The Kernel-Location Approach - A New Non-parametric Approach to the Analysis of Download Nominal Rigidity in Micro Data


  • Knoppik, Christoph


A new econometric approach to the analysis of downward nominal wage rigidity in micro data is proposed, the kernel-location approach. It combines kernel-density estimation and the principle of joint variation of location and shape of the distribution of per cent annual nominal wage changes. The approach provides partial estimates of the counterfactual and factual distributions, of the rigidity function and of the degree of downward nominal wage rigidity. It avoids problematic assumptions of other semi- or non-parametric approaches to downward nominal wage rigidity in micro data and allows a discussion of the type of downward nominal wage rigidity encountered in data. Der vorliegende Beitrag stellt einen neuen ökonometrischen Ansatz zur Analyse der Abwärtsnominallohnstarrheit in Mikrodaten vor, den sogenannten Kernel-Location-Approach. Dieser kombiniert die Schätzung der Kernel-Dichte und das Prinzip der verbundenen Variation von Lage sowie Form der Verteilung von prozentualen jährlichen Nominallohnänderungen. Der Ansatz liefert Teilschätzungen der kontrafaktischen und der faktischen Verteilungen, der Starrheitsfunktion und des Grades der Abwärtsnominallohnstarrheit. Er vermeidet problematische Annahmen anderer semi- oder nicht-parametrischer Ansätze zur Abwärtsnominallohnstarrheit in Mikrodaten und ermöglicht die Diskussion verschiedener Arten der in Daten anzutreffenden Abwärtsnominallohnstarrheit.
