Gjerstad, S. and Smith V.

Overspending in great amounts over long periods is facilitated by overlending by banks.  Neither banks nor entrepreneurs know the reason for, and the correct interpretion of, rising prices.

Previously I have suggested a lack of adaptation in the free economies to the requirements of the pure cycle.  …It is an inability to distinguish between the significance of a relative and an absolute rise or fall of monetary prices.  … the rising prices of the surplus expansion are not real and relative but only monetary and absolute rising prices; to allow them to stimulate production is to convert the surplus expansion into a boom (which must be followed out of systematic necessity by a correlative and devastating bust).  This I believe is the fundamental lack of adaptation to the productive cycle that our economies have to overcome. [CWL 15, 139-140]
