The phenomenon of global warming and climate change has increasingly attracted attention by researchers in the field of supply chain and operations management. Firms have developed efficient plans and intervention measures to reduce greenhouse gas (GHG) emissions. While a majority of research in supply chain management has adopted a firm-centric view to study environmental management, this dissertation focuses on the context of GHG emissions reduction by considering a firm’s vertical and horizontal relationships with other parties, and the associated spillover effects. A theoretical framework is first proposed to facilitate the field's understanding of the possible spillover effects in GHG emissions reduction via vertical and horizontal interactions. Two empirical studies are then presented to test the spillover effect in GHG emissions reduction, focusing on the vertical interactions - when firms interact with their supply chain members. Drawing data from Bloomberg Environmental Social and Governance, and Bloomberg SPLC, this study conducts econometric analyses using various models. The results suggest that first, a higher level of supply chain GHG emissions is associated with the adoption of emissions reduction programs by a firm, and that this supply chain leakage contributes to the firm’s financial performance. Second, a firm's supply base innovativeness can contribute to its internal GHG emissions reduction, and this effect is contingent on a firm's supply base structure. As such, this dissertation answers the recent call in the field of supply chain and operations management for more empirical research in socially and environmentally responsible value chains. Further, this study contributes to the literature by providing a better understanding of the externalities that value chain members can impose on one another when pursuing sustainability goals.

In this dissertation research, I expand the definition of the supply network to include the buying firm’s competitors. Just as one buyer-supplier relationship impacts all other relationships within the network, the presence of competitor-supplier relationships must also impact the focal buying firm. Therefore, the concept of a “competitive network” made up of a focal firm, its competitors and all of their combined suppliers is introduced. Utilizing a unique longitudinal dataset, this research explores how the organic structural changes within the new, many-to-many supply network impact firm performance. The investigation begins by studying the change in number of suppliers used by global auto manufacturers between 2004 and 2013. Following the Great Recession of 2008-09, firms have been growing the number of suppliers at more than twice the rate they had been reducing suppliers just a few years prior. The second phase of research explores the structural changes to the network resulting from this explosive growth in the number of suppliers. The final investigation explores a different flow – financial flow -- and evaluates its association with firm performance. Overall, this dissertation research demonstrates the value of aggregating individual supply networks into a macro-network defined as the competitive network. From this view, no one firm is able to control the structure of the network and the change in structure directly impacts firm performance. A new metric is introduced which addresses the subtle changes in buyer-supplier relationships and relates significantly to firm performance. The analyses expand the body of knowledge through the use of longitudinal datasets and uncovers otherwise overlooked dynamics existing within supply networks over the past decade.

Firms are increasingly being held accountable for the unsustainable actions of their suppliers. Stakeholders, regulatory agencies, and customers alike are calling for increased levels of transparency and higher standards of corporate social responsibility (CSR) performance for suppliers. While it is apparent that supplier performance is important, it remains unclear how the stock market weighs the CSR performance of a supplier relative to that of a focal firm. This dissertation focuses on whether these relative differences exist. In addition to capturing the magnitude of the difference in market impact between focal firm and supplier CSR events; I analyze the ways in which these differences have changed over time. To capture this evolution, CSR events ranging over a period from 1994 to 2013 are examined. This research utilizes an event study methodology in which the announcement of over 2,300 CSR events are identified and analyzed to determine the subsequent stock market reaction. I find that while the market evaluated negative supplier CSR events less harshly than events occurring at the buying firm in the early years of the sample, by the turn of the millennium this “supplier discounting" had disappeared. The analysis is broken down by CSR event "type". Findings demonstrate that negative CSR events, particularly those revolving around worker or customer safety, generate the most significant abnormal return. The findings of this dissertation produce valuable managerial insights along with interpretation. Resources are scarce, and understanding where a firm might best allocate their resources to avoid financial penalties will be valuable information for corporate decision makers. These findings present clear evidence that some of these resources should be allocated to supplier CSR performance, not just towards the CSR performance of the focal firm.

