=================== HES POSTING ===================== As to the diffusion of Slutsky's work in western writings: "The Summation of Random Causes as the Source of Cyclic Process", appeared in Russian in 1927 with English summary (later published in Econometrica, 1937). This was cited and elaborated by Ragnar Frisch: "Propagation Problems and Impulse Problems in Dynamic Economics", in Economic Essays in Honour of Gustav Cassel, 1933, pp. 198-9. I don't know whether this is the first reference in Western literature, but it seems older than Allen's paper.
