The IMF Working Papers series is designed to make IMF staff research available to a wide audience. Almost 300 Working Papers are released each year, covering a wide range of theoretical and analytical topics, including balance of payments, monetary and fiscal issues, global liquidity, and national and international economic developments.
The introduction of a new currency has often occurred as part of a program to fight hyperinflation. In this context, non-uniform conversion rates for different types of assets and liabilities have been used as a means of reducing an initial “excess” stock of liquidity. The paper examines the anticipatory dynamics associated with such reforms. The analysis suggests that monetary reforms of this type have a deflationary effect upon announcement as well as during the transition period. Under uncertainty about the reform date, the direction of the initial jump in prices upon announcement is a priori ambiguous. Upon implementation, a monetary reform leads to a downward jump in prices.
