Intergenerational justice has been achieved if the opportunities of the members of the next generation to fulfill their needs are better than those of the members of the preceding generation. For this, each generation ought to leave for the next generation an amount of resources is at least equal to its own amount. The book deals with the complex relationship between intergenerational justice and demographic change and is characterized by its interdisciplinary approach. The authors come from a multitude of professional backgrounds and from several countries. This illustrates the implications of the demographic shift from many different perspectives. The book deals not only with the aspects of economic policy but also with environmental, societal and philosophical issues. The comprehensive volume is composed of five sections that pinpoint demographic trends, examine the impact of demographic changes on key indicators, investigate the relationship between key indicators and intergenerational justice, scrutinize population policies, and finally propose ways to implement long-term thinking on these issues.
