A modified version of the nominal contract developed by Gray (1976) an
d Fischer (1977) is introduced in a general equilibrium model with mon
ey which has been used in the real business-cycle literature. Money is
introduced in the model through cash-in-advance constraint. Two kinds
of contracts are examined, namely, a nominal wage contract and a nomi
nal price contract. The nominal wage contract improves the fit of the
model in many respects. The nominal price contract increases the outpu
t volatility enormously, but it has some unrealistic features.
