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....

This paper describes a moments estimator for a standard state-space model with coefficients generated by a random walk. The method calculates the conditional expectations of the coefficients, given the observations. A penalized least squares estimation is linked to the GLS (Aitken) estimates of...

This note gives a fairly complete statistical description of the Hodrick-Prescott Filter (1997) which has been proposed in the context of my seasonal adjustment method (Schlicht 1981, 1984). A statistics estimator for the smoothing parameter is proposed that is asymptotically equivalent to the...

Recent thinking has emphasized the importance of consistency in a firm?s compensation policy. By starting from Williamson?s ideas about idiosyncratic exchange, this view can be supplied with some theoretical foundation. At the same time, the consistency view can be applied to a number of...

It has been claimed that the market fosters selfishness and thereby undermines the moral basis of society. This thesis has been developed with an emphasis on market exchange. Everyday life is, however, predominantly shaped by interactions in the workplace rather than by shopping behaviour. This...

Consider a labour market with heterogeneous workers. Firms recruit workers by fixing a hiring standard and a wage offer simultaneously. A more demanding hiring standard necessitates a better wage offer in order to attract enough qualified applicants. As a result, an efficiency wage effect is...

This papers describes an estimator for a standard state-space model with coefficients generated by a random walk that is statistically superior to the Kalman filter as applied to this particular class of models. Two closely related estimators for the variances are introduced: A maximum...

Offering higher wages may enable firms to attract more applicants and screen them more carefully. If firms compete in this way in the labor market, selection wages emerge. This note illustrates this wage-setting mechanism. Selection wages may engender unconventional results, such as a pre-tax...

The expansion of higher education in theWestern 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...
