Wie stark sind unterschiedliche Bevölkerungsgruppen von der Inflation betroffen?

In Deutschland sind derzeit wieder so hohe Inflationsraten zu verzeichnen wie zuletzt im Wiedervereinigungsboom. Was sind die Ursachen dafür? Wie sind unterschiedliche Bevölkerungsgruppen davon betroffen? Wie sieht es in den anderen Ländern der Europäischen Währungsunion aus? Besteht die Gefahr einer Lohn-Preis-Spirale? Stehen wir vor einer erneuten Stagflation

The Econometric Foundations of Hedonic Elementary Price Indices

Hedonic methods are currently considered state-of-the-art for handling quality changes when compiling consumer price indices. The present article proposes first a mathematical description of characteristics and of elementary aggregates. In a following step, a hedonic econometric model is formulated and hedonic elementary population indices are defined. These indices extend from simple indices based on some average quality to universal formulae that incorporate the full quality spectrum of the respective elementary aggregate. We emphasise that population indices are unobservable economic parameters that need to be estimated by suitable sample indices. It is shown that most of the hedonic elementary index formulae used in practice are sample versions of particular hedonic elementary population indices
