This paper examines the effect of a monetary shock in a stochastic gro
wth model with a cash-in-advance constraint and a financial intermedia
ry. It explores the differences between the results of restrictions on
nominal price adjustment (the demand effect) and restrictions on savi
ngs behavior (the liquidity effect). It is found that the model that p
roduces the appropriate response to a temporary monetary shock include
s both demand and liquidity effects.
