Most central banks perceive a trade-off between stabilizing inflation and stabilizing the gap between output and desired output. However, the standard new Keynesian framework implies no such trade-off. In that framework, stabilizing inflation is equivalent to stabilizing the welfare-relevant...

This note proposes a full description of the Calvo price-setting model based on partial prices indexation and studies the interaction between partial indexation and trend inflation. We show that to use a hybrid version of the Phillips curve partly decreases the risks of overestimate due to the...

We provide new evidence on the fit of the hybrid Phillips curve based on indexation of prices to lagged inflation and trend inflation for the Euro area and the United States over the period 1970-2002. The GMM-West estimates suggest that (i) a full indexation scheme is not data consistent whereas...

Monetary policy is sometimes formulated in terms of a target level of inflation, a fixed time horizon and a constant interest rate that is anticipated to achieve the target at the specified horizon. These requirements lead to constant interest rate (CIR)instrument rules. Using the standard New...

This paper characterizes the optimal inflation buffer consistent with a zero lower bound on nominal interest rates in a New Keynesian sticky-price model. It is shown that a purely forward-looking version of the model that abstracts from inflation inertia would significantly underestimate the...

This paper analyzes the implications of heterogeneity in price setting for both price and inflation inertia. Standard models based on Taylor- or Calvo-style price setting usually assume ex-ante identical firms, while Calvo's approach implies only ex-post heterogeneity. While it is known that...

This paper considers whether the sticky information model of Mankiw and Reis (2002) can robustly deliver inflation inertia. I find that four features of the model play a key role in determining inflation inertia: the frequency of information updating, the degree of real rigidities, the nature...

This paper characterizes the optimal long-run rate of inflation, consistent with an occasionally binding zero lower bound on nominal interest rates, in a stochastic New Keynesian sticky-price model calibrated to the U.S. economy. This may serve to inform discussions on the design of an...
