EDIT 1: Apologies @pikzen. Edited to agree with you :). I should read more carefully on a Friday morning. EDIT 2: And you :).
I agree, there are plenty of examples where regulation works. The National Health Service in the UK is a shining example of this (it has its own issues but what can you expect when you are running one of the largest organisations in the world?). There are succesful regulations that reward companies (such as with subsidies and other indirect incentives) to choose the 'morally correct' option (this is done for example in the EU to limit environmental impact of industry).
