Abstract

The separation of a unit of account (UoA) from a medium of exchange (MoE) in the commodity-money system is investigated by considering explicitly a seller's choice of UoA in terms of either an MoE or a unit of metal weight. If the likelihood of debasement of an MoE and its rate are high enough, the price is posted in terms of a unit of metal weight rather than an MoE. Interestingly, this MoE-UoA separated equilibrium yields the flexible nominal price, whereas an MoE-UoA integrated equilibrium yields the sticky one. This implies the nominal price rigidity in the fiat-money system where MoE and UoA are integrated.
