New research published in Science (Poore & Nemecek, 2018) analyzes land use in food supply chains. An astounding 3.1 billion ha reduction in land use could be possible by excluding animal products from current diets. That is an area equivalent to Australia + China + European Union + United States. The author also shows that animal products use about 83% of the world’s farmland and contribute about 57% of food’s different emissions, despite providing only 18% of our calories. These findings demonstrate that we need to shift from “company thinking” to “supply chain thinking” if we want to see the full picture.
Exports can be decomposed into a foreign value added (FVA) and a domestic value added (DVA) component. FVA is a key measure of the importance of global supply chains. It refers to the imported goods and services incorporated in a country’s exports. DVA relates to the contribution of a country’s own (i.e. domestic) factors of production. The 2018 World Investment Report, recently published by UNCTAD, shows that “[f]rom 1990 until 2010, the share of FVA in total exports rose continuously, contributing to the growth in global trade” and, “in the past decade, for the first time in 30 years, the growth […] has come to a halt, with the share of FVA declining to 30 per cent in 2017”. But what are the reasons for a declining importance of the “extended workbench” model? First, the model is based on arbitrage; however, the economic success of emerging countries has led to an increase in labor costs. Second, manufacturing in high-wage countries is becoming increasingly profitable due to recent advances in robotics.
Note: The following text refers to a previous version of the JCR impact factors. A more recent version are the 2018 JCR impact factors (see there).
More than many other management disciplines, SCM has been very successful to professionalize and reinvent itself. A good indication for this development are the 2017 JCR journal impact factors, which have just been released. Many, although not all, impact factors of SCM journals have improved. The journal with the highest impact factor among SCM journals and the seventh-highest one among more than 200 management journals is Journal of Supply Chain Management (6.105). Three SCM journals have impact factors between 4 and 5: Journal of Operations Management (4.899), International Journal of Production Economics (4.407) and International Journal of Physical Distribution & Logistics Management (4.215). IJPDLM is now even the Emerald journal with the highest impact factor, which is a great achievement! Two other SCM journals range between 3 and 4: Supply Chain Management: An International Journal (3.833) and Journal of Purchasing & Supply Management (3.667), but International Journal of Operations & Production Management (2.955) and Journal of Business Logistics (2.891) also come close to 3. Both International Journal of Logistics Management (1.776) and Decision Sciences (1.641) were able to improve their impact factors and get closer to 2. It might take some time until our journals will finally be acknowledged by qualitative rankings such as CABS’s AJG and VHB-JOURQUAL, as such rankings tend to be quite conservative. However, with such high impact factors there should be no doubt anymore that SCM plays in the same league as accounting, marketing and finance.
Putting efforts into high-quality reviews for academic journals has been a task of idealists so far. Unfortunately, these efforts are mostly invisible for appointment committees. That is a pity for two reasons: First, if researchers frequently receive review requests from good journals this indicates that they are respected by their research community. Second, if researchers accept such requests they demonstrate a willingness to develop and serve the research community. However, a relatively new tool, Publons, has the potential to make a change. Publons provides “a platform that allows researchers to track, verify and be recognised for their peer review and editorial work”. The good thing: “A researcher’s peer review and editorial contributions can be displayed on their public Publons profile to show the world the impact they have on their research field and enhance their career.” Publons often even tracks the length of submitted review documents and can even be used to create a verified review report, which can be included in job and funding applications.
The Journal of Business Logistics has a call for papers for a Special Topic Forum on Participating in the Wider Debate on Resilience (PDF). Submissions are due: June 1st, 2019. The editors for this JBL Special Topic Forum are Andreas Wieland (Copenhagen Business School) & Christian F. Durach (ESCP Europe Business School).
The circular economy is gathering momentum: In the future this model could, for example, mean that smartphones will not be sold and consumed anymore, but companies like Apple and Samsung will then keep scarce resources and sell a smartphone service to users instead of a product to consumers. These users will then be required to bring back the phone after a specified amount of time. California Management Review has now published a special issue on the circular economy. Several of the articles of that special issue refer to supply chains and supply chain management; and several of the authors have published in SCM journals before. This indicates that “supply chain thinking” and “circular thinking” are increasingly stimulating each other. I would even go so far to say that the 21st century’s supply chain management has to shift from linear to circular. This also has implications for our research. What we might need to re-think is whether the “chain” in “supply chain management” is still the right expression.
Some time ago, an editorial of Nature Human Behaviour has highlighted that “[the] quest for positive results encourages numerous questionable research practices […] such as HARKing (hypothesizing after the results are known) and P-hacking (collecting or selecting data or statistical analyses until non-significant results become significant)”. To counteract these very serious problems, that make theory-testing research almost useless, the journal has adopted the registered report format, which “shift[s] the emphasis from the results of research to the questions that guide the research and the methods used to answer them”. Similarly, the European Journal of Personality has recently announced to support the registered report format, too: “In a registered report, authors create a study proposal that includes theoretical and empirical background, research questions/hypotheses, and pilot data (if available). Upon submission, this proposal will then be reviewed prior to data collection, and if accepted, the paper resulting from this peer-reviewed procedure will be published, regardless of the study outcomes.” I can only hope that SCM journals will quickly catch up with this development in other fields.
A new research report, provided by Mighty Earth, argues that “[deforestation] is the result of a long supply chain that starts on the South American frontier and ends on European plates”. The report is titled The Avoidable Crisis. It reveals that a small group of companies controls the global agricultural trade: “These companies collectively control the majority of global grain trade […]. In addition to their role in trade, these companies also play a more direct role in driving ecosystem conversion by providing plantation owners with financing, fertilizer, infrastructure, and other incentives for new deforestation to expand their supply base. Given their outsized role, these companies have the power to insist that suppliers protect native ecosystems and land rights. But so far, these companies have prioritized reckless expansion over even easy conservation wins.” The authors argue that “[the] EU must send a strong signal to the market by requiring that companies implement measures for transparency and traceability into their supply chains”.
