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...

The output gap – the difference between actual and potential output – is widely regarded as a useful guide to future inflationary pressures, as well as an important indicator of the state of the economy in its own right. Since the output gap is unobservable, however, its estimation is prone...

Quarterly national accounts data are amongst the most important and eagerly awaited economic information available, with estimates of recent growth regarded as a key summary indicator of the current health of the Australian economy. Official estimates of quarterly output are, however, subject to...

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...

We present a simple model of the macroeconomy that includes a role for an asset-price bubble, and derive optimal monetary policy settings for two policy-makers. The first policy-maker, a sceptic, does not attempt to forecast the future possible paths for the asset-price bubble when setting...

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...
