Microfoundations of dynamic new venture partnering capabilities

Stephan M. Wagner, Stefan Kurpjuweit

Journal of Business Logistics > 45 > 2 > n/a - n/a

Managing relationships with new venture suppliers require the adaptation of supplier management practices and routines. This research builds upon the dynamic capabilities perspective to explicate the ability to partner effectively with new venture suppliers as a dynamic capability. We argue that new venture partnering capability (NVPC) encompasses sensing, seizing, and transforming capabilities. Firms...

Sustainability‐related transgressions in global supply chains: When do legitimacy spillovers hurt buying firms the most?

Ivana Mateska, Christian Busse, Andrew P. Kach, Stephan M. Wagner

Journal of Supply Chain Management > 59 > 4 > 42 - 78

In a globalized world, buying firms increasingly face criticism regarding sustainability‐related transgressions in their supply chains, yet scholarship concerning whether such negative press has any bottom‐line effects has only just begun emerging. This study develops and tests theory on the relationship between reported supplier sustainability incidents and the associated stock price impact for the...

Just‐in‐time for supply chains in turbulent times

Thomas Y. Choi, Torbjørn H. Netland, Nada Sanders, ManMohan S. Sodhi, more

Production and Operations Management > 32 > 7 > 2331 - 2340

The Covid‐19 pandemic and other recent disruptions in the early 2020s led to sections in the business press blaming just‐in‐time (JIT) practices for operational failings. Consequently, there are calls for moving away from JIT toward holding more inventory as preparation against future disruptions, which is referred to as just‐in‐case. The academic community is also divided. Some scholars argue that...

Buyer abusive behavior and supplier welfare: An empirical study of truck owner–operators

Seongtae Kim, Sangho Chae, Stephan M. Wagner, Jason W. Miller

Journal of Supply Chain Management > 58 > 4 > 90 - 111

The increase in stakeholder pressure for responsible business draws closer public scrutiny when buyers use their power advantage illegitimately to exploit weaker suppliers. In this study, we develop the novel concept of buyer abusive behavior (BAB) and examine BABs exerted by buyers of trucking services against truck owner–operators as their suppliers. This focus is timely given the recent emergence...

When Blockchain Creates Shareholder Value: Empirical Evidence from International Firm Announcements

Maximilian Klöckner, Christoph G. Schmidt, Stephan M. Wagner

Production and Operations Management > 31 > 1 > 46 - 64

Blockchain is a prominently discussed technology in operations and supply chain management and firms increasingly engage in blockchain initiatives. Yet, an understanding of the technology's financial value remains elusive. Based on 175 firm announcements between 2015 and 2019, we conduct an international event study to estimate the impact of blockchain initiatives on the market value of the firm....

Examining the Stock Price Effect of Corruption Risk in the Supply Chain

Seongtae Kim, Stephan M. Wagner

Decision Sciences > 52 > 4 > 833 - 865

Although corrupt practices in the supply chain are not rare, this topic seems neglected in the literature. This could potentially be because a supply chain focused framework is lacking, and therefore it is difficult to measure the true impact of such issues. Why, how, and how much does corruption damage the corresponding firm in the supply chain? Our study takes what we term a supply chain view of...

Selecting Startups as Suppliers: A Typology of Supplier Selection Archetypes

Stefan Kurpjuweit, Stephan M. Wagner, Thomas Y. Choi

Journal of Supply Chain Management > 57 > 3 > 25 - 49

Recent research highlights opportunities to study collaborations between established firms and startups from a buyer–supplier relationship perspective. However, before firms can leverage startups’ resources and capabilities in a buyer–supplier relationship, they need to identify, evaluate, and select suitable startups as their suppliers. As prior research has only studied how buying firms select established...

Blockchain in Additive Manufacturing and its Impact on Supply Chains

Stefan Kurpjuweit, Christoph G. Schmidt, Maximilian Klöckner, Stephan M. Wagner

Journal of Business Logistics > 42 > 1 > 46 - 70

Additive manufacturing (AM) appears to be a particularly attractive use case for blockchain. This research combines inductive in‐depth interviews with the Delphi method to explore what potentials blockchain technology in AM creates, which adoption barriers firms need to overcome, and how supply chains will be affected by the integration of these two potentially disruptive technologies. The results...

Using Country Sustainability Risk to Inform Sustainable Supply Chain Management: A Design Science Study

Dagmar Reinerth, Christian Busse, Stephan M. Wagner

Journal of Business Logistics > 40 > 3 > 241 - 264

The sustainability of our global supply chains is an essential concern in strategic supply chain management research. Modern information and communication technologies enable stakeholders to punish buying firms for any sustainability‐related grievances at their suppliers, even in remote locations. This study investigates how the notion of country sustainability risk can inform sustainable supply chain...

How Supplier Economies of Scale Drive Supplier Selection Decisions

Florian Badorf, Stephan M. Wagner, Kai Hoberg, Felix Papier

Journal of Supply Chain Management > 55 > 3 > 45 - 67

Supplier selections are complex but nonetheless strategically important decisions that are influenced by numerous factors. Drawing on the resource‐based and relational view of the firm, we investigate how suppliers’ economies of scale influence the buyer's selection decision, and we illustrate how the influence of scale is contingent upon important economic, buyer, and relationship characteristics...

