Using Fuzzy Game Theory on IPO's Pricing Behavior

The purpose of this research is to explore the IPO pricing behavior in an underwriting system by applying the fuzzy game theory. Results of this study are: (1) The application of the fuzzy game theory is more consistent with the uncertainty relationship of human interference between independent and dependent variables in practice with profit return function as a potential function. Rewards for underwriters can be judged according to the principle of experience, which copes with actual situations more properly. (2) Differences of satisfaction exist between underwriters and issuing companies for IPO pricing in the underwriting system. Profit or satisfaction exchange can be conducted appropriately during the process of negotiating offering prices. (3) The comparison of profit changes and satisfaction sensitivity between underwriters and issuing companies can be served as a reference of exchange and increase in satisfaction for underwriters and issuing companies
