为福利国家、特别是公共退休养恤金筹措资金的日益困难，是生育率和出生率下降以及预期寿命延长的结果之一。在经济学中，养老金的动态变化通常使用重叠生成模型来研究。这些模型基于简化的假设，比如使用代表性的代理来缓解可处理性问题。另外，我们建议使用基于Agent的建模(ABM)，放松对这些假设的需要，并允许使用交互和异构Agent，特别重视对代际关系的研究。我们从经济学和政治的角度来看待养老金动态。我们所建立的模型，遵循奇数协议，将试图理解公共和私人退休养老金的选择动态，这是由于不同代理人的冲突偏好，但也是由于他们之间的合作。这些个人偏好的聚合是通过投票来完成的。我们将微观模拟方法与ABM方法相结合，以跟踪合成种群随时间的演化，并研究不同类型的agent之间的相互作用。我们的目标是从利己和利他、个人和集体行为之间的关系中描述公共养老金制度的生存条件。

英文摘要：
The increasing difficulties in financing the welfare state and in particular public retirement pensions have been one of the outcomes both of the decrease of fertility and birth rates combined with the increase of life expectancy. The dynamics of retirement pensions are usually studied in Economics using overlapping generation models. These models are based on simplifying assumptions like the use of a representative agent to ease the problem of tractability. Alternatively, we propose to use agent-based modelling (ABM), relaxing the need for those assumptions and enabling the use of interacting and heterogeneous agents assigning special importance to the study of inter-generational relations. We treat pension dynamics both in economics and political perspectives. The model we build, following the ODD protocol, will try to understand the dynamics of choice of public versus private retirement pensions resulting from the conflicting preferences of different agents but also from the cooperation between them. The aggregation of these individual preferences is done by voting. We combine a microsimulation approach following the evolution of synthetic populations along time, with the ABM approach studying the interactions between the different agent types. Our objective is to depict the conditions for the survival of the public pensions system emerging from the relation between egoistic and altruistic individual and collective behaviours.
