This paper presents a small model of the Australian macroeconomy. The model is empirically based, aggregate in nature and consists of five estimated equations – for non-farm output, the real exchange rate, import prices, unit labour costs and consumer prices. The stylised facts underlying each...

This paper explores the extent to which Knightian uncertainty can explain features of interest rate paths observed in practice that are not generally replicated by models of optimal monetary policy. Interest rates tend to move in a sequence of steps in a given direction, or remain constant for...

In practice, monetary policy changes tend to produce a smooth path for interest rates while the path of policy interest rates generated by models is often considerably more variable. This paper investigates whether the inclusion of uncertainty can help reconcile the theory to the practice. It...

Standard solution methods for linear stochastic models with rational expectations presuppose a time-invariant structure as well as an environment in which shocks are unanticipated. Consequently, credible announcements that entail future changes of the structure cannot be handled by standard...

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...

We use the multi-sector and multi-country G-Cubed model to explore the potential role of three major shocks – to productivity, risk premia and US monetary policy – to explain the large movements in relative prices between 2002 and 2008. We find that productivity shocks were major drivers of...
