The critic is not causeless because it is assumed that tempo effects cause a distortion of the conventional period life expectancy even if mortality is changed. The major aim of this dissertation is the analysis of shifted deaths which are assumed to cause the occurrence of tempo effects. The results are important for the understanding of the general mechanism of the occurrence of tempo effects and their influence on measuring period mortality conditions.
