Abstract
This note aims to empirically verify the control system model of profit rate established by Park and Yang [4]. Specifically, it is shown that the real profit rate has gradually fallen in 8 countries over the last several decades. Then, using the parameters estimated from the real data, the simulated profit rates are obtained from the control system model, and compared with the real profit rates. As a result, this note shows that although the short-run behaviors are different, the control system model well captures the long-run decline in profit rate for all countries.
本说明旨在对 Park 和 Yang [4] 建立的利润率控制系统模型进行实证验证。具体而言,研究表明在过去几十年中,8 个国家的实际利润率逐渐下降。然后,利用从真实数据中估算出的参数,从控制系统模型中得到模拟利润率,并与真实利润率进行比较。结果表明,虽然短期行为不同,但控制系统模型很好地捕捉到了所有国家利润率的长期下降趋势。
