Firms' incentives to manufacture biased user reviews impede review usefulness. We examine the differences in reviews for a given hotel between two sites: Expedia.com (only a customer can post a review) and TripAdvisor.com (anyone can post). We argue that the net gains from promotional reviewing...

This paper analyzes the implications of the inherent conflict between two tasks performed by direct marketing agents: prospecting for customers and advising on the product's "suitability" for the specific needs of customers. When structuring salesforce compensation, firms trade off the expected...

We compare house sales on a For-Sale-By-Owner (FSBO) platform to Multiple Listing Service (MLS) sales and find that FSBO precommission prices are no lower, but that FSBO is less effective in terms of time to sell and probability of a sale. We do not find direct evidence of the importance of...

Popular accounts suggest that advertising revenue per unit of consumer attention is lower online than offline, and has fallen in traditional media as the Internet has made advertising markets more competitive. I assess these claims theoretically and empirically, and compare the patterns we...

We document some early effects of how mobile devices might change Internet and retail commerce. We present three main findings based on an analysis of eBay's mobile shopping application and core Internet platform. First, early adopters of mobile e-commerce applications appear to be people who...

Context can influence decisions. This malleability of choice is usually invoked as evidence that people do not maximize stable preference orderings. In a market equilibrium, however, context conveys payoff-relevant information to consumers. Consequently, these consumers rationally violate naïve...

The author develops a model in which a firm's only asset is its name, which summarizes its reputation, and studies the forces that cause names to be valuable, tradable assets. An adverse selection model in which shifts of ownership are not observable guarantees an active market for names with...

We document three remarkable features of the Opower program, in which social comparison-based home energy reports are repeatedly mailed to more than six million households nationwide. First, initial reports cause high-frequency "action and backsliding," but these cycles attenuate over time....

We survey 561 students from U.S. medical schools shortly after they submit choice rankings over residencies to the National Resident Matching Program. We elicit (a) these choice rankings, (b) anticipated subjective well-being (SWB) rankings, and (c) expected features of the residencies (such as...

Revealed preference theory assumes that each consumer has demands that are rational, meaning that they arise from the maximization of his or her own utility function. In contrast, econometric or statistical demand models assume that each consumer's demands equal a rational systematic component...
