The regulation of economic life, whether through law or politics, has been a fixture of daily life from time immemorial. Formal regulation occurs through a variety of formal devices, the efficacy of which is argued about by legal scholars, economists, policymakers, legislators, and governments. Even expressions like “to regulate” or “to deregulate” carry a range of political and even moral connotations, depending on who is using the phrase and how they are deploying it.
