Abstract:

To protect the fairness of trade pricing of water discharging rights and to promote effective execution of water discharging right trade, this paper establishes an asymmetric information barging model based on fairness-preferred trade pricing of water discharging rights, which adopts reverse induction to solve three-staged barging gambling balance. Matlab R2014a is used to analyze the impacts of parameters on premier pricing and gambling effect. The higher acceptable lowest compensation price by seller is or highest compensation price by buyer is, the higher premier price is. If the highest compensation price by seller equals to the lowest acceptable compensation price by buyer in increment, the increased asking premier price by the former is larger than the latter. Fairness preference and discounting factor have little direction impacts on premier pricing at different gambling stages. The lower the lowest compensation price accepted by seller is or the higher the highest compensation price paid by buyer is, meaning a larger barging range, the higher the gambling effect will be made by both sides. The larger the barging discounting factor by both is, the larger gambling effect will be acquired by both. As discounting factor rises, if fairness preference maintained at a certain level, the buyer's whole gambling effect level is lower that the seller even if buyer asks price first and both maintain an equal earning increment.

Key words: water discharging trade pricing, barging, fairness preference, asymmetric information
