Subjective Analysis of Price Herd Using Dominance Rough Set Induction: Case Study of Solar Companies

摘要

Herd behavior depends on subjectivity and objectivity combination. Usually the former over controls the latter and makes a special distinction from others. Especially, herd could regard itself as objective thus sacrificing all differences. Getting insight of the subjectivity appears more and more important in economics. However, the combination of subjectivity and objectivity varies with time evolution. To illustrate subjective analysis, we propose an inferential model to distinguish special enterprises from price herds. It assumes public finance as intrinsic self of subjectivity and the herding behavior as objective expectation of majority then identifies subjective actions.
