The decomposition of a given time series into trend, seasonal component, and irregular component is formulated as a minimization problem. The trend is chosen such that it is as smooth as possible; the seasonal component is chosen such that it exhibits a seasonal pattern as stable as possible; and...

This note, published in 1995, assesses the problems that might be entailed by the introduction of the European monetary union. It is argued that wage pressure will not be diminished by forming the union, and the stagflation problem that lies at the root of the rising trend in unemployment will...

The aim of this paper is to develop a model-based seasonal adjustment method which will yield the same decomposition formulas as the descriptive seasonal adjustment procedures proposed in Schlicht/Pauly (1984) and Schlicht (1981). Hence the duality between the descriptive and the model-based...

The seasonal adjustment method proposed by Schlicht (1981) can be viewed as a method that minimizes non-stochastic deviations (perturbations). This interpretation gives rise to a critique of the seasonality criterion used there. A new seasonality criterion is proposed that avoids these...

A labor market is considered that is characterized by job competition over job ladders. Firms paying more for comparable jobs can attract workers with better background characteristics (with general human capital) and will lose fewer trained workers (with general and firm-specific human...

The paper discusses a new seasonality hypothesis which is one part of a weighted regression approach for the decomposition of a time series into a trend, a seasonal component and an irregular component. It is shown that there exists a regression formulation leading, as in the descriptive...

A firm may reduce its turnover and the entailed turnover costs by raising wages. A rise in unemployment reduces turnover and turnover costs in a similar way. The interaction of these effects leads – in presence of perfectly flexible wages – to a stable equilibrium in the labor market which...
