Empirical evidence suggests that goods are highly heterogeneous with respect to the degree of price rigidity. We develop a DSGE model featuring heterogeneous nominal rigidities across two sectors to study the equilibrium determinacy and stability under adaptive learning for interest rate rules...

No. I demonstrate that econometric estimations of nominal interest rate rules may tell little, if anything, about an economy's determinacy properties. In particular, correct inference about the interest-rate response to inflation provides no information about determinacy. Instead, it could...

Using an endogenous portfolio choice model, this paper examines how different monetary policy regimes can lead to different foreign currency positions by changing the cyclical properties of the nominal exchange rate. We find that strict inflation-targeting regimes are associated with a short...

Research with Keynesian-style models has emphasized the importance of the output gap for policies aimed at controlling inflation while declaring monetary aggregates largely irrelevant. Critics, however, have argued that these models need to be modified to account for observed money growth and...

We explore the role of interest rate policy in the exchange rate determination process. Specifically, we derive exchange rate equations from interest rate rules that are theoretically optimal under a few alternative settings. The exchange rate equation depends on its underlying interest rule and...

This paper estimates a monetary policy reaction function for the ECB over the period 1999-2009. To allow for a potential shift in interest rate setting during the financial crisis, we permit a smooth transition from one set of parameters to another. The estimates show a swift change in the...

In this paper, we provide determinacy conditions, i.e. conditions ensuring the existence and uniqueness of a bounded solution, in a purely forward-looking linear Markov switching rational expectations model. We thus settle the debate between Davig and Leeper (2007) and Farmer et al. (2010). The...

According to the Taylor rule, the Federal Reserve sets the funds rate based on an estimate of the economy's unutilized resources and the contemporaneous behavior of inflation. The primary policy prescription deriving from this view is that the Fed has failed to control inflation when it has not...

There are a few limits on interest rate rules in the textbook sticky price macroeconomic model. A central bank can even use a 'pure' rule that sets the interest rate arbitrarily. However, modern consumption and investment theory suggests that expectations of future output enter the IS schedule....

Monetary economists have recently begun a serious study of money supply rules that allow the Fed to adjustably peg the nominal interest rate under rational expectations. These rules vary from procedures that produce stationary nominal magnitudes to those that generate nonstationarities in...
