In times of climate change and public debt, a concern for intergenerational justice should lead us to have a closer look at theories of intergenerational justice. It should also press us to provide institutional design proposals to change the decision-making world that surrounds us. This book provides an exhaustive overview of the most important institutional proposals as well as a systematic and theoretical discussion of their respective features and advantages. It focuses on institutional proposals aimed at taking the interests of future generations more seriously, and does so from the perspective of applied political philosophy, being explicit about the underlying normative choices and the latest developments in the social sciences. It provides citizens, activists, firms, charities, public authorities, policy-analysts, students, and academics with the body of knowledge necessary to understand what our institutional options are and what they entail if we are concerned about today's excessive short-termism.

This chapter explores the specificities, strengths, and weaknesses of the idea of reciprocity as a basis for intergenerational obligations. Three models are presented: descending, ascending, and double reciprocity. Each of these three models is tested against three objections. The first objection asks why having received something from someone would necessarily entail the obligation to give back. The second objection questions the ability of each model to justify the direction of reciprocation. A final objection looks at the extent to which reciprocity-based views adjust the content of our obligation to the fluctuations in population size.
