Sometimes, it is possible for an industry to preempt government regulation by mitigating the societal concerns that prompt the government to intervene. This is desirable when government intervention is likely to be clumsy. Executing preemption is difficult. The challenge lies in the absence of enforcement power: not every industry player, and sometimes no single industry player, necessarily has an incentive to do what is desirable for the industry as a whole. And, by construction, there is no Institution with the power to impose change. This chapter studies two general settings in which this challenge exists and, nevertheless, the industry is able to achieve optimal preemption.
