在低收入国家，劳动生产率在很大程度上取决于人均消费，而人均消费有助于提供良好的营养、健康和教育。较高的人均消费水平提高了每个劳动者的劳动生产率。这种生产性消费的概念首先由Steger（J Econ Dyn Control（2002）26：1053-1068）在总量增长模型中制定，并使用数值模拟进行分析。在本章中，我们通过将Steger的模型扩展到两部门模型来研究生产性消费的劳动效率模型的稳定性。我们发现一个稳定态是唯一存在的，并且是鞍点稳定的，为Steger的模拟结果提供了理论支持。
In low-income countries, labor productivity crucially depends on per capita consumption that contributes to good nutrition, health, and education. A higher level of per capita consumption improves each worker’s labor productivity. This concept of productive consumption was first formulated in the aggregate growth model by Steger (J Econ Dyn Control (2002) 26:1053–1068) and analyzed using numerical simulations. In this chapter, we investigate the stability of the labor-efficiency model of productive consumption by extending Steger’s model to a two-sector model. We find that a steady state uniquely exists and is saddle-point stable, providing theoretical support for Steger’s simulation results.
