A parergon written with an open wink concludes the anthology. Udo Broll and Bernhard Eckwert identify "The fundamental Helmedag-constant" and shed light on the analogy between solutions to selected economic problems, e.g. in determining the "fair" wage, and the "golden ratio", as highlighted by the jubilarian in his own analyses. They postulate a comparability with the cosmological constant of astrophysics and transfer the findings to the presumed (practical) relevance of theoretical economic publications. According to the undoubtedly not really serious assessment of the (confessing) mainstream authors, then about 70% of the existing research work belongs to the "dark" neoclassical "matter" and only 30% to the visible and usable material. It cannot be assumed that the authors will succeed with their presentation, but they reveal – not only between the lines – their sincere appreciation for the academic life's work of the laureate.
