    Buy Now, Think Later: Product Returns and Firm Performance
    (2018) Pritchard, Alan Matthew; Windle, Robert J.; Evers, Philip T.; Business and Management: Logistics, Business & Public Policy; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)
    This dissertation studies the short-term and long-term impacts of return policies and feedback text on firm performance. Archival data, text analytics, and econometric analysis are used to further develop signaling theory, transaction cost economics, and procedural justice theory in operations, logistics, and supply chain management. The first essay is motivated by the ambiguity of prior research on the relationship between return policies and demand in the online setting. The return policy components that impact landed prices are identified and the relationships between terms of sale and demand are studied. After controlling for price, a lenient return policy is found to signal the unobservable quality of the seller’s product and demonstrate their capability to properly handle sales, shipping, and returns. A lenient return policy also helps mitigate customers’ risk associated with a mismatch between the product and their expectations and is shown to be positively associated with landed price and demand. The second essay demonstrates that the impact of a customer’s satisfaction or dissatisfaction with a seller or their product extends to other customers when their satisfaction or dissatisfaction becomes public knowledge, impacting sellers’ future demand. The impact of negative, trust revoking feedback is shown to differ from the impact of non-trust revoking, negative feedback, such as nonspecific complaints and complaints about price. In other words, the text associated with numerical feedback ratings determines the strength of the negative rating’s impact. Moreover, it is shown that negative feedback can be altered and even counteracted with a satisfactory service recovery, while the variance of complaint types in sellers’ feedback histories is negatively associated with demand. Overall, this dissertation demonstrates the benefits of two signals of quality: a lenient return policy and positive feedback history. Methodological contributions include the use of two original datasets and the combination of text analytics and regression analysis to inform managerial decisions. Managerial implications suggest that firms should take the leniency of their return policies and the strength of their online reputations into consideration when pricing and estimating demand.

    The Impact of Executives with Supply Chain Management and Operations Management Experience on Recall Performance and Risk Management
    (2017) Paraskevas, John-Patrick; Grimm, Curtis; Corsi, Thomas; Business and Management: Logistics, Business & Public Policy; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)
    This dissertation investigates the impact of the growing presence of executives with supply chain management and operations management (SCOM) experience on the top management team. My dissertation focuses on two major strategic areas in which an executive with SCOM experience may influence firm strategy and firm performance. The first area I have chosen to study is a firm's propensity to engage in product recalls along with their responsiveness to the quality glitches that lead to recall. The second area of study is risk and resilience within a firm’s supply chain. Essay 1 explores the impact of an executive with SCOM experience on product recall propensity and firm responsiveness. We utilize a unique dataset collected from multiple sources on executives’ backgrounds and product recalls, and we find that firms having top management executives with SCOM backgrounds have fewer recalls and faster recall responsiveness. The findings also indicate that the shortened speed to recall is enhanced when a firm engages in a proactive recall strategy. The second essay studies the impact of top executives with SCOM experience as well as top executives with finance experience. We then propose original hypotheses regarding the impact of these two forms of experience on the firm’s supply chain risk profile. We utilize a dataset of manufacturing locations over a three-year period. Our findings indicate that firms with SCOM experience on their top management teams have lower levels of location risk and higher levels of resilience at their production locations. On the other hand our findings indicate that firms with top management teams with finance experience are more likely to take on location risk at their production locations but are similar to firms with SCOM on their top management team in that they also have high levels of resilience. Lastly we explore the impact of an SCOM executive when the firm uses offshore production. My findings for both essays contribute to upper echelons theory (UET) by proposing and testing novel hypotheses regarding the impact of the presence of executives with SCOM experience and finance experience on recall performance and supply chain risk management.

