Once New Keynesian (NK) theory (see, e.g., Woodford 2003) is combined with a standard model of investment (see, e.g., Thomas 2002), the resulting framework loses its ability to generate a realistic monetary transmission mechanism. This is the puzzle uncovered in Reiter et al. (2013). The simple...

Existing DSGE models are not able to reproduce the observed influence of international business cycles on small open economies. We construct a two-sector New Keynesian model to address this puzzle. The set-up takes into account intermediate trade and producer heterogeneity, where goods and...

There are two main approaches to modelling monetary policy; simple instrument rules and optimal policy. We propose an alternative that combines the two by extending the loss function with a term penalizing deviations from a simple rule. We analyze the properties of the modified loss function by...

We analyze the influence of the Taylor rule on US monetary policy by estimating the policy preferences of the Fed within a DSGE framework. The policy preferences are represented by a standard loss function, extended with a term that represents the degree of reluctance to letting the interest...

What are the consequences for monetary policy design implied by the fact that price setting and investment typically take place simultaneously at the firm level? To address this question we analyze simple (constrained) optimal interest rate rules in the context of a dynamic New Keynesian model...

There are two main approaches to modelling monetary policy; simple instrument rules and optimal policy. We propose an alternative that combines the two by extending the loss function with a term penalizing deviations from a simple rule. We analyze the properties of the modified loss function by...

The lumpy nature of plant-level investment is generally not taken into account in the context of New Keynesian monetary theory (see, e.g., Christiano et al., 2005; Woodford, 2005). Our main result shows that if this theory is augmented by a standard model of lumpy investment, monetary policy shocks...

In the presence of capital accumulation the Taylor principle may not be sufficient for determinacy under reasonable parameter values. In this paper I consider a two-sector extension of the models used in the existing literature. I show that what matters for whether the Taylor principle is...
