Abstract: | In light of the shill bidding fraud by the seller in online auctions, this paper builds a supervi- sion game model for the shill bidding on the basis of non-cooperation game theory and method with the cost factors considered. It analyzes the possible strategies and the mixed Nash equilibrium when the supervision department and sellers are interdependent. With the research into the strategies by the regulatory authorities and the sellers, it has obtained the optimal penalty factor analytic formula that can be used as a guidance by the regulatory authorities in their punishment of the sellers who have cheated by shill bidding. |
