| Why do economists conduct experiments? To answer that question, it is first necessary briefly to specify the ingredients of an experiment. Every laboratory experiment is defined by an environment, specifying the initial endowments, preferences and costs that motivate exchange. This environment is controlled using monetary rewards to induce the desired specific value/cost configuration (Smith, 1991, 6). 1 An experiment also uses an institution defining the language (messages) of market communication (bids, offers, acceptances), the rules that govern the exchange of information, and the rules under which messages become binding contracts. This institution is defined by the experimental instructions which describe the messages and procedures of the market, which are most often computer controlled. Finally, there is the observed behavior of the participants in the experiments as a function of the environment and institution that constitute the controlled variables. Using this framework of environment, institution, and behavior, I can think of at least seven prominent reasons in the literature as to why economists conduct experiments. Undoubtedly, there are more (Davis and Holt, 1992, chapter 1 and passim). | |||||||||||||||
