题目：Money, Unit ofAccount, and Nominal Rigidity

摘要：In order tocharacterize the properties required to fulfill the roles of money as a unit ofaccount (UoA) as well as a medium of exchange (MoE), we consider the choice ofa UoA in the context of a micro-founded model where inflation uncertaintyexists and some conversion cost is incurred in using a UoA that is different froman MoE. We show that it is not the level of inflation but its volatility that mattersfor the choice of a UoA. In the presence of inflation uncertainty, money canstill become both an MoE and a UoA as long as the conversion cost is higher thanits maximum buyers are willing to bear for ensuring stable consumption againstinflation uncertainty. Also, the choice of a UoA in the presence of fiat moneyas an MoE determines endogenously the nominal price rigidity or flexibility. Aneconomy adopting money as a UoA yields the short-run nominal rigidity and thePhillips-curve relationship.
