艾亚加里模型中稳态多重性的证明

中文摘要 AI 辅助

本文首次解析构建了具有至少三个稳态的经典Aiyagari经济模型。过程中，针对储蓄净收益为负的情况，给出了稳态资本供给的新上下界；还提供了参数约束，确保存在一个稳态，其租金率接近一个简洁数值：资本份额乘以折旧率。

英文摘要

I provide the first analytic construction of a canonical Aiyagari economy exhibiting at least three steady states. Along the way, I provide new upper and lower bounds on the stationary capital supply for the case where the net return on saving is negative. I also give parameter restrictions that guarantee the existence of a steady state with a rental rate in the neighborhood of a remarkably simple number: the capital share times the depreciation rate.
