As legal concepts have evolved over recent decades, statistical techniques have come to play an increasingly important role in providing evidence for litigation. One of the greatest values that legal models provide is in helping to guide firms’ decisions with respect to legal complaints before a trial ever occurs; cost-benefit analysis can facilitate the process of settlements or contract conditions that can help companies to make better forward-looking decisions. As efficiency-based solutions have become a core part of corporate legal practice, risk modeling has emerged as a prominent cost-saving technique. Some of the key contributions to concepts of efficiency in law and economics include:
The Coase Theorem
Formulated by economist Ronald Coase, the Theorem poses an efficient solution of property rights in the context of externalities. At a basic level, the solution states that costs can be incorporated into decisions between private parties in the absence of regulation or government regulation. The original problem came about when Coase analyzed property rights in the context of radio frequency interference – while the FCC sought a solution by seeking to change the structure of the FM and AM allocations, Coase proposed in his paper “The Problem of Social Cost” that stations should be allowed to freely buy and sell frequency levels, allowing them to buy up blocks of frequencies close to theirs to eliminate complications. This solution has been, in turn, applied to a variety of legal problems related to externalities, especially in environmental law, and led to Coase being awarded the Nobel Prize for Economics. In practice, the Theorem has greatly influenced tort law, when Judge Hand began applying cost-benefit analysis to property dispute cases. Many scholars have argued that transactions costs and regulations are too costly to allow the private system to work, especially in cases of indirect pollution and unseen costs.
Kaldor Hicks Efficiency
A central concept in economic efficiency related to Pareto efficiency conditions, Kaldor-Hicks seeks to identify conditions in which utility of various parties might be improved through alternate allocation. In a standard sense, allocations are considered Pareto-efficient where the utility of at least one party is improved, while no others are harmed – on the other hand, Kaldor-Hicks allows for the “winning” parties to monetarily compensate the losers in order to clear a transaction. The theory has wide-ranging implications for property and environmental law, in addition to contribution broad solutions to management problems involving conflicting party interests.
