Information Technology Commodity Trading, Non-symmetrical Conditions

Because of information asymmetry existing prevalently in the transaction of technology merchandise, the players may take their own information advantages to serve for their own benefits, which do harm to the technology transaction. So, in order to increase the efficiency of transaction and make the technology market develop healthily and orderly, it is necessary to reduce the negative effect on technology merchandise transaction, which caused by information asymmetry.This paper firstly defines the information asymmetry of technology merchandise transaction, and analyses the distribution of the information among the buyer, the seller and the media. By means of the game theory, the paper represents the situations that the technology merchandise is transacted by the buyer and the seller directly, and the situation that the merchandise is transacted by the buyer, the seller and the media, analyses the behavior of the players respectively, and the negative effect on technology transaction caused by those behavior. Then the paper designs the general incentive mechanism responding to the two transaction situations mentioned above by the principal-agent theory of information economics. That is, in condition of satisfying the individual rationality constraint of every player, carrying out the incentive mechanism through reasonable supervision and proper punishment, to restrain the hazard behaviors caused by the players' taking their advantages of information asymmetry. the low efficiency of the technology merchandise transaction is partly caused by difficulties in technology merchandise pricing. So, the paper uses the joint-cardinal number method of principal-agent theory, give a joint-cardinal number pricing method of technology merchandise. What more, according to the analysis of game behavior and the study of incentive mechanism, the paper gives some constructive suggestions respectively around technology merchandise transaction.
