Concerns of prolonged near zero interest rates and below target inflation have become widespread in the advanced world. We build an analytical framework that incorporates two hypotheses of persistent ZLB episodes: expectations-driven liquidity traps and secular stagnation driven liquidity traps....

We explore the importance of the nature of nominal price and wage adjustment for the design of effective monetary policy strategies, especially at the zero lower bound. Our analysis suggests that sticky-price and sticky-information models fit standard macroeconomic time series comparably well....

This paper examines how and to what extent parameter estimates can be biased in a dynamic stochastic general equilibrium (DSGE) model that omits the zero lower bound constraint on the nominal interest rate. Our experiments show that most of the parameter estimates in a standard sticky-price DSGE...
