The celebrated Taylor rule provides a simple formula that aims to capture how the central bank interest rate is adjusted as a linear function of inflation and output gap. However, the rule does not take explicitly into account the zero lower bound on the interest rate. Prior studies on interest...

The standard new Keynesian monetary policy problem is presentable as a set of linearized equations, for values of endogenous variables relatively close to their steady-state. As a result, only three possibilities are admissible in terms of long-term dynamics: the equilibrium may be a stable...

The standard new Keynesian monetary policy problem is, in its original presentation, a linear model. As a result, only three possibilities are admissible in terms of long term dynamics: the equilibrium may be a stable node, an unstable node or a saddle point. Fixed point stability (a stable...

We make a case for the usefulness of an optimal control approach for the central banks’ choice of interest rates in inflation target regimes. We illustrate with data from selected developed and emerging countries with longest experience of inflation targeting.

The paper reviews issues related to the zero lower bound (ZLB) on interest rates and argues that all of the following propositions are invalid: (1) in a ZLB situation, gshaping interest rate expectations is essentially the only tool that central bankers haveh (Bernanke, Reinhart, and Sack...

There is a case, but there are also counter-arguments. With sufficient forward-looking behaviour among firms and households, price-level targeting can act as a powerful built-in stabiliser through automatic shifts in inflation expectations. This stabilisation mechanism reduces the need for large...

This paper surveys the literature on monetary policy at the zero lower bound on nominal interest rates. Certain crucial insights regarding expectations have been neglected in recent research in this field. Taking this into account, the interactions between demand and supply shocks appear crucial...

This paper examines optimal exchange policy when nominal interest rates are unusually low, as experienced by several Asian economies and Japan since July 2006. The paper finds that in such environments, it is optimal to create a nominal depreciation to offset contractionary disturbances....

Can the central bank credibly commit to keeping the nominal interest rate low for an extended period of time in the aftermath of a deep recession? By analyzing credible plans in a sticky-price economy with occasionally binding zero lower bound constraints, I find that the answer is yes if...
