概要 This study provides a theoretical basis heterogeneous agent-based microfoundation for the concept of ''the liquidity trap'' with a binary choice model, in which an economic agent stochastically changes her decisions. The model demonstrates that money holding becomes relatively advantageous as the proportion of money holders increases and that such a situation may bring about multiple equilibria. In particular, in analyzing the influences of heterogeneous expectations on the economy, the model offers a novel perspective about the monetary policy, demonstrating the effectiveness of unconventional monetary policies when the conventional ones are ineffectual.This study found the crucial fact that unconventional monetary policies work better than conventional ones in response to a crisis induced by a flight to liquidity.
