 Doctrinal analysts within economic analysis of law face a somewhat lesser difficulty. Their project simply asks whether a legal rule that rationalizes a pattern of outcomes induces efficient behavior (perhaps within some model). One can pursue this task rule-by-rule and independently of the jurisdiction. The general claim then states simply that the doctrine in most jurisdictions is by-and-large rationalized by rules that induce efficient behavior. As more than one rule governing the same conduct may induce efficient behavior, there is no implication that rules are identical in different  jurisdictions.[12]
