The effects of suppliers’ trust on manufacturers’ innovation capability: an analysis of direct versus indirect relationships

The study offers an alternative explanation for the role of trust in economic exchange, answering the critical research questions of how and under what conditions suppliers’ trust affects manufacturers’ innovation capability. The study adopts a transaction value approach suggesting combining strategy and organisational economic literature to fully investigate the processes through which joint value is generated and developed by interacting partners. Using survey data from a sample of 235 supplier–manufacturer relationships, we find broad support for the model hypotheses. The results confirm the mediating role of asset specificity and knowledge sharing as procedural dimensions in the relation between suppliers’ trust and manufacturers’ innovation capability. However, the direct path between trust and innovation capability was not confirmed. The study provides theoretical and practical implications for firms seeking to translate inter-firm trust into innovation-based competitive advantage.

Supplier quality assessment to identify depth technical knowledge of component reliability

As a result of global competition, international companies that manufacture photocopiers, printers or car navigation systems have to purchase low-cost electronic components such as semiconductors and hard disk drives by outsourcing production. However, it is often difficult for these companies to evaluate the quality of their suppliers through interviews and technical documentations. This article proposes new measures for supplier assessment and a systematic approach to select suppliers that have in-depth knowledge of component reliability and technology. The measures for selection not only include the physical quality of components but also information disclosures provided by suppliers, which consist of failure analysis, reliability data and details of the design-manufacturing process. The proposed measures are applied to real data of photocopier manufacturing enterprises. Experiments conducted show that a systematic assessment will enable selecting appropriate suppliers with a lower failure rate.     

A Multi‐Supplier Sourcing Problem with a Preference Ordering of Suppliers

We study a sourcing problem faced by a firm that seeks to procure a product or a component from a pool of alternative suppliers. The firm has a preference ordering of the suppliers based on factors such as their past performance, quality, service, geographical location, and financial strength, which are commonly included in a supplier scorecard system. Thus, the firm first uses available inventory from supplier 1, if any, then supplier 2, if any, and so on. The suppliers differ in costs and prices. The buyer firm seeks to determine which suppliers to purchase from and in what quantities to maximize its total expected profit subject to the preference ordering constraint. We present the optimal solution to this problem, and show that it has a portfolio structure. It consists of a sub‐set of suppliers that are ordered by their underage and overage costs. This portfolio achieves a substantial profit gain compared to sourcing from a unique supplier. We present an efficient algorithm to compute the optimal solution. Our model applies to component sourcing problems in manufacturing, merchandizing problems in retailing, and capacity reservation problems in services.     

论产品质量纠纷中供货者的责任

供货者处在产品流通过程的中间环节，不同于流通链条两端的生产者与销售者，在产品质量纠纷中具有特殊法律地位，为避免过多“内部求偿”之诉讼浪费，不必与生产者或销售者就产品缺陷损害承担连带责任，而应采取相对法定责任的模式。现行产品质量法关于供货者与销售者的规定含混不清，不利于消费者群体及各方合法权益的平衡，必须对供货者的责任分担作出具体明晰的规定。     

On the Same Page? How Asymmetric Buyer–Supplier Relationships Affect Opportunism and Performance

Research on buyer–supplier relationships (BSRs) has often focused on only one side of the relationship and, thus, has tended to overlook asymmetries. Yet, a buyer (supplier) may often deal with a bigger supplier (buyer) or one that has higher levels of trust, respect, and reciprocity. Therefore, we examined how two types of asymmetries—size and relational capital—affect perceived opportunism and performance. We used dyadic data from 106 buyers and their matched suppliers gathered from a survey and an archival database. The results demonstrate that the degree and direction of both asymmetries affect the BSR. Our results also reveal that an imbalance of relational capital in a firm's favor may have the opposite effect from that intended. In other words, the firm's counterpart perceives more, rather than less, firm opportunism. The results also suggest that a buyer observes lower benefits in the presence of size asymmetry, whereas the supplier's perception of benefits is unaffected. Thus, our research represents a significant step forward in understanding BSRs and asymmetries by (i) bringing attention to two key asymmetries inherent in BSRs and (ii) showing that these asymmetries are not unidirectional in their influence on perceived opportunism and performance.

Supplier Behavior in Capacity Investment Competition: An Experimental Study

Many manufacturers ensure supply capacity by using more than one supplier and sharing their capacity investment costs via supplier development programs. Their suppliers face competitive pressure from peers despite the reduced capacity investment cost. Although standard game theory makes clear prediction that cost sharing increases the suppliers' capacity choice and supply chain profit, the complex decision environment of capacity competition makes it interesting to test whether the theory predictions are robust and, if not, whether systematic deviations occur. We present a laboratory experiment study. The experiment data show that supplier subjects invested in higher capacities than what our theoretical analysis predicted, resulting in profit loss for the supply chain. Our econometric analysis indicates that the subjects are bounded rational and their concern for relative standing may be the potential driver of capacity over‐investment. Based on the experimental findings, we study a modified cost‐sharing mechanism that adapts to the behavioral biases. Its performance is validated in a second experiment.     

Strategic Inventory and Supply Chain Behavior

Based on a serial supply chain model with two periods and price‐sensitive demand, we present the first experimental test of the effect of strategic inventories on supply chain performance. In theory, if holding costs are sufficiently low, the buyer builds up a strategic inventory (even if no operational reasons for stock‐holding exist) to limit the supplier's market power, and to increase the own profit share. As it turns out, this enhances the overall supply chain performance. The supplier anticipates the effect of the strategic inventory and differentiates prices to capture a part of the increased supply chain profits. Our results show that the positive effects of strategic inventories are even more pronounced than theoretically predicted, because strategic inventories empower buyers by shifting the perception of the fair split. Overall, strategic inventories have a double positive effect, a strategic and a behavioral, both reducing the average wholesale prices and dampening the double marginalization effect. The latter effect leads to more equitable payoffs.
