I just came across a very interesting bit of research, A Guide to Paradigmatic Self-Marginalization: Lessons for Post-Keynesian Economists by Leonhard Dobusch and Jakob Kapeller; you can find it here.
I realize this is not going to be of interest to many of our readers, as it is a sort of “inside the halls of academia” analysis. What the authors do is to look at the strategies of editors running the top orthodox and the top heterodox journals in economics. Actually it might be a bit unfair to label these strategies, as the authors do not mean to imply that editorial policy knowingly pursues the strategies. Instead, the article looks at the ex post results.
In a nutshell, what they find is that the articles published in orthodox journals do not cite the research published in heterodox journals. NO SURPRISE THERE! But they also find some startling self-defeating practices pursued by heterodox journals.