    Two Esays on Trust in Supply Chain Management
    (2011) Ozpolat, Koray; Dresner, Martin E.; Business and Management: Logistics, Business & Public Policy; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)
    In this dissertation, I propose that trust is an important yet under-studied concept in supply chain relationships both upstream in a Business-To-Business (B2B) context and downstream in a Business-To-Consumer (B2C) context. In the first essay, I investigate the evolution of trust in buyer-supplier relationships in a VMI setting. Supply chain management literature is rich in pointing to the benefits generated by collaborative supply chain arrangements, however recently the dark side of these collaborative relationships has been reported as well. To the best of our knowledge, our study is the first to bring in a new dimension - "length of the relationship" to these research models. Using survey data collected from distributors that use VMI, we find that longer relationships are associated with lower levels of distributor trust in the manufacturer. This erosion of trust over time is fully mediated by the distributors' experience of psychological contract violation. Our findings demonstrate that good inventory performance may not be sufficient to maintain trust in VMI relationships, but regular communication between parties, as well as nonverbal documented agreements, may also be needed to maintain trust. In the second part of the dissertation, I study the effectiveness of third-party trust seals that have emerged as a prominent mechanism to enhance trust in B2C online markets. Despite their common use by practitioners, systematic research studies of the effectiveness of trust signals are scarce. Exploiting a unique dataset of over a quarter million transactions across 493 online retailers, this study empirically measures the value and effectiveness of trust seals on the likelihood of purchase by shoppers. The dataset is collected from a randomized field experiment by a large trust seal provider, which enables us to infer the causal impacts of the presence of a trust seal. It is found that the presence of the online trust seal increases the odds of completion of purchase. I further find that online trust seals serve as partial substitutes for both shopper experience and seller size, which makes the seal more useful for first time visitors at a web site and also for smaller online retailers. Interestingly, the effect of the number of trust seals is subject to diminishing marginal returns, such that the presence of additional seals does not necessarily increase cart completion rates.

    THE IMPACT OF CULTURAL DIFFERENCES ON BUYER-SUPPLIER RELATIONSHIPS.
    (2010) Ribbink, Dina; Grimm, Curtis M; Business and Management: Logistics, Business & Public Policy; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)
    In today's economy, an ever-increasing number of companies are dealing with partners from across the world giving rise to the need to understand the impact of cultural differences on business interactions. This dissertation uses two different approaches to investigate the impact of culture in buyer supplier relationships. The first study researches the effect of cultural differences in contractual buyer-supplier agreements using transaction cost as a theoretic lens. A large number of relationships translate into contracts between partners, but very few studies have investigated the effect of cultural differences on these written agreements: This research looks at the level of contract completeness and the option to renegotiate the contract as outcome variables. The study investigates the impact of cultural difference in buyer-supplier relationships using Hofstede's cultural dimensions. The main finding is that contract completeness increases as the cultural gap between the buyer and supplier widens. The results for individual culture dimensions on contract completeness are mixed. Cultural distance impacts the option of renegotiation but the individual dimensions fail to have an effect. Finally, asset specificity has the expected positive effect on the level of contract completeness and the option to renegotiate, while more frequent transactions result in lower levels of contract completeness and fewer options to renegotiate. Overall, these findings emphasize that cultural background is a factor in contractual buyer supplier relationships and need to be taken into account in global supply chain management. The second essay investigates the impact of cultural differences in the context of dyadic buyer-supplier negotiations. It looks at the moderating effect of culture. The study uses an experimental design to investigate these issues. In the simulation negotiation, participants, classified by their country of origin, are asked to take on the role of either a buyer or a seller. They negotiate prices and quality levels for three products. This study finds that cultural differences within the negotiation dyad reduce joint profits when compared to dyads of participants with similar cultural backgrounds. Cultural differences weaken the effect of trust and opportunism on joint profits. Overall, this study concludes that cultural differences as encountered in day-to-day business interactions in global supply chains impose greater challenges.