While agency problems inevitably exist in buyer-supplier relationships, the focus on how to overcome such problems has been confined to the buyer-supplier dyad as if the dyad exists in isolation. In this dissertation, I re-frame the agency problems beyond the dyadic relationship between a buyer and its supplier and suggest a new way to overcome agency problems. While the current Agency Theory suggests that the buyer can monitor and provide incentives to mitigate the agency problems, I propose to look beyond the dyad in addressing buyer-supplier agency problems.

In the first chapter, I examine the impact of the “indirect links” in which the buyer is connected to the supplier through a third actor. I propose a conceptual framework that specifies how the indirect links can overcome agency problems through the effects of information exchange, mutual monitoring, power change, and network governance. These different effects are enabled by the indirect links based on the different network positions and levels of connectivity of the third actor. The first chapter provides a theoretical framework for Chapter 2 and 3.

In Chapter 2, the effect of network governance enabled by the indirect links is investigated. In particular, two scenario-based role-play experiments were conducted with managers to examine the effects of dyadic and network governance mechanisms on supplier opportunism. In Study 1, the participants took the perspective of a supplier, while in Study 2, the participants took the role of a buyer. The results show that network governance mechanism reduces the supplier's opportunistic behavioral intentions directly and indirectly through the negative affection prediction, and while suppliers may overlook the buyer's reactions as they make decisions, the buyers are likely to react against the supplier, such as engage in negative word-of-mouth or reduce level of commitment.

Finally, directed sourcing, a direct application of how a buyer could overcome agency problems beyond the dyad, is examined in Chapter 3. Directed sourcing is an emerging sourcing practice in which the buying firms bypass the top-tier suppliers and directly manage or contract with lower-tier suppliers, and research on this new practice is in its infancy. Therefore, multi-tier multi-task principal-agent models are developed to investigate the effect of directed sourcing practice on each member in this three-tier supply chain, comparing with traditional tiered sourcing. The results show that directed sourcing generally benefits the original equipment manufacturer (OEM) and the lower-tier supplier, while it harms the top-tier supplier. Yet, directed sourcing is not always beneficial to the OEM. Therefore, an OEM should be selective in implementing this new strategy.

In the current knowledge economy, the decision on whether to outsource knowledge assets is arguably the most important decision in operations and supply chain management (OSCM). However, the theories of transaction cost economics (TCE) and the resource-based theory (RBT) are inconsistent in their ability to predict, describe or explain knowledge outsourcing decisions. Currently, a theory to explain this important OSCM decision does not seem to be available. This dissertation takes a view that strategic decisions like that of knowledge asset outsourcing are made by a two step decision process where (1) an individual level cognitive process where managers generate their solutions and (2) a firm level social process where managers seek to influence other managers about their opinion. Part I uses a behavioral experiment to understand how managers form their solutions to the knowledge outsourcing question. The part tests if the psychological closeness to a task being outsourced i.e. the task affinity and self-interest influences the managers to subvert the rational decision process and make “favorable” outsourcing decisions. Additionally, it also tests if the influence is indirect and mediated by the perception of asset specificity (TCE variable) and core competence (RBT variable). Part 2 adopts a naturalistic paradigm and conducts case study research to understand how these cognitive managers with different mindsets try to influence the firm decision. The structuration theory framework is adopted to study 11 decision opportunities and frame a typology of decision processes that are used by managers. The parsimonious typology has 4 ideal types based on the nature of data exchange (naive and involved) and the nature of mindset exchange (naive or involved). The dissertation offers a comprehensive understanding of how knowledge asset outsourcing decisions emerge. It aligns the strategy research in OSCM field to the current beliefs in strategic management. The typology can be used to develop contingencies that suggest the type of decision process to use in different conditions. The experiment validates that TCE and RBT influences how managers make decisions but shows that task affinity and self-interest influences the perception of core competency and the outsourcing decision.
