In this paper, we propose a new observable criterion called Marshallian deviation. It can be used to measure the distance of a transaction path deviating from the Marshallian path mathematically, and to answer the question why buyers with high values will trade with sellers with low costs in advance in some types of DA but not in others. Furthermore, three factors influencing the Marshallian deviations both in the CDA and in the PDA are also studied. They are respectively the strategic algorithm, the transaction duration and the number of traders. A few interesting findings are presented.展开更多
