Endogenous Cycles In A Simple Model With Lagged Externalities On Productivity


  • Keigo Nishida


This paper presents a simple model of endogenous cycles. In the model, working experience creates learning‐by‐doing externalities that improve labor productivity but it takes long time before the externalities come into effect. In addition, individuals have preferences with a subsistence consumption level. In the presence of the subsistence consumption requirement, a productivity increase generates the income effect that surpasses the substitution effect, and individuals choose to increase leisure time at the expense of supplying labor. The interactions between productivity changes through the lagged externalities and labor supply generate cycles endogenously. The model analysis shows that the dynamics exhibit cyclical fluctuations around a unique steady state.
