Iluzja pieniądza i motywacyjna wartość płac w świetle statystyki ekonomicznej

The article attempts to explore some of the associations between the theoretical terms of the expectancy theory of worker motivation and official data regarding wage statistics. Time series of decile indicators of nominal and real wages in Poland are analyzed in a manner similar to quantile regression. All decile indicators of nominal wages are rising, but the real value of the decile indicators rises only for the highest ones, while the rest is almost stagnant for the years 1992-2008. The described effects, being the necessary conditions of the money illusion, probably shape subjective expectancies in a different way not only for nominal and real wages, but also for high and low pay. Such a way of reasoning has not yet been found in the literature on the subject.
