Standard economic measures don’t account for digital gems:
You may think that Wikipedia, Twitter, Snapchat, Google Maps, and so on are valuable. But, as far as G.D.P. is concerned, they barely exist. The M.I.T. economist Erik Brynjolfsson points out that, according to government statistics, the “information sector” of the economy—which includes publishing, software, data services, and telecom—has barely grown since the late eighties, even though we’ve seen an explosion in the amount of information and data that individuals and businesses consume. “That just feels totally wrong,” he told me.
Brynjolfsson is the co-author, with Andrew McAfee, of the forthcoming book “The Second Machine Age,” which examines how digitization is remaking the economy. “We’re underestimating the value of the part of the economy that’s free,” he said. “As digital goods make up a bigger share of economic activity, that means we’re likely getting a distorted picture of the economy as a whole.” The issue is that, as Kuznets himself acknowledged, “the welfare of a nation . . . can scarcely be inferred from a measure of national income.” For instance, most Web sites are built with free, open-source applications. This makes running a site cheap, which has all sorts of benefits in terms of welfare, but G.D.P. ends up lower than it would be if everyone had to pay for Microsoft’s server software. Digital innovation can even shrink G.D.P.: Skype has reduced the amount of money that people spend on international calls, and free smartphone apps are replacing stand-alone devices that once generated billions in sales. The G.P.S. company Garmin was once one of the fastest-growing companies in the U.S. Thanks to Google and Apple Maps, Garmin’s sales have taken a severe hit, but consumers, who now have access to good directions at no cost, are certainly better off.
