Minah Jung volunteered at Karma Kitchen and became  interested in further investigating the pay-forward approach in a research setting.  She ends up joining Professor Leif Nelson at UC Berkeley's Haas Business School whose past research has shown that shared social responsibility (ie. pay-what-you-want with percentage donated to charity) is far more effective than corporate social responsibility.  Minah and Leif started researching pay-forward transactions in interesting ways.  In a recent experiments, they showed that $1 admission at a museum received $1.23 when it was pay-what-you-want in a box, $2 when it was pay-what-you-want to a person and $3 when it was pay-forward for the person after you.  Quite fascinating.  Today, all of us had an elevated meeting, after which Leif wrote, "We had high expectations for our meeting today. You exceeded all of them. I think that there is a lot that we can do together to advance our knowledge about this domain and to advance the amazing work that ServiceSpace has done."  Stay tuned for more. :)
