, can be extended to understanding the development of professional societies threatened by membership churn.     

论社会保障制度改革

加入WTO的外部压力和经济转型的内部压力带来日益严重的失业问题和弱势群体,使得我国社会风险日趋严重。但目前存在结构性偏差的社会保障制度还难以应付上述风险。为此,当前社会保障制度改革决策的基点在于结构性调整,即在社会保障的制度安排上应迅速强化社会救济制度。同时,在社会保障的制度变迁中应将国企产权关系的调整与社会保险制度的调整结合起来,适时地将国有资产的变现收入划入社保基金。另外,在社会保险的制度供给上应大力推行强制性的补充养老保险制度。

Leveraging Supply Chain Integration through Planning Comprehensiveness: An Organizational Information Processing Theory Perspective

This study extends prior research on supply chain planning and integration by examining the underlying capabilities by which firms exploit the information they gain from integration activities. We use organizational information processing theory (OIPT) to develop hypotheses that identify the comprehensiveness of an organization's supply chain planning capabilities as an important mediator in the relationship between its supply chain integration activities and its operational performance. Further, our interpretation of OIPT suggests that an organization's usage of technology‐enabled supply chain management systems (SCMS) moderates these effects. Using survey data from 445 global firms, we estimate the corresponding moderated‐mediation structural model. The results indicate that usage of SCMS enables organizations to better utilize the information they gain from external integration efforts (relationships with customers and suppliers), thus improving the comprehensiveness of their supply chain planning capabilities. In contrast, the use of SCMS appears to be a partial substitute for internal integration as a driver of planning comprehensiveness. Most importantly, the results suggest that planning comprehensiveness is a significant generative means by which integration and technology investments produce superior operational performance. These findings provide a richer and more theoretically grounded explanation of relationships between supply chain integration, supply chain planning, and operational performance.
