This part of this website looks at a number of important and/or controversial questions faced by those responsible for designing regulatory systems:
Regulating Large Organisations - or Why Some Big Companies Behave Badly
The Behaviour of Regulatory Organisations - and their weaknesses
In particular - Are some regulators too big to be effective?
- Openness and Transparency
You might also find it helpful to read the key questions that need to be asked by the Boards of regulatory organisations when carrying out Effectiveness Reviews.
Finally, I offer some international comparisons here.
