In this paper we empirically investigate the time- and state-dependent behavior of aggregate price setting. We implement a testing procedure by means of a nonparametric representation of the structural form New Keynesian Phillips curve. By means of the so-called functional coefficient regression...

Persistently high unemployment rates in Germany have led to a long-running controversy on the causes of the unemployment problem. This paper aims to re­view the contribution of Keynesian and monetarist theories to this controversy and explores empirically their implications for the explanation...

Der Aufsatz untersucht einige populäre Methoden zur Messung des Output Gaps auf der Basis von aggregierten Daten für die Euro-Zone. Obwohl die Methoden einige wichtige gemeinsame Eigenschaften aufweisen, zeigen sie auch erhebliche Unterschiede; insbesondere ist die Korrelation zwischen...

A growing body of empirical evidence shows that there exists a long-run positive tradeoff between inflation and real macroeconomic activity. Within a New Keynesian framewok, we examine how increasing returns generate a positive long-run relation between inflation and output.

The main purpose of this paper is to merge together two strands of the literature regarding, either directly or indirectly, inflation: the PPP and the Phillips curve ones. In order to accomplish this task, this contribution applies the tools of the Empirical Growth Literature and of Dynamic...

This paper analyzes the cost of disinflation under real wage rigidities in a micro-founded New Keynesian model. Unlike Blanchard and Galí (2007) who carried out a similar analysis in a linearized framework, we take non-linearities into account. We show that the results change dramatically, both...

The New Keynesian Phillips curve (NKPC) has become the dominant model on inflation dynamics. Moreover, a large body of empirical research has documented in recent years price-setting behaviour at the individual level, which allows the assessment of the microfoundations of pricing models. It is...

We show that low trend inflation strongly affects the dynamics of a standard Neo-Keynesian model where monetary policy is described by a standard Taylor rule. Moreover, trend inflation enlarges the indeterminacy region in the parameter space, substantially altering the so-called Taylor...

This paper examines the evolution of the Phillips Curve (PC) for the Spanish economy since 1980. In particular, we focus on what has happened since the late 1990s. Since 1999 the unemployment rate has fallen by almost 7 percentage points, while inflation has remained relatively subdued around a...

Inflation and unemployment are central issues in macroeconomics. While progress has been made on these issues recently using models that explicitly incorporate search-type frictions, existing models analyze either unemployment or inflation in isolation. We develop a framework to analyze...
