This article proposes a historical assessment of harmonic analysis of business cycles and its ability to both decompose and build cycles, as received at the Moscow Conjuncture Institute. It traces how the Fourier transform arrived at the Institute, mediated by Henry L. Moore, in the works and actions of Albert Vainshtein, Nikolai Chetverikov, and Nikolai Kondratiev, ultimately leading to Eugen Slutsky's well-known 1927 article The Summation of Random Causes as the Source of Cyclic Processes.

... hough the evidence does not warrant the assumption that there was an orchestrated effort at the Institute to push forward a research agenda on harmonic analysis of business cycles, it certainly unfolded as more than the summation of random events and individual incursions. Moreover, the Institute as a whole could have produced much more on this matter if it had escaped Stalinist oppression for at least a few more years.
