The Laboratory as a Discovery Process? Vernon Smith, Hayek, and Experimental Economics

Ian Irwin, Andrew Yuengert


In Rationality in Economics, Vernon Smith argues that experimental methods establish the ecological rationality of markets, thus confirming Friedrich Hayeks assertion that market competition fosters emergent norms and institutions that are preferable to constructivist order. In making this argument, Smith must contend with Hayeks brief dismissal of the value of experimental market demonstrations. Hayeks doubts can be explained by his skepticism of the concept of economic efficiency. In experiments, ecological rationality is operationalized as efficiency, but Hayek rejects efficiency for two reasons. First, even though experiments do not fully specify institutions and equilibrium concepts, their specification of the commodity space, preferences, and technologies obscure the function of competition, which is to elicit this information. Second, Hayek argues that preferences evolve, rendering efficiency-based normative arguments for markets problematic. Consistent with this evolutionary framework, Hayeks arguments for competitive order do not invoke efficiency. Instead, he argues that markets promote human initiative and that widespread human suffering will result from the abandonment of competitive order in those countries that rely on it.
