 The methodology of economic analysis of law poses a more significant challenge to traditional accounts of law. Economic analysis of law provokes disquiet because the model of self-interested maximization of preferences apparently does not admit a concept of normativity but explaining the normativity of law is a central pre-occupation of philosophy of law. The logic of this commitment to self-interested maximization of preferences would appear to lead to a denial of the need for a distinct concept of law in the explanation and evaluation of social institutions. As section 4 suggested, this denial of normativity may only be apparent as the methodological resources of economic analysis of law allow for at least some accommodation for the incorporation of some normative reasons into the explanation of behavior.
