The problem is that GDP measures the total amount spent on these goods and services. If the price is zero, then “zero times any quantity is still zero. So you could have an enormous of explosion of bits or articles or whatever else. If they’re priced at zero, the statisticians in Washington do the math and, lo and behold, it comes out as a big fat zero contribution for our GDP.” Traditional metrics have not been adequate for the information economy because so much of the digital economy has been free."
