Saying that MBAs are increasingly attracted to the social sector, which in contrast to for-profit businesses it defines as organizations committed to creating social value rather than personal or shareholder wealth, Harvard Business Review's Working Knowledge series says that more entrepreneurial methods can help these organizations achieve their goals. And those entrepreneurial methods should focus on networks of all kinds.
The HBS summary linked above says that the non-profit and social sector has assets valued at over $2 trillion. I'm sure that the "social sector" in the study has been defined pretty broadly, and I'm equally sure someone will tell me that those $2 trillion in assets don't translate directly into capital assets, but I wonder if that sector will ever have a higher capitalization than profit-only enterprises. That would be new, wouldn't it?
