"Digital goods have created large gains in well-being that are missed by conventional measures of GDP and productivity"
A new paper by ERIK BRYNJOLFSSON et al. suggests using massive online choice experiments as a method to find the true impact of digital goods on well-being. The background section gives an example of the impact that is currently unmeasured:
“... [in] a number of sectors ... physical goods and services are being substituted with digital goods and services. An apropos example of such a transition good is an encyclopedia. Since the 2000s, people have increasingly flocked to Wikipedia to get information about a wide variety of topics updated in real time by volunteers. In 2012, Encyclopedia Britannica, which had been one of the most popular encyclopedias, ceased printing books after 244 years (Pepitone 2012). Wikipedia has over 60 times as many articles as Britannica had, and its accuracy has been found to be on par with Britannica (Giles 2005). Far more people use Wikipedia than ever used Britannica—demand and well-being have presumably increased substantially. But while the revenues from Britannica sales were counted in GDP statistics, Wikipedia has virtually no revenues and therefore doesn’t contribute anything to GDP other than a few minimal costs for running servers and related activities and some voluntary contributions to cover these costs…For such transition goods, consumer surplus increases as free access spurs demand, but revenue decreases as prices become zero. Hence GDP and consumer welfare actually move in opposite directions.”
One finding of note: “50% of the Facebook users in our sample would give up all access to Facebook for one month if we paid them about $50 or more.” Link to paper on NBER here popup: yes. A free draft is available here popup: yes.
