Optimal growth models aim at explaining long run trends of growth under the strong assumption of full efficiency in the allocation of resources. As a result, the steady state time paths of the main economic aggregates reflect constant, exogenous or endogenous, growth. To introduce business...

This paper develops and estimates a simple New Keynesian Dynamic Stochastic General Equilibrium (DSGE) model with rule-of-thumb consumers and external habits. Our theoretical model has a closed-form solution which allows the analytical derivation of its dynamical and stability properties. These...

Support for the Taylor principle is considerable but the focus of empirical investigation has been on estimated coefficients at the mean of the interest rate distribution. We offer a new approach that estimates the response of interest rates to inflation and the output gap at various points...

We test for mean reversion in real exchange rates using a recently developed unit root test for non- normal processes based on quantile autoregression inference in semi-parametric and non-parametric settings. The quantile regression approach allows us to directly capture the impact of...

This paper tries to assess the proximity of the macroeconomic outcomes which could arise from a monetary policymaking process based upon either a robust control or a Bayesian (à la Brainard) approach towards parameter uncertainty. We use a small, structural, backward-looking, aggregate model of...

This paper evaluates optimal monetary policy rules within the context of a dynamic stochastic general equilibrium model estimated for the Euro Area. Under assumption of an ad hoc loss function for the central bank, we compute the unconditional losses both under discretion and commitment. We...

The real interest rate gap -IRG-, i.e. the gap between the short term real interest rate and its “natural†level, is a theoretical concept of potential policy relevance for central banks, at least to evaluate the monetary policy stance, at best as a guideline for policy moves. This...

We study in a VAR model the effects of monetary policy shocks with new Italian flow of funds data for 1980-2002. First, our results are consistent with the literature, without being affected by commonly found puzzles. Second, new features of the transmission of monetary policy shocks to the...

This paper develops an arbitrage-free macroeconomic model of the yield curve and uses this to explain the behaviour of the UK Treasury bond market. Unlike previous models of this type, which assume a homoscedastic error process I develop a general affine model which allows volatility to be...

We compare three methods of motivating money in New Keynesian DSGE Models: Money-in-the-utility function, shopping time and cash-in-advance constraint, as well as two ways of modelling monetary policy, interest rate feedback rule and money growth rules. We use impulse response analysis, and a...
