It is now widely recognized that regulatory failures contributed to the onset of the global financial crisis. Redressing such failures has, thus, been a key policy priority in the post-crisis reform agenda at both the domestic and international levels. This special issue investigates the process of post-crisis financial regulatory reform in a number of crucial issue areas, including the rules and arrangements that govern financial supervision, offshore financial centers and shadow banking, the financial industry's involvement in global regulatory processes, and macroeconomic modeling. In so doing, the main purpose of this special issue is to shed light on an often understudied aspect in regulation literature: the variation in the dynamics of regulatory change. Contributors examine the different dynamics of regulatory change observed post-crisis and explain variations by accounting for the interaction between institutional factors, on the one hand, and the activity of change agents and veto players involved in the regulatory reform process, on the other.
