In this paper, I examine the role of monetary policy in a heterogeneous expectations environment. I use a New Keynesian business cycle model as the experiment laboratory. I assume that the central bank and private economic agents (households and producing rms) have imperfect and heterogeneous...

We analyze the economic dynamics in a basic New Keynesian model adjusted for imperfect, heterogeneous knowledge and adaptive learning. The policy, represented by a forward-looking Taylor rule, is driven by the central bank's own internal forecasts, whereas the core economic dynamics are driven...

Our discussion is structured by three concerns - model design, matching the data and operational requirements. The paper begins with a general discussion of the structure of dynamic stochastic general equilibrium (DSGE) models where we investigate issues like (i) the type of restrictions being...

The effect of oil prices on inflation has varied greatly in the last 50 years. Rising oil prices in the 1970s and early 1980s were associated with high and rising inflation. In the late 1980s and 1990s, however, the inflationary effect moderated. Although the experience of the energy crisis in...

We advance the proposal that DSGE models should not just be estimated and evaluated with reference to full information methods. These make strong assumptions and therefore there is uncertainty about their impact upon results. Some limited information analysis which can be used in a complementary...

DSGE models have become a widely used tool for policymakers. This paper takes the global identification theory used for structural vectorautoregressions, and applies it to dynamic stochastic general equilibrium (DSGE) models. We use this modified theory to check whether a DSGE model structure...

In this paper we review the evolution of macroeconomic modelling in a policy environment that took placeover the past sixty years. We identify and characterise four generations of macro models. Particular attention is paid to the fourth generation – dynamic stochastic general equilibrium...
