[Studies on the three-generation contract]

This publication contains three papers on the relationship between demographic trends particularly declining fertility and problems involving social security and the dependency burden. All of the papers have been previously published. The geographic focus is on the Federal Republic of Germany and other developed countries. The need to consider three generations (the young the working-age population and the elderly) when studying such problems is stressed. Individual papers deal with the demographic conditions for optimizing the economic burden on the economically active population changes in the relationship between the child and old-age dependency burdens and demographic changes as a problem for the social security system.
