I've wondered if it would be beneficial to apply some control systems theory to financial systems. But I'm not convinced that it would be applicable since control systems are designed for systems that follow the laws of physics. Financial systems include emotional responses and irrationality, how would control systems cope with that? P.S. I find it interesting that the majority of Chinese presidents from 1993 to 2010 have an engineering background.
