7. Limitations and further research
We gained insights through an iterative Delphi panel of researchers from the review board of three prestigious journals coupled with literature review and post hoc discussions. Although the participants represented a wide range of countries, there is a North American bias with 56.41% of the panel coming from the US and Canada. From the pool of 269 reviewers, only 74 (27.51%) belong to countries outside North America. Therefore, our sample is more harmonious than the output of a random procedure. This study has a lesser level of Eastern (i.e., Asia) representation, with only two participants from China and South Korea. International experience of the Delphi panel offsets this issue to some extent. We acknowledge that the study depicts a view more representative of the Western developed economies. Eastern thinking and practice are important and have created new business models, including e-commerce clusters (e.g., Alibaba). Hence, this is direction for future research and the perspective could be analyzed separately or integrated in a comparative regional study. In addition, as discussed earlier, more work is needed to identify the methods that better fit to close the theory/practice gap and to understand the role played by intermediaries (i.e., consultants) in the dissemination of scholarly models and theories. We hope that this study will inspire researchers to develop more advanced and relevant theories of B2B marketing. Judging by the richness of the proposed research agenda, the future of B2B marketing is promising.
