This paper presents a cash-in-advance model of the demand for money. M
oney demand depends on the transaction services of money as well as on
the risk and return properties of bonds in different currencies. The
paper shows how the money demand function changes with the adoption of
fixed exchange rates and monetary union, respectively. The model is t
hen calibrated for a monetary union between France and Germany as well
as between the Netherlands and Germany. The numerical results indicat
e substantial shifts in the behavior of the demand for money in respon
se to monetary integration. (C) 1998 Elsevier Science Ltd. All rights