    Joint Replenishment and Supply Chain Actions in the Retail Grocery Industry: Two Essays
    (2006-09-15) Donovan, Pamela S.; Grimm, Curtis; Evers, Philip T.; Logistics, Business and Public Policy; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)
    This study investigated supply chain management practices in the retail grocery industry from two perspectives. First, the operational performance objectives were examined by developing and testing a periodic review, joint replenishment model and heuristic. Joint replenishment policies, designed to coordinate the ordering of multiple items, can reduce inventory costs by synchronizing transportation and replenishment decisions (Cetinkaya and Lee, 2000). A fully specified model was developed taking into account the cost disadvantage of over-declared shipments. Based on the performance of the Full model, a Truck heuristic was proposed to fill a truck with each order. By varying the model parameters, the study demonstrated the large impact transportation costs had on total inventory costs and the viability of the Truck heuristic, even for moderate differences in transportation rates. A simulation study tested violations of the demand normality assumption and found the Full model suboptimized the order interval and base stock levels under non-normal demand conditions. The result was a 2 percent cost increase over the expected costs in the Full model. The primary cost drivers were positive or negative deviations from truckload shipments and higher than expected demand during the order interval and replenishment period. The second essay examined the strategic objectives of the retail grocer using the Schumpeterian perspective to relate supply chain actions, market-based actions, and firm performance in a longitudinal study. A structured content method was used to code articles reporting on supply chain and market-based activities. The study found that higher levels of supply chain and market-based actions, a source of competitive advantage, resulted in higher sales growth. Unexpectedly, firms engaged in a broad range of supply chain activities realized a decline in sales, suggesting that a more narrow focus on specific supply chain programs provided greater financial benefits to firms in the retail grocery industry. An exploratory study using cluster analysis found grocery retailers used a variety of strategies. Larger firms were more likely to focus on market-based strategies and realized the largest sales growth. Smaller firms, on the other hand, tended to choose balanced or supply chain-focused strategies, while still realizing average sales growth.

    RISK MITIGATION IN THE SUPPLY CHAIN: EXAMINING THE ROLE OF IT INVESTMENT TO MANAGE SAFETY PERFORMANCE
    (2006-06-23) Cantor, David E.; Corsi, Thomas M.; Grimm, Curtis M.; Logistics, Business and Public Policy; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)
    Safety management in the supply chain is an interesting topic. The existence of unexpected supply chain events makes supply chain decision making difficult. To improve their response to unexpected events such as natural disasters or workplace accidents, managers are beginning to examine the link between information technology (IT) and safety in the supply chain. This dissertation examines the IT and safety link in three main ways. First, in the chapter entitled, "IT Investment and Safety: An Examination of The Impact of Information Technology on Safety Performance in a High Reliability Organization," drawing upon the work of Bharadwaj (2000), a theoretical model that links a firm's investment in IT resources to safety is developed. This model is empirically tested. A key finding is that physical IT resources, human IT resources, and growth in IT resources do contribute to safety performance. The second way that the IT and safety link is examined is through a U.S. Department of Transportation sponsored survey. In the chapter entitled, "Technology Adoption Patterns in the U.S. Motor Carrier Industry," a national survey is conducted to examine the safety technology adoption practices of larger trucking firms. The survey consists of twenty-six leading-edge safety technologies. A key finding is that larger trucking firms and firms that travel long distances are leaders in IT investment. Drawing on the resource-based view of the firm (RBV), the third way that the IT and safety link is examined is in the chapter entitled "Driving for Safety: An Examination of Safety Technology Adoption and Firm Safety Performance in the U.S. Motor Carrier Industry." The RBV framework describes how a firm's internal resources may be used to improve firm performance. Based on an over 50% survey response rate, a key finding is that safety technology resources do contribute to safety performance. It is also discovered that if the firm's top management team is knowledgeable about safety technology practices, the effect of safety technology resources on safety performance increases. Similarly, if the firm's IT staff has technology project management skills, the effect of safety technology resources on safety performance increases.

    DRIVERS OF ORGANIZATIONAL MODULARITY IN SUPPLY CHAINS - A CROSS SECTIONAL STUDY OF U.S. MANUFACTURING INDUSTRIES
    (2005-12-07) Cheng, Liang-Chieh; Grimm, Curtis M.; Dresner, Martin E.; Logistics, Business and Public Policy; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)
    This dissertation investigates the driving forces behind the emerging phenomenon of "organizational modularity", by which firms create "virtual" organizations through outsourcing functions, by using contract manufacturers, by forming alliances, and by using temporary employment contracts, as they organize their activities within supply chains. Using transaction cost analysis as the overarching theoretical framework for the analysis, a number of hypotheses that relate industry structure to modularity are developed. A large scale industry-level data set is used to test the hypotheses. Statistical results show that heterogeneity of supply sources, and scale economies in focal and downstream industries, are positively associated with greater use of modular forms, whereas other factors, such as the concentration of upstream and downstream industries, are associated with less modularity. In the current outsourcing environment, these findings provide crucial insights to capture the dynamics of the prevalent modular networks.
