I know this is economic jargon, but essentially, if you bring more women to the job market, you create value, it makes economic sense, and growth is improved. There are countries where it's almost a no-brainer: Korea, Japan, soon to be China, certainly Germany, Italy. Why? Because they have an aging population.

Gender-dominated environments are not good... particularly in the financial sector where there are too few women. In gender-dominated environments, men have a tendency to... show how hairy chested they are, compared with the man who's sitting next to them. I honestly think that there should never be too much testosterone in one room.

I hate to say there are female and male ways of dealing with power, because I think each of us has a male and a female part. But based on my own experience, women will tend to be inclusive, to reach out more, to care a little more.

To me, leadership is about encouraging people. It's about stimulating them. It's about enabling them to achieve what they can achieve - and to do that with a purpose.
