Social networking's hidden ethical value
Endless ink, digital and otherwise, has been spent debating whether Facebook, Twitter, and the rest of the rapidly-multiplying social media ilk are the best or worst thing ever to happen to humankind. Much less has been spent on what it means for markets.
But a recent story about car-pooling apps highlights the fact that modern technology, including social media, has a role to play in making markets more efficient. And since efficient markets are generally a good thing, this counts as a big checkmark in the "plus" column of our calculations concerning the net benefit of social media.
Another big enemy of efficient markets is monopoly power, essentially a situation in which some market actor enjoys a relative lack of competition and hence has the ability to throw its weight around. Social media promises improvements here, too. Sites like Groupon allow individuals to aggregate in ways that give them substantial bargaining power.
The general lesson here is that markets thrive on information. Indeed, economists' formal models for efficient markets assume that all participants have full knowledge-that is, they assume that lack of information will never be an issue. Social networks are providing increasingly sophisticated mechanisms for aggregating, sharing, and filtering information, including important information about what consumers want, about what companies have to offer, and so on. So while a lot of attention has been paid to the sense in which social media are "bringing us together," the real payoff may lie in the way social media render markets more efficient.
