Over the past forty years, numerous theoretical advances have been made. From Ayres’ and Braithwaite’s ground breaking work on 'responsive regulation', we have seen models of ‘smart regulation’, 'regulatory governance' and 'regulatory capitalism' emerge to capture the growing prevalence and importance of regulation in modern liberal Western capitalist societies. Important advances also have been made in the practice of regulation, with regulators evolving from traditional enforcement focussed ‘command and control’ models to being ‘modern regulators’ with a suite of diverse and innovative regulatory tools at their disposal. --
