We show a simple way to introduce monopolistic competition in a general equi- librium model where prices are fully flexible, the velocity of money is variable and cash-in-advance (CIA) constraints occasionally bind. We establish the conditions under which money has real e¤ects and demonstrate that an equilibrium that occurs at a binding CIA constraint is welfare inferior to any equilibrium that occurs at a non- binding CIA constraint with the same level of technology. We argue that even though the probability of a binding CIA constraint can be increasing with money supply, under certain conditions, expansionary money supply is welfare improving.
