The Effects of Supplier Involvement and Knowledge Protection on Product Innovation in Customer–Supplier Relationships: A Study of Global Automotive Suppliers in China

Globalization drives firms to develop product innovation through their global supply chains. While innovations generated by supply channel members, as opposed to individual partners, are playing an increasingly important role in the success of all supply chain partners, there has been limited research on how supply chain relationships cultivate the process of such innovation generation, particularly in emerging markets. Correspondingly, this study explores how multinational suppliers can develop adaptive product innovation to create competitive advantage in emerging markets. Drawing on the knowledge‐based view and transaction cost economics, this study investigates the influence of supplier involvement and other factors on supplier innovation and performance. The results of a survey of 170 multinational automobile suppliers in China provide support for most of the hypotheses. Specifically, supplier involvement in codesign has an inverted U‐shaped relationship with product innovation. Furthermore, knowledge protection, trust, and technological uncertainty are all found to drive greater product innovation. In addition, the institutional environment moderates the effect of product innovation on performance. Overall, this study enhances our understanding of how MNEs can acquire local knowledge and develop adaptive products in emerging markets.     

Measuring a contract's breadth: A text analysis

We use a computational linguistic algorithm to measure the topics covered in teacher contracts. Topic modeling metrics are used to assess a contract's expansiveness. Our topic, diversity measurement, is then related to the prevalence of support staff. If more specialized services are provided, then contracts should be broader as they cover more employment relationships. We confirm a strong, statistically significant relationship and, thus, have a valid measurement of contract breadth.     

Lead independent directors and accruals quality

We investigate the association between firms having a lead independent director (LID) who serves on the audit committee and accruals quality using a sample of 32,346 observations during 2001–2018 period. Our results suggest that firms with an LID who serves on the audit committee are associated with higher accruals quality. The results suggest that these firms are associated with an increase in accruals quality equal to 6.60% of the accruals quality metric's median value. We also find that as board size increases, the positive influence of an LID on accruals quality weakens—but only for firms with an LID who does not serve on the audit committee. Supplemental analyses indicate that our inferences still hold when using a changes model, when examining a firm's initial adoption or elimination of the LID position, and when using an entropy balancing approach.
