I'll put her on <a href="http://bit.ly/2YdETwH" rel="nofollow">levitra</a>  Not long ago, Diane Mulcahy, who manages the private-equity portfolio at the Ewing Marion Kauffman Foundation, led a quantitative study of venture capital over the past two decades, showing that recently the average V.C. fund has barely broken even. Venture funds were growing, yet most venture capitalists didn&#8217;t have skin in the game: only one per cent of the money in a V.C. firm&#8217;s kitty might come from its partners. Mulcahy discovered that it was a bad deal for investors. Her foundation scaled back its V.C. investments, and so did a lot of others.
