We highlight how detrending within Structural Vector Autoregressions (SVAR) is directly linked to the shock identification. Consequences of trend misspecification are investigated using a prototypical Real Business Cycle model as the Data Generating Process. Decomposing the different sources of...

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...

In this paper we use a simple model of the Australian economy to empirically examine the consequences of parameter uncertainty for optimal monetary policy. Optimal policy responses are derived for a monetary authority that targets inflation and output stability. Parameter uncertainty is...

This paper examines optimal monetary policy in an open-economy two-country model with sticky prices. Currency misalignments are shown to be inefficient and lower world welfare. Also, optimal policy must target not only inflation and the output gap, but also the currency misalignment. However,...

We introduce financial market friction through search and matching in the loan market into a standard New Keynesian model. We reveal that the second order approximation of social welfare includes the terms related to credit, such as credit market tightness, the volume of credit, and the loan...

We investigate a new source of economic stickiness: namely, staggered loan interest rate contracts under monopolistic competition. The paper introduces this mechanism into a standard New Keynesian model. Simulations show that a response to a financial shock is greatly amplified by the staggered...

This paper studies how monetary policy should respond to news about an oil discovery, using a workhorse New Keynesian model. Good news about future production can create a recession today under exchange rate pegs and a simple Taylor rule, as seen in practice. This is explained by forward-looking...
