本说明在一个泥粘土框架中研究劳动力市场的动态。它分析了在没有市场摩擦的经济中创造就业和破坏就业的演变。失业和劳动力市场流动出现在泥粘土技术下，因为低生产率的工作成为未使用的因素。随着资本的积累，企业通过淘汰来摧毁低生产率的工作。同时，资本密集型技术的使用通过资本与劳动力之间的低替代性创造了新的就业岗位。
This note studies the dynamics of labor markets in a putty-clay framework. It analyzes the evolution of job creation and job destruction in an economy without market frictions. Unemployment and labor market flows emerge under putty-clay technologies because low productive jobs become unused factors. As capital accumulates, firms destruct low productive jobs by obsolescence. Simultaneously, the use of capital intensive technologies s new jobs by the low substitution between capital and labor.
