Valuing New Goods in a Model with Complementarities: Online Newspapers

Matthew Gentzkow

No 12562, NBER Working Papers from National Bureau of Economic Research, Inc

Abstract: Many important economic questions hinge on the extent to which new goods either crowd out or complement consumption of existing products. Recent methods for studying new goods are based on demand models that rule out complementarity by assumption, so their applicability to these questions has been limited. I develop a new model that relaxes this restriction, and use it to study the specific case of competition between print and online newspapers. Using new micro data from the Washington DC market, I show that the major print and online papers appear to be strong complements in the raw data, but that this is an artifact of unobserved consumer heterogeneity. I estimate that the online paper reduced print readership by 27,000 per day, at a cost of $5.5 million per year in lost print profits. I find that online news has provided substantial welfare benefits to consumers and that charging positive online prices is unlikely to substantially increase firm profits.
