Liquidity Traps Gesell’s Solution

An economy is in a liquidity trap when monetary policy cannot influence either real or nominal variables of interest. A necessary condition for this is that the short nominal interest rate is constrained by its lower bound, typically zero. The paper develops a small analytical model to show how an economy can get into a liquidity trap, how it can avoid getting into one and how it can get out. To avoid the risk of falling into a liquidity trap, or to escape from one, the authorities can remove the zero nominal interest rate floor, by adopting an augmented monetary rule that systematically keeps the own nominal interest rate on currency below the nominal interest rate on non-monetary instruments. This involves paying interest, negative or positive, on certain government 'bearer bonds' -coin and currency, that is, 'taxing money', as advocated by Gesell. There are likely to be significant shoe leather costs associated with any scheme to tax currency. Willem H.
