There was a study done in the UK a few years ago (London Business School) that showed that students who chose to do an MBA were less ethical than other students. This worried the Business School deans because they did not know if the less ethical students chose to do an MBA, or if something in the curriculum made them less ethical.
A new study has come out by the Durham Business School and the Association of MBAs: "The Post Downturn MBA: An Agenda For Change", which claims that business school students and graduates are now much keener on busienss ethics and sustainability and they give interesting statistics. Toby Webb gives a very interesting review of this research in his blog on Ethical Corporation.
A lot of indicators are pointing in the right direction, so there might be hope for the economy and the world after all. Not to mention the survival of capitalism.
