Controlling Contradictions Among Regulations
研究发现国会一次只处理一种外部性，导致立法和监管机构只针对单一问题制定标准，很少考虑与其他联邦法规的矛盾。
Congress pursues externalities one at a time. The resulting legislation embodies the same sequential approach, instructing regulatory agencies to set and enforce standards for a single problem. Rarely, if ever, are agencies instructed or even permitted to account for contradictions with other federal legislation and rulemaking.
