This paper develops a framework for measuring digital services in the face of ongoing innovations in the delivery of content to consumers. We capture what Brynjolfsson and Saunders (2009) call "free goods" as the capital services generated by connected consumers' stocks of IT digital goods, a...

Digitalization led to a rapid expansion of loyalty tokens typically bundled as part of product price. An open question is whether issuers are incentivized to make loyalty tokens tradable, raising regulation issues for monetary and banking authorities. This paper argues that an issuer earns more...

Firms spend substantial resources on marketing and selling. Interpreting this as evidence of frictions in product markets, which require firms to spend resources on customer acquisition, this paper develops a search theoretic model of firm dynamics in frictional product markets. Introducing...

This paper demonstrates that it is possible to construct accurate pictures of firm revenue, growth, geographic dispersion, and customer base characteristics using an increasingly accessible class of consumer financial transaction data. We develop two new measures which characterize firms'...

How do peers influence the impact of incentives? Despite much work on incentives, little is known about the spillover effects of incentives. We investigate two mechanisms by which these effects can occur: through peers' actions and peers' incentives. In a field experiment on snack choice (grapes...

Using box-office data for all movies released between 1982 and 2000, I test the implications of a simple model of social learning in which the consumption decisions of individuals depend on information they receive from their peers. The model predicts different box office sales dynamics...

Social interactions are widely understood to influence consumer decisions in many choice settings. This paper identifies causal peer effects in water conservation during the growing season, utilizing variation from consumer migration. We use machine learning to classify high-resolution remote...

Academic Medical Centers (AMCs)--comprising medical schools, teaching hospitals, and research laboratories)--play an important role in US biomedical innovation. The Balanced Budget Act of 1997 (BBA) changed the formula used to reimburse Medicare inpatient claims and subsidies for medical...

We study the nature of peer effects in the market for new cell phones. Our analysis builds on de-identified data from Facebook that combine information on social networks with information on users' cell phone models. To identify peer effects, we use variation in friends' new phone acquisitions...
