There has been a recent trend in several management disciplines, including supply chain management, to create knowledge by systematically reviewing available literature. So far, however, our discipline lacked a “gold standard” that guides researchers in this endeavor. The Journal of Supply Chain Management has now published our new article, Durach, Kembro & Wieland (2017): A New Paradigm for Systematic Literature Reviews in Supply Chain Management. Our systematic literature review process follows six steps: (1) develop an initial theoretical framework; (2) develop criteria for determining whether a publication can provide information regarding this framework; (3) identify literature through structured and rigorous searches; (4) conduct theoretically driven selection of literature and a relevance test; (5) develop two data extraction structures, integrate data to refine the theoretical framework, and develop narrative propositions; and (6) explain the refined framework and compare it to the initial assumptions. We believe that these best-practice guidelines, although developed for the SCM discipline, can be used as a blueprint also for adjacent management disciplines.

Trust plays an important role in supplier–buyer relationships. One way to approach this important concept is game theory. If you have ever wondered how game theory could be taught in a supply chain management course, I can recommend Nick Case’s The Evolution of Trust – an interactive guide to the game theory of why and how we trust each other. The guide starts by explaining the game of trust (= the prisoner’s dilemma). Then it illustrates what happens if multiple games and multiple tournaments are played with different players. We can learn from this guide that “the game defines the players” but also that “the players define the game”. We can learn that, in order for trust to evolve, we need the knowledge of possible future repeat interactions, we need a win–win situation, and we need a low level of miscommunication. I will definitely use The Evolution of Trust in my future supply chain management courses.
There seems to be a lot of confusion about what theory is. At least this is a recurring question I get from students. Let us first discuss what theory is not: Sutton & Staw (1995) show that “references, data, variables, diagrams, and hypotheses are not theory” and they “explain how each of these five elements can be confused with theory” (p. 371). But we should also be aware of the difference between facts and theory! In his essay, which is part of a collection of six essays, Pagell (in: Boer et al., 2015) paints the picture of an ideal research world where “most research will be building or testing facts, not theory”, while “theory building and testing [will be left] to a much smaller group of papers, where the theoretical argument would be critical” (p. 1244). So, what is theory? A definition I like comes from Suddaby (2015): “[T]heory is simply a way of imposing conceptual order on the empirical complexity of the phenomenal world” (p. 1).
I am pleased to announce that our new article, The Human Factor in SCM: Introducing a Meta-theory of Behavioral Supply Chain Management, which I co-authored with Timm Schorsch and Carl Marcus Wallenburg, has now been published by the International Journal of Physical Distribution & Logistics Management. Our article provides a comprehensive overview of the behavioral supply chain management (BSCM) research landscape. In addition, we present a meta-theory of BSCM that encompasses all central elements of the research field. We also formulate five promising future research opportunities: Research being conducted in this area could (1) integrate cognitive and social psychological research, (2) apply a holistic view to decision-making and problem solving, (3) strengthen the concept of emergence and apply meso-level theory approaches, (4) complement our meta-theory, and (5) broaden the scope of inventory and capacity decision-making. We are confident that the critical discussions in our article and the formulated research opportunities will help scholars in positioning their own research to enhance its contribution.

I recently found an interesting report: Value of Air Cargo: Air Transport and Global Value Chains, published by Developing Trade Consultants. The authors write: “Global Value Chains (GVCs) represent a new trade and development paradigm. They enable countries to specialize in narrowly defined tasks, such as component production, research and development, or assembly. Tasks originating in a variety of countries are then combined through a complex network of trade and investment links, to produce finished goods […].” The report analyzes data to investigate the linkages between GVC trade and air cargo. It shows that countries engage in more trade in value terms if they have better air cargo connectivity – which is measured by an “Air Connectivity Index”. A strong association is found between a higher ACI score (i.e. stronger air connections to more countries) and a higher total trade value: “[O]ne percent increase in air cargo connectivity is associated with a 6.3% increase in total exports and imports.”
