Dear all, Perhaps as a shameless plug, allow me refer to my own papers: Yukihiro Ikeda,Roscher's Grundlagen in the History of Economic Thought, Journal of Economic Studies, vol. 22, No. 3/4/5, 1995. Yukihiro Ikeda, Carl Menger in the 1860s: Menger on Roscher's Grundlagen in Gerrit Meijer ed. New Perspectives on Austrian Economics, Routledge, 1995. Obviously Menger was deeply involved in Roscherian tradition. His Grundlagen was one of the most important sources in the formation of Menger's Grundsaetze, as I have shown in the above paper in the Routledge volume. But the relevance of Roscherian economics for Hayek--if any--is still an open question to my knowledge. Cheers. Yukihiro Ikeda
