Structural macroeconometric analysis and new HANK-type models with extremely high dimensionality require fast and robust methods to efficiently deal with occasionally binding constraints (OBCs), especially since major developed economies have again hit the zero lower bound on nominal interest...

Recent experience with interest rates hitting the effective lower bound and agents facing binding borrowing constraints has emphasised the importance of understanding the behaviour of an economy in which some variables may be restricted at times. The extended path algorithm is a commonly used...

This study investigates the interrelation between the household leverage cycle, collateral constraints, and monetary policy. Using data on the U.S. economy, we find that a contractionary monetary policy shock leads to a large and significant fall in economic activity during periods of household...

The paper analyses the effectiveness of fiscal tools at the zero lower bound (ZLB). A non-linear New Keynesian DSGE model with occasionally binding constraints on monetary policy and borrowing is applied. When the ZLB binds in a liquidity trap, government spending becomes more effective in...

Policy makers would like to prevent self-fulfilling fluctuations. Given the prevalence of occasionally binding constraints (OBCs) such as the zero lower bound (ZLB), this requires understanding the determinacy of models with OBCs. To this end, we derive existence and uniqueness conditions for...

Forward guidance as a tool of unconventional monetary policy can be highly efficient to support aggregate demand and to steer the economy out of the zero lower bound (ZLB). However, the effect that stimulates the economy can give rise to a time-inconsistency problem: if the central bank promises...
