Item SUPPLY CHAIN RISKS, RESILIENCE AND FIRM PERFORMANCE: AN EMPIRICAL STUDY(2018) Martinez, Camil; Dresner, Martin; Business and Management: Logistics, Business & Public Policy; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)This dissertation’s main focus is the study of supply chain resilience. The two studies investigate the impact of supply chain geographical locations risks and supply chain resilience on performance and of supply chain risks and disruptive events in resilience strategies. Essay 1 seeks to understand the impact of supply chain resilience strategies on firm’s performance. We utilize a cross sectional data sample from 2014 containing detailed manufacturing location risk data and resilience planning at the location level for 313 publicly traded firms. We look at three supply chain resilience cultural traits, business continuity planning, inventory and financial stability. We find that resilience has a positive effect on firm performance. Essay 2 looks at the impact of two types of supply chain risks (internal and external) and two types of disruptive events (internal and external) in the development of supply chain resilience strategies. We find that external disruptive events have a positive impact on supply chain resilience but internal disruptive events have a negative impact in the development of resilience. However, once a business continuity plan is in place, previous internal disruptive events are associated with more agility. My findings for both essays contribute to the supply chain resilience literature by empirically testing the impact of resilience on performance and the impact of disruptive events on resilience strategies.Item Interorganizational Innovation: The Role of Suppliers in Enhancing Buyer Innovation(2016) Elking, Isaac; Grimm, Curtis M; Business and Management: Logistics, Business & Public Policy; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)This dissertation explores the effect of innovative knowledge transfer across supply chain partners. My research seeks to understand the manner by which a firm is able to benefit from the innovative capabilities of its supply chain partners and utilize the external knowledge they hold to increase its own levels of innovation. Specifically, I make use of patent data as a proxy for firm-level innovation and develop both independent and dependent variables from the data contained within the patent filings. I further examine the means by which key dyadic and portfolio supply chain relationship characteristics moderate the relationship between supplier innovation and buyer innovation. I investigate factors such as the degree of transactional reciprocity between the buyer and supplier, the similarity of the firms’ knowledge bases, and specific chain characteristics (e.g., geographic propinquity) to provide greater understanding of the means by which the transfer of innovative knowledge across firms in a supply chain can be enhanced or inhibited. This dissertation spans three essays to provide insights into the role that supply chain relationships play in affecting a focal firm’s level of innovation. While innovation has been at the core of a wide body of research, very little empirical work exists that considers the role of vertical buyer-supplier relationships on a firm’s ability to develop new and novel innovations. I begin by considering the fundamental unit of analysis within a supply chain, the buyer-supplier dyad. After developing initial insights based on the interactions between singular buyers and suppliers, essay two extends the analysis to consider the full spectrum of a buyer’s supply base by aggregating the individual buyer-supplier dyad level data into firm-supply network level data. Through this broader level of analysis, I am able to examine how the relational characteristics between a buyer firm and its supply base affect its ability to leverage the full portfolio of its suppliers’ innovative knowledge. Finally, in essay three I further extend the analysis to explore the means by which a buyer firm can use its suppliers to enhance its ability to access distant knowledge held by other organizations that the buyer is only connected to indirectly through its suppliers.
