We build a life-cycle model in which a representative firm produces a final good using routine and non-routine labor as well as traditional and automation capital (e.g. robots). Robots can substitute for routine labor. We show that both, population aging and higher robot productivity, foster the increased use of robotics. Population aging decreases and progress in robot technology increases long-run output per capita. In both cases, inequalities in labor income, wealth and consumption rise. Although expected advances in automation technologies are able to mitigate or even circumvent output losses in the aggregate and improve consumption possibilities for everyone, this comes at the cost of increased inequality because non-routine workers benefit disproportionately.

我们建立了一个生命周期模型，在该模型中，代表公司使用常规和非常规劳动力以及传统资本和自动化资本（例如机器人）生产最终商品。机器人可以代替日常工作。我们表明，人口老龄化和更高的机器人生产率都促进了对机器人技术的更多使用。人口老龄化减少，机器人技术的进步提高了人均长期产出。在这两种情况下，劳动收入，财富和消费的不平等都会加剧。尽管自动化技术方面的预期进步能够减轻甚至避免总体上的产出损失并提高每个人的消费可能性，但这是以不平等现象加剧为代价的，因为非常规工人的收益不成比例。
