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 decline in output volatility in a number of countries over the past few decades has been well-documented, though less agreement has been reached about the causes of this decline. In this paper, we use a panel of data from 20 OECD countries to see if there is a role for various indicators of...

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...

Analysts typically use a variety of techniques to forecast inflation. These include both ‘bottom-up’ approaches, for near-term forecasting, as well as econometric methods (such as mark-up models of inflation, which have been found to perform quite well for Australia – see de Brouwer and...

In the wake of the global financial crisis a considerable amount of research has focused on integrating financial factors into macroeconomic models. Two common approaches for doing so include the financial accelerator and collateralised lending, examples of which are Gilchrist, Ortiz and...

This paper attempts to reconcile the high estimates of price stickiness from macroeconomic estimates of a New-Keynesian Phillips Curve (NKPC) with the lower values obtained from surveys of firms’ pricing behaviour. This microeconomic evidence also suggests that the frequency with which firms...

Policy-makers have recently noted an apparent flattening of the Phillips curve. The implications of such a change include that a positive output gap would be less inflationary, but the cost of reducing inflation, once established, would increase. This paper’s objective is to review the...

In this paper we develop a theoretical framework that helps to analyse the role of monetary policy in responding to asset-price bubbles. A large and rapid fall in the nominal price of assets that form the basis of collateral for loans from financial intermediaries can have adverse effects on...

This paper investigates the merits of aggregate inflation targeting compared with non-traded inflation targeting using a model of a small open economy producing traded and non-traded goods. An important innovation of our approach is that we isolate the effects of exchange rate, supply and demand...

We examine the relationship between the short-term volatility of the <em>effective</em> Real Exchange Rate (RER) and the degree of flexibility of the nominal exchange rate. Existing evidence demonstrates that the short-term variance of bilateral RERs is on average about 12 times higher under floating...
