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.
Electronic money (e-money), as a network good, could become an important form of currency in the future. Such a development could affect monetary policy effectiveness. If an increased use of e-money substantially limits the demand for central bank reserves, this limitation would require changes in the central bank operational target and a closer coordination of monetary and fiscal policies. Also, the optimal size of monetary unions would be different. However, the current level of e-money use does not seem to pose a threat to the stability of the financial system. Thus, central banks can successfully implement the objectives of monetary policy.
