The Calvo contract Phillips Curve is widely indexed for general inflation, using either core inflation or other backward-looking formulae. Such a Phillips Curve implies a high and persistent degree of nominal rigidity. It is argued here that optimal indexation would by contrast use the rational...

We review the main New Keynesian inflation equations that have arisen as a result of aggregation from individual firms' price rigidities. We find that, on the whole, they cannot account for inflation persistence, a key feature of the empirical dynamics of inflation, and with important policy...

Explicit modelling of factor markets clarifies two fundamental aspects of the New Keynesian Phillips Curve (NKPC). First, we clarify the relationship between output and marginal cost. Second, for the NKPC in inflation-output space, we identify the key stochastic influences on inflation without...

Dieser Beitrag analysiert die Existenz und das Ausmaß nach unten starrer Nominallöhne, sowie deren realwirtschaftliche Implikationen für den deutschen Arbeitsmarkt. Unter Verwendung von drei alternativen Modellvarianten für die proportionale Abwärtsnominallohnrigidität wurde auf Grundlage...

How are inflation and unemployment related in the long run? Are they negatively correlated, as in the so-called naive Phillips curve theories or uncorrelated, "as in the neo-liberals' view or are they positively correlated as Friedman suggested in his Nobel lecture? <p> In this paper inflation is...</p>

In this paper we incorporate the two most prominent approaches of inequality aversion, i.e. Fehr and Schmidt (1999) and Bolton and Ockenfels (2000) into an otherwise standard New Keynesian macro model and compare them with respect to their influence on the long-run effectiveness of monetary...

We study micro price dynamics and their macroeconomic implications using daily scanner data from 1988 to 2013. We provide five facts. First, posted prices in Japan are ten times as flexible as those in the U.S. scanner data. Second, regular prices are almost as flexible as those in the U.S. and...
