We use a simple model of a closed economy to study the recommendations of monetary policy-makers attempting to respond optimally to an asset-price bubble whose stochastic properties they understand. We focus on the impact which the zero lower bound (ZLB) on nominal interest rates has on the...

We present a simple macroeconomic model that includes a role for an asset-price bubble. We then derive optimal monetary policy settings for two policymakers: a skeptic, for whom the best forecast of future asset prices is the current price; and an activist, whose policy recommendations take into...

The output gap is of central interest to policymakers. Being unobservable, however, its estimation is prone to error, particularly in real time. Errors result from revisions to the data and unavoidable end-point problems associated with the econometric techniques used to estimate it. This is the...

Almost a decade ago David Gruen and Geoff Shuetrim constructed a small macroeconomic model of the Australian economy. A comprehensive description of this model was subsequently provided by Beechey <em>et al</em> (2000). Since that time, however, the model has continued to evolve. This paper provides an...

This paper is the second of two companion pieces. In the first we developed a model of competition between payment systems which extends that of Chakravorti and Roson (2006). Here we turn to the results which can be obtained from the Chakravorti and Roson model, from our extension of it, and...
