We present determinacy bounds on monetary policy in the sticky information model. We find that these bounds are more conservative here when the long run Phillips curve is vertical than in the standard Calvo sticky price New Keynesian model. Specifically, the Taylor principle is now necessary...

It is commonly asserted that inflation is a jump variable in the New Keynesian Phillips curve, and thus wage-price inertia does not imply inflation inertia. We show that this "inflation flexibility proposition" is highly misleading, relying on the assumption that real variables are exogenous. In...

We argue that measurement error in historical price data has led researchers to erroneously believe that there was little persistence of inflation during the 19th century. Using a statistical technique that accounts for these errors, we estimate the persistence of (a) US inflation and (b)...

This paper studies the transition to high inflation during the COVID-19 pandemic, using a behavioral version of the New Keynesian model, which replaces the conventional assumption of Rational Expectations with subjective and heterogeneous expectations. Different shares of agents in the economy...

It is commonly asserted that inflation is a jump variable in the New Keynesian Phillips curve, and thus wage-price inertia does not imply inflation inertia. We show that this "inflation flexibility proposition" is highly misleading, relying on the assumption that real variables are exogenous. In...

Rational expectations models of staggered price/wage contracts have failed to replicate the observed persistence in inflation and unemployment during disinflation periods. The current literature on this persistency puzzle has focused on augmenting the nominal contract model with imperfect...

This paper uses disaggregated CPI time series to show that a break in the mean of French inflation occurred in the mid-eighties and that the 1983 monetary policy shift mostly accounted for it. CPI average yearly growth declined from nearly 11% before the break date (May 1985) to 2.1% after. No...

Challenging the conventional wisdom that structural problems are to blame for the euro area’s protracted domestic demand stagnation, this paper sets out to shed some fresh light on the role of the ECB in the ongoing EMU crisis. Contrary to the widely held interpretation of the ECB as an...

This chapter examines the concept of inflation persistence in macroeconomic theory. It begins by defining persistence — emphasizing the difference between reduced-form and structural persistence. It then examines a number of empirical measures of reduced-form persistence, considering the...

This paper employs the recently developed structural stability tests with unknown break point and two median unbiased estimation methods to model China inflation persistence over the most recent quarter of a century. Our empirical results suggest that the persistence of both consumer price...
