|February 2019||Assessing the Gains from E-Commerce|
with Paul Dolfen, Liran Einav, Peter J. Klenow, Jonathan D. Levin, Laurence Levin, Wayne Best: w25610
E-Commerce represents a rapidly growing share of consumer spending in the U.S. We use transactions-level data on credit and debit cards from Visa, Inc. between 2007 and 2017 to quantify the resulting consumer surplus. We estimate that E-Commerce spending reached 8% of consumption by 2017, yielding consumers the equivalent of a 1% permanent boost to their consumption, or over $1,000 per household. While some of the gains arose from saving travel costs of buying from local merchants, most of the gains stemmed from substituting to online merchants. Higher income cardholders gained more, as did consumers in more densely populated counties.
