Experimental Economics: Comment
评论了Charles Plott和Vernon Smith关于实验室实验在经济学中应用的研究，指出实验依赖于诱导被试按预设价值结构反应，并讨论了这一关键特征在标准经济理论中的核心作用。
In two important studies, Charles Plott (1982) and Vernon Smith (1982) assess the current state of the literature about laboratory experiments in economics. As a profession, we are becoming aware that experimental methods can be applied to our models, with cautious but growing confidence that these procedures can help us evaluate alternative theories. These are significant developments whose potential ramifications are only beginning to be explored. Given the importance of laboratory testing, I would like to discuss a key feature of past experiments, one that has not been fully appreciated because of its central role in standard economic theory. In particular, these experiments depend on inducing agents to respond according to a prespecified value structure. This usually amounts to starting with a known and fully determinate set of demand and supply value schedules for all transacting agents. Smith, for example, specifies four major principles about how preferences are to be experimentally induced (nonsatiation, saliency, dominance, and privacy; see pp. 931-35).
