Abstract
AbstractFour topics related to the operation of regulatory systems are considered. These concern the matters of dealing with globally sub‐optimal decisions made by regulators, the problem of specifying boundaries between groups of regulated entities in the application of regulation, dealing with a situation in which there are multiple regulators, and the alignment of regulation across jurisdictional borders. It is argued that current responses to these dilemmas tend to add to levels of inefficiency in the economy, with consequences for growth. Options for resolving them are considered, including new approaches to the design of regulation.
