We propose a new interest rate rule that implements the optimal equilibrium and eliminates all indeterminacy in a canonical New Keynesian model in which the zero lower bound on nominal interest rates (ZLB) is binding. The rule commits to zero nominal interest rates for a length of time that...

Japan has experienced stagnation, deflation, and low interest rates for decades. It is caught in a liquidity trap. This paper examines Japan’s liquidity trap in light of the structure and performance of the country’s economy since the onset of stagnation. It also analyzes the country’s...

I give necessary and sufficient conditions under which interest-rate feedback rules eliminate aggregate instability by inducing a globally unique optimal equilibrium in a canonical New Keynesian economy with a binding zero lower bound. I consider a central bank that initially keeps interest...

We show that a .scal expansion by the core economies of the euro area would have a large and positive impact on periphery GDP assuming that policy rates remain low for a prolonged period. Under our preferred model speci.cation, an expansion of core government spending equal to one percent of...

We study the yield curve control in Eurozone. We apply Chen, Cúrdia and Ferrero (2012) model that uses a financial friction to break Wallace's neutrality. We calibrate a bond supply shock that corresponds to the observed change in the time premium in euro area when the APP program was...
