Wellesley College Leadership (economics)

Hello,
Wellesley says that it fosters in women strong real-life leadership. I know that they do by looking at its alumni network, but I’m not quite sure how they foster leadership in students. Are there special programs that are specifically directed to leadership or is it just the Wellesley’s social and academic experience?
I’m interested in economics, business and international affairs. It’d be great if I could get some information specifically to this field. A general one is fine too

Thanks!

This was mentioned several times on the tour as a fantastic experience. http://web.wellesley.edu/Albright/index2.html
