浅议虚拟货币需要管制

虚拟货币随着互联网的高速发展而日显其重要性。以交流型论坛管理员、单向服务提供商为代表的相关网络经营管理者是其发行者,但并不能有效控制其发行数量。由此虚拟货币在虚拟世界中产生的问题可能对现实金融秩序发生影响,尤其体现在单向服务提供商所发行的虚拟货币上。所以目前应当着重对此类货币从发行、流通、回笼等方面进行管制。

Product resource–capability complementarity,integration mechanisms,and first product advantage

The current study extends work on resource-based theory (RBT) by exploring resource—capability complementarity in a new context—that of new technology ventures' (NTVs) first product (FP) commercialization in India. This study examines the influence of marketing and technology resource–capability complementarity on FP positional advantages (differentiation and cost-efficiency) and their influence on first product performance (FPP). Furthermore, this study incorporates the influence of supplier integration (SI) mechanisms (in terms of knowledge sharing and co-commercialization) in the process of FP commercialization. The findings suggest that asset complementarities have a positive relation with FP positional advantages, in that both differentiation and cost-efficiency enhance an NTV's FPP, and that SI moderates the relationships between both marketing and technology R–C complementarity and FP positional advantages.     

Quality management practices and their relationship to buyer’s supplier ratings: a study in the Korean automotive industry

This research explores if quality management practices are different among suppliers whose performance is rated high, medium, or low by a common buying company and identifies which specific practices contribute to the differences. The entire population of first-tier suppliers to a Korean auto assembler was surveyed to measure use of quality management practices. Useable returns were received from 25% of the suppliers surveyed. To measure conformance quality and overall rating, suppliers were categorized into high, medium, and low performing groups based on the buying company’s data. Multivariate analysis of variance was done using general linear model (GLM-MANOVA) to explore differences in the high-, medium-, and low-performing supplier groups based on their use of quality management practices. No statistically significant differences were found when suppliers were categorized based on conformance quality. However, when categorized based on overall rating, the highest rated suppliers were found to emphasize process management and employee satisfaction to a greater degree than the lowest rated suppliers.     

Optimal requirement allocation among quantity-discount quoting suppliers

We consider a problem motivated by a central purchasing organization for a major office products distributor. This purchasing organization must source a quantity of a particular resale item from a set of capacitated suppliers. In our case each supplier offers an incremental quantity discount purchase price structure. The purchaser’s objective is to obtain a quantity of a required item at minimum cost. The resulting problem is one of allocating order quantities among an approved supply base and involves minimizing the sum of separable piecewise linear concave cost functions. We develop a branch and bound algorithm that arrives at an optimal solution by generating linear knapsack subproblems with feasible solutions to the original problem. This research was partially supported by a 2007 Summer Research Grant awarded to Asoo J. Vakharia.

The impact of supplier development on buyer competitive advantage: A path analytic model

As manufacturing firms increasingly realize that supplier performance is crucial to their establishing and maintaining competitive advantage, supplier development has been a subject of considerable research in supply chain management. We develop and test a path model to explore how supplier development practices affect buyer-supplier performance from the buying firm's perspective in the context of Hong Kong's electronics industry. The results show that top management, supplier evaluation, and supplier strategic objectives are significant determinants of transaction-specific supplier development, and that buyers that have closer collaborative relationships with suppliers may strengthen their competitive advantage.     

Becoming a preferred customer one step at a time

A preferred customer is a buying organization who receives better treatment than other customers from a supplier, in terms of product quality and availability, support in the sourcing process, delivery or/and prices. The decision to become a preferred customer implies a continuous commitment by the purchaser to a complex, expensive and often uncertain process. It is important to use a strategic approach, as well as appropriate tactics. Based on well-known models on the development of buyer-supplier relationship, on customer portfolio analysis and on the emergent literature in customer attractiveness and preferred customer status, we suggest four steps to become – and remain – a preferred customer: initial attraction, performance, engagement and sustainability. The process takes the perspective of a buyer willing to obtain the preferential status and focuses on the strategies and tactics that could influence the supplier's decision of granting this status. The proposed process considers that the supplier is continuously comparing the value offered by the customer to its expectations, and to the value offered by other customer relationships.     

Towards a taxonomy-based preferred-customer model for suppliers in air cargo express service markets

Drawing on social exchange and push–pull–mooring theories, this paper develops a taxonomy-based preferred-customer model for B2B air express markets. Our model extends the conventional bilateral customer-supplier relationship perspective of customer portfolio management to include competition effects for more comprehensive (trilateral) strategic decision making. Based on this unified framework, our a survey of 180 customers of air cargo express carriers identifies three distinctive groups of preferred customers. In addition to the effect of competitors on air express carriers’ prioritization of customers, which is further complicated by a satisfaction paradox and spurious loyalty, we further establish classification indicators for differentiating preferred from non-preferred customers. Notably, although commonly used in practice, we find sales volumes to be ineffective for that purpose.
