This paper documents the function and use of the Gretl function package VCwrapper.pdf that implements the VC method for estimating time-varying coefficients in linear models as described in Schlicht (2021). It builds on the VCC program by Schlicht (2021a), is easy to use and highly configurable....

The expansion of higher education in the Western countries has been accompanied by a marked widening of wage differentials and increasing overqualification. While the increase in wage differentials has been attributed to skill-biased technological change that made advanced skills scarce, this...

Wage Dispersion and Efficiency. It is often assumed that markets generate efficient allocations, but these are not necessarily fair. The widening of wage differentials that is currently observed is interpreted in this manner: Skill-biased technological progress increases demand for skilled work...

Trend extraction from time series is often performed by using the filter proposed by Leser (1961), also known as the Hodrick-Prescott filter. Practical problems arise, however, if the time series contains structural breaks (as produced by German unification for German time series, for instance),...

Internal organization relies heavily on psychological consistency requirements. This perspective has been emphasized in modern compensation theory, but has not been extended to organization theory. The idea is developed by starting from Williamson's discussion of idiosyncratic exchange. The...
