ABSTRACT
According to Gode and Sunder (1993), the invisible hand even exists in a market composed of non-purposive agents (individual irrationality). However, our Homo sapiens are definitely purposive. When placed in a well-defined experiment like the DA market, Homo sapiens are naturally attracted by transaction gains, and it is not likely that blind bidding and asking will be a sensible way for them to react upon the information they acquired.1
