Cost-benefit analysis is analyzed using a model of agency delegation. In this model an agency observes the state of the world and issues a regulation, which the president may approve or reject. Cost-benefit analysis enables the president to observe the state of the world (in one version of the model), or is a signal that an agency may issue (in another version). The roles of the courts, Congress, and interest groups are also considered. It is argued that the introduction of cost-benefit analysis increases the amount of regulation, including the amount of regulation that fails cost-benefit analysis; that the president has no incentive to compel agencies to issue cost-benefit analysis, because agencies will do so when it is in the president’s interest, and otherwise will not do so; that presidents benefit from cost-benefit analysis even when they do not seek efficient policies; that agencies and their supporters ought to endorse cost-benefit analysis, not resist it; and that cost-benefit analysis reduces the influence of interest groups. Evidence for these claims is discussed. Finally, it is argued that courts should force agencies to conduct cost-benefit analyses in ordinary conditions, but that they should not force agencies to comply with them.
