Dear Alatise Olufemi, It is totally control system based work. I was trying one time regarding this matter you ask for. I was try to model Indian Share Market with Controllability and Observability aspect towers the market prediction. But I was not get proper support from some economic subject known person. You may start this, it is very interesting. I think you first search some paper related to economy and control system. and try to review in this research area. Then definitely you may get some output of your question. Thank you...