The Impact of Supplier Sustainability Risk on Shareholder Value

Seongtae Kim, Stephan M. Wagner, Claudia Colicchia

Journal of Supply Chain Management > 55 > 1 > 71 - 87

Business scandals like sweatshop labor have received growing attention in the field of supply management. Yet little is known about how detrimental such scandals are to buying firms. This study aims to fill this gap by examining the magnitude of the consequences of what are termed as supplier sustainability risks (SSRs). To this end, we conduct an event study analysis followed by regression modeling...

Simulation‐Based Optimization of Capacitated Assembly Systems under Beta‐Service Level Constraints

Stefan Woerner, Marco Laumanns, Stephan M. Wagner

Decision Sciences > 49 > 1 > 180 - 217

We study a class of capacitated assembly systems operated by base‐stock policies and address the problem of finding base‐stock levels that minimize holding costs under beta‐service level (fill rate) constraints over an infinite horizon. To solve this nonconvex constrained optimization problem, we develop a new simulation‐based optimization approach using the constrained level method (CLM) and infinitesimal...

Do what and with whom? Value creation and appropriation in inter-organizational new product development projects

Tingting Yan, Stephan M. Wagner

International Journal of Production Economics > 2017 > 191 > C > 1-14

Inter-organizational new product development (NPD) tasks vary in levels of uncertainty, hence, they might bring different levels of opportunities and risks to participating organizations. However, it is not well understood how an uncertain task context influences project-level value creation, a comprehensive concept which goes beyond short-term and tangible financial outcomes to also include long-term...

New Venture Partnering Capability: An Empirical Investigation into How Buying Firms Effectively Leverage the Potential of Innovative New Ventures

Boris W. Zaremba, Christoph Bode, Stephan M. Wagner

Journal of Supply Chain Management > 53 > 1 > 41 - 64

Drawing from the literature on firm resources and capabilities, as well as supplier management, this study investigates why and how some buying firms are more successful than others in leveraging the capabilities of their new venture suppliers. We use a qualitative research approach and synthesize our findings into a set of propositions that posit how buying firms manage their new venture suppliers...

Operational disruptions and business cycles

Stephan M. Wagner, Kamil J. Mizgier, Stylianos Papageorgiou

International Journal of Production Economics > 2017 > 183 > PA > 66-78

In the aftermath of the financial crisis, companies have advanced models for measuring and managing operational disruptions. However, the measurement and management approaches neglect the existence of business cycles. In this exploratory research, we investigate the relationship between business cycles and operational risk in two distinct U.S. industry sectors, namely financial services and manufacturing...

Design of Auction Parameters to Reduce the Effect of Collusion

Sidhartha S. Padhi, Stephan M. Wagner, Pratap K. J. Mohapatra

Decision Sciences > 47 > 6 > 1016 - 1047

Government departments are increasingly turning to auctions to procure goods and services. Collusion among bidders, however, reduces competition and raises winning bid prices. Since conventional collusion control measures based on the redesign of auction mechanisms are less effective in government procurement auctions, there is a need to devise control measures that decrease the effect of collusion...

Dominant Risks and Risk Management Practices in Supply Chains

Stephan M. Wagner, Christoph Bode

International Series in Operations Research & Management Science > Supply Chain Risk > Supply Chain Risk Management > 271-290

Supply chains are inherently susceptible to risky events. Earlier articles in supply chain management by Kraljic (1983) and Treleven, and Schweickhart (1988) stressed the importance to consider the risks arising from interconnected flows of material, information and funds in inter-organizational networks. However, during the last several years, the interest in this topic has significantly gained momentum...

Maneuvering through Hostile Environments: How Firms Leverage Product and Process Innovativeness

Andrew Kach, Christian Busse, Arash Azadegan, Stephan M. Wagner

Decision Sciences > 47 > 5 > 907 - 956

Is focusing on innovativeness the appropriate organizational response in hostile environments? This study addresses four distinct forms of hostile environments: market decline, restrictiveness, competition, and resource scarcity. The research draws on contingency theory to explain how these forms of hostility affect product innovativeness, process innovativeness, and firm performance. While the extant...

Supplier involvement in the fuzzy front end of new product development: An investigation of homophily, benevolence and market turbulence

Tobias Schoenherr, Stephan M. Wagner

International Journal of Production Economics > 2016 > 180 > C > 101-113

The fuzzy front end (FFE) of new product development (NPD), i.e. the phase preceding the formal product development, is characterized by ill-defined processes, ad-hoc decisions, equivocality and uncertainty. While involving suppliers in this early stage is crucial, limited insight exists on how to best accomplish this objective. We address this issue in the present research by focusing on two important...

Strategic and Operational Determinants of Relationship Outcomes With New Venture Suppliers

Boris W. Zaremba, Christoph Bode, Stephan M. Wagner

Journal of Business Logistics > 37 > 2 > 152 - 167

While the vast majority of the supplier selection and development literature has focused on relationships between mature, established firms, significantly less attention has been paid to relationships between established firms and new, entrepreneurial ventures. This study addresses this important topic and, using an interdisciplinary lens, investigates the question of how established buying firms...
