The publisher of Management Decision is issuing an expression of concern for the following article by Ulrich, K., Guaita Martínez, J.M., Carracedo, P. and Soriano, D.R. (2023), “Blockchain technology-based crypto assets: new insights into the evolution of the understanding of digital entrepreneurship”, Management Decision, Vol. 62 No. 9 pp. 2836-2854, doi: https://doi.org/10.1108/MD-03-2023-0306, which was submitted to the guest-edited special issue “Navigating the role of circular economy in entrepreneurship: Opportunities and challenges”. An investigation by the publisher found a number of articles with multiple concerns, including but not limited to compromised editorial handling and reviewing, undisclosed conflicts of interest and lack of suitability for the scope of the journal. As a result of these concerns and as trust in the content is central to the integrity of the publication process, the Editor-in-Chief and publisher have taken the decision to publish an expression of concern for all articles within this special issue. The journal has not been able to confirm whether the authors were aware of these concerns. The authors of this article would like to note that they do not agree with the content of this notice. An investigation is ongoing and is currently unresolved. Further information will be provided by Management Decision as it becomes available.
