A Model of Bimetallism
Federal Reserve Bank of Minneapolis Research Department A Model of Bimetallism François R. Velde and Warren E. Weber Working Paper 588 August 1998 ABSTRACT Bimetallism has been the subject of considerable debate: Was it a viable monetary system? Was it a de- sirable system? In our model, the (exogenous and stochastic) amount of each metal can be split between monetary uses to satisfy a cash-in-advance constraint, and nonmonetary uses in which the stock of un- coined metal yields utility. The ratio of the monies in the cash-in-advance constraint is endogenous. Bi- metallism is feasible: we find a continuum of steady states (in the certainty case) indexed by the constant exchange rate of the monies; we also prove existence for a range of fixed exchange rates in the stochastic version. Bimetallism does not appear desirable on a welfare basis: among steady states, we prove that welfare under monometallism is higher than under any bimetallic equilibrium. We compute welfare and the variance of the price level under a variety of regimes (bimetallism, monometallism with and without trade money) and find that bimetallism can significantly stabilize the price level, depending on the covari- ance between the shocks to the supplies of metals.
