An unexpected shortage of banknotes emerged during 1992 in the former
Soviet Union. The cash shortage is explained by the asymmetry in the m
onetary union that prevailed, under which one member, the Russian Fede
ration, controlled banknote production while every member could create
deposit money. Adjustments in interest rates or the cash-deposit exch
ange rate could have mitigated the shortage. The possible efficiency c
osts of the cash shortage are explored. (C) 1996 Academic Press, Inc.
