The Taylor rule in combination with the zero lower bound on nominal rates has been shown to create an unintended liquidity-trap equilibrium. The relevance of this equilibrium has been challenged on the basis that it is not stable under least-square learning. In this paper, we show that the...

In standard solutions, the new-Keynesian model produces a deep recession with deflation in a liquidity trap. The model also makes unusual policy predictions: Useless government spending, technical regress, and capital destruction have large multipliers. These predictions become larger as prices...

The paper provides a formalisation of the monetary folk proposition that fiat base money is an asset of the holder but not a liability of the issuer. The issuance of irredeemable fiat base money can have pure fiscal effects on private demand. With irredeemable fiat base money, weak restrictions...

We examine global dynamics under infinite-horizon learning in New Keynesian models where the interest-rate rule is subject to the zero lower bound. As in Evans, Guse and Honkapohja (2008), the intended steady state is locally but not globally stable. Unstable deflationary paths emerge after...

In this paper we consider a two-country New Open Economy Macroeconomics model, and analyze the optimal monetary policy when countries cooperate in the face of a "global liquidity trap" - i.e., a situation where the two countries are simultaneously caught in liquidity traps. Compared to the...

Prevalent thinking about liquidity traps suggests that the perfect substitutability of money and bonds at a zero short-term nominal interest rate renders open-market operations ineffective for achieving macroeconomic stabilization goals. In an earlier paper, we showed that this reasoning does...

This paper analyzes a potential strategy for escaping liquidity traps. The strategy is based on an augmented Taylor-type interest-rate feedback rule and differs from usual specifications in that when inflation falls below a threshold, the central bank temporarily deviates from the traditional...

This paper studies the limitations of monetary policy transmission within a credit channel frame- work. We show that, under certain circumstances, the credit channel transmission mechanism fails in that liquidity injections by the central bank into the banking sector are hoarded and not lent...

I study monetary and fiscal policy in liquidity trap scenarios, where the zero bound on the nominal interest rate is binding. I work with a continuous-time version of the standard New Keynesian model. Without commitment, the economy suffers from deflation and depressed output. I show that,...

With integrated trade and financial markets, a collapse in aggregate demand in a large country can cause 'natural real interest rates' to fall below zero in all countries, giving rise to a global 'liquidity trap'. This paper explores the policy choices that maximize the joint welfare of all...
