  • 演講摘要 : We show that expectations in existing tractable forward looking DSGE models at the lower bound are crucial, but conflict with Professional Forecaster's data. Accordingly, we study a class of DSGE models with one endogenous state where the lower bound endogenously binds for L>0 periods. We develop a unified framework to study impact policy multipliers in which Guerrieri & Iacoviello (2014)'s deterministic algorithm is a special case. We derive precise conditions for the deterministic multiplier to either converge/diverge with L. We develop a stochastic algorithm that always converges, which we apply to a DSGE model with habit formation that is consistent with expectations data.
