This is Scientific American Sixty seconds science. I'm Christopher.  Facebook is currently worth some 400 bn dollars to its shareholders, which might seems like a lot, but recent studies suggests the company is worth many times more than that to its users. ??a punchline that facebook does seem to bring value to its users and maybe that's a nice thing anybody said about ZB earlier, you know but it does seem to bring joy and utility to people. Shanbe Cash is an economist at tough's University in Boston.  He and his team asked some 1300 facebook users from colleges community and online samples to put a  dollar figure,  on the value the social media brings to their lives, specifically they ask users how much they need to be paid to deactivate their accounts and the stakes were real if the user's offer was accepted she'd have to deactivate account for up to a year and Cash, remember that's the actual one name of the economist Cash would have to pony up the money. We did have some budget breaking surprises but just have bigger of  surprise? Cash is seemed found that on average users ask for more than 1000 dollars in exchange for shutting down their accounts for a year. He reported the result in the Journal plus one. If you divide facebook's market capitalization by its number of users more than  2.2bn, you'd find that each user's worth about 175 bucks to investors, but actual users seem to prize access  to the platform at more that five times that, not the Cash and his team suggesting CEO MZ should actually charge that much for access, but what their measuring  instead is what's called consumer surplus or more simply put the additional perceived value the users get from using the service.  If you think about the history of innovation in general, it's often the case even when we see somebody like Edison making a lot of money out of the light bulb,  the value ?the users of light bulb, since then has been much higher than whatever fortune he made. Facebook's never-ending string of privacy misstep so might affect whether we'll see the same of the social network in the future, whether ZB likes it or not.
