The Rise of the Regulatory State

During the Progressive Era at the beginning of the 20th century, the United States replaced litigation by regulation as the principal mechanism of social control of business. To explain why this happened, we present a model of choice of law enforcement strategy between litigation and regulation based on the idea that justice can be subverted with sufficient expenditure of resources. The model suggests that courts are more vulnerable to subversion than regulators, especially in an environment of significant inequality of wealth and political power. The switch to regulation can then be seen as an efficient response to the subversion of justice by robber barons during the Gilded Age. The model makes sense of the progressive reform agenda, and of the successes and failures of alternative law enforcement strategies in different countries
