Escaping a Liquidity Trap: Keynes’ Prescription Is Right But His Reasoning Is Wrong

  • Harashima, Taiji

Abstract

Keynes’ original intention in introducing the concept of a liquidity trap was to explain the reason why persistent large amounts of unutilized resources were generated during the Great Depression. This paper shows that this type of phenomenon cannot be explained in the framework of a traditional competitive market equilibrium. Instead, it can be understood in terms of a Nash equilibrium consisting of strategies of choosing a Pareto inefficient transition path because a Nash equilibrium can conceptually coexist with Pareto inefficiency. Such a Nash equilibrium will be selected when an upwards time preference shock occurs. At this Nash equilibrium, monetary policies are useless but fiscal policies are very effective as Keynes argued, but for different reasons.
