Should central banks target producer price inflation or consumer price inflation in the setting of monetary policy? Previous studies suggest that in order to avoid real indeterminacy and self-fulfilling fluctuations, the interest rate rule for open economies should react to producer price...

This paper analyses the necessary and sufficient conditions to ensure that interest rate policy does not introduce real indeterminacy and thus self-fulfilling fluctuations into open economies. A key feature of the model is the incorporation of capital and investment spending into the analysis....

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...

Reconciling the high frequency of price changes at the micro level and their apparent rigidity at the aggregate level has been the subject of considerable debate in macroeconomics recently. In this paper I show that incorporating production chains in a standard New- Keynesian model replicates...
