Steps toward identifying central bank policy preferences
This paper takes the parameters in central bank loss functions as fundamental preferences to be estimated from the data. It is these preferences (along with target values) that define the policy regime in operation and that potentially change with senior central bank appointments. Optimizing central banks apply policy rules whose feedback coefficients are functions of its preferences. Consequently, under some conditions, it is possible to back out estimates of the preference parameters from estimated policy reaction functions. This paper establishes conditions under which a policy regime can ...

Fixing the New Keynesian Phillips curve
This Economic Letter looks at the problems with the NKPC and discusses some alternatives that are increasingly being used to think about inflation and the monetary policy transmission mechanism.

The “inflation” in inflation targeting
Many central banks conduct monetary policy according to an inflation-targeting framework. Central to such a framework is the principle that monetary policy decisions are formulated in the context of an explicitly announced numerical target or range for some measure of inflation. Obviously, if an inflation-targeting framework is to be operational, then the important question of what measure of inflation to target cannot be avoided. There is unlikely to be a single answer to the question of which measure is best. And, indeed, inflation-targeting countries have varied significantly in the ...

Inflation targeting under commitment and discretion
Inflation targeting has been adopted by many central banks, but not by the U.S. Federal Reserve. Using an estimated New Keynesian business cycle model, I perform counterfactual simulations to consider how history might have unfolded if the Federal Reserve had adopted a form of flexible inflation targeting in the year Paul Volcker was appointed chairman. The first simulation assumes that the Federal Reserve could have tied its hands and committed once and for all; the second assumes that the Federal Reserve would have set policy with discretion. While the broad contours of historical ...

Methods for robust control
Robust control allows policymakers to formulate policies that guard against model misspecification. The principal tools used to solve robust control problems are state-space methods (see Hansen and Sargent 2006 and Giordani and Soderlind 2004). In this paper we show that the structural-form methods developed by Dennis (2006) to solve control problems with rational expectations can also be applied to robust control problems, with the advantage that they bypass the task, often onerous, of having to express the reference model in statespace form. Interestingly, because state-space forms and ...

Instability under nominal GDP targeting: the role of expectations
Ball (1997) shows using a small closed economy model that nominal GDP targeting can lead to instability. This paper extends Ball's model to uncover the role inflation expectations play in generating this instability. By changing the process by which inflation expectations are formed in the short-run aggregate supply curve we show that nominal GDP targeting in either level or growth form does not generally result in instability. We further show that in Ball's (1997) case where exact targeting causes instability that moving to inexact targeting restores stability.

Exploring the role of the real exchange rate in Australian monetary policy
An important issue in small open-economies is whether policymakers should respond to exchange rate movements when they formulate monetary policy. Micro-founded models tend to suggest that there is little to be gained from responding to exchange rate movements, and the literature has largely concluded that such a response is unnecessary, or even undesirable (Taylor, 2001). This paper examines this issue using an estimated model of the Australian economy. In contrast to micro-founded models, according to this model policymakers should allow for movements in the real exchange rage and the ...

Optimal simple targeting rules for small open economies
This paper solves for optimal policy rules in a stylized small open economy model under a spectrum of targeting regimes. These policy reaction functions are presented as feedback rules highlighting the dominant state variables in each rule. Optimal simple rules - rules that exploit a reduced information set - are explored to assess how much is lost when information is excluded from the optimal state-contingent rule. For the model analyzed we find that some optimal simple rules can approximate reasonably well the optimal state-contingent rule, these simple rules contain the real exchange rate. ...
