Palmer, G.G.D. “The Rate of Interest in the Trade Cycle Theories of Prof. Hayek.” The South African Journal of Economics 23 (1955): 1–18.
“For many years the trade cycle theories of Prof. Hayek have been the centre of interest and controversy. His approach stands in contrast on the one hand to that of the purely monetary school of which R.G. Hawtree is the outstanding expert, and on the other hand to the Keynesians with their preoccupation with changes in the aggregates of Savings and Investment.”
