本文提供了一种政治经济理论，解释当公民的寿命与经济发展过程共同决定时，经济如何演变。我们提出了一种三期重叠一代模型，其中主体的决策包含两个维度：关于教育的私人选择和关于创新政策的公共选择。我们发现，（a）人力资本积累中可能会出现贫困陷阱，（b）较高的预期寿命增加了年轻人和成年人创新的动力，（c）根据内生人口结构可能会出现不同的政治格局，（d）稳定状态可以容纳创新和创新的缺失。
This paper provides a politico-economic theory that explains how an economy evolves when the longevity of its citizens is jointly determined with the process of economic development. We propose a three-period overlapping generation model where agents’ decisions embrace two dimensions: a private choice about education and a public one on innovation policy. We find that (a) poverty traps can emerge in human capital accumulation, (b) higher life expectancy increases the incentive to innovate for both young and adults, (c) different political configurations can arise depending on endogenous demographic structures and (d) the steady state can entertain both innovation and its absence.
