James Hamilton put doubt on the quality of the HP filter estimates, and proposed an alternative regression approach to decompose trend and cycle of time series (H filter). We investigate the new H filter in detail and compare it to the HP filter. We apply both to German GDP time series. We find...

This paper presents a simple illustrative post-Kaleckian model of distribution and growth that incorporates personal income inequality and interdependent social norms. The model shows in an easily accessible manner how personal and functional income inequality can potentially have contrary...

The gas price shock has been a major contributor to inflation in Germany. In this context, Dullien and Weber (2022a, b, c) proposed a two-tier pricing scheme for natural gas in the spring of 2022 that lowers the price for a base quota through a subsidy while maintaining high market prices on the...

This paper deals with a critical assessment and a reestimation of the "non-accelerating inflation rate of unemployment" (NAIRU) for Germany. There are quite a few obstacles to perceiving the NAIRU as an understandable and easy-to-use analytical instrument, suitable for economic policy: the...

Der Beitrag enthält eine Neuschätzung der inflationsstabilen Arbeitslosenquote (NAIRU) für Westdeutschland 1980 bis 1998. Nach einer Darstellung des konzeptionellen Rahmens der NAIRU einschließlich verschiedener Varianten, welche beispielsweise exogenen Schocks und dem Hysterese-Phänomen...

This paper provides new estimates of a time-varying NAIRU for Germany taking account of the structural break caused by German unification based on the Kalman Filter and on a partially linear model as two alternatives. Estimating a standard Phillips curve, the sum of coefficients associated with...

We use parametric power ARCH models of the conditional variance of inflation to model the relationship between inflation and its uncertainty using monthly data for Germany, the Netherlands and Sweden over a period ranging from 1962 to 2004. For all three countries inflation significantly raises...
