Demographic change, altered work and living conditions, as well as increasing poverty among the elderly, present numerous challenges to the pension system. This leads to the question of what constitutes a fair pension being of existential importance for many people. But what does "fair pension" mean? This volume explores this question from a socio-ethical and interdisciplinary perspective, addressing various dimensions of justice. The guiding assumption is that reform approaches in the field of pension security can only be discussed based on an understanding of the normative claims associated with them.
