I study the impact of consumer reviews on the incentives for firms to participate in the market. Firms produce goods of heterogeneous, unknown quality that is gradually revealed via consumer reviews, and face both entry and exit decisions. A platform combines past reviews to construct...

We analyze the linking and versioning strategies of a media firm when facing competition from blogs, search engines and news aggregators. First, we show that when the publisher competes against a blog it is less likely to release a fighting version if this generates signi ficant spillovers for...

Many scholars argue that content providers, when incentivized by ad revenue, are more likely to tailor their content to attract “eyeballs,” and as a result, popular content may be excessively supplied. We empirically test this prediction by taking advantage of the launch of an...

Increasingly detailed consumer information makes sophisticated price discrimination possible. At fine levels of aggregation, demand may not obey standard regularity conditions. We propose a new randomized sales mechanism for such environments. Bidders can "buy-it-now" at a posted price, or...

Many video ads are designed to go 'viral,' so that the total number of views they receive depends on customers sharing the ads with their friends. This paper explores the relationship between number of views and how persuasive the ad is at convincing consumers to purchase or to adopt a favorable...

This paper studies the impact of platform-owner entry threat on complementors in platform-based markets. We examine how app developers on the Android mobile platform adjust innovation efforts (rate and direction) and value-capture strategies in response to the threat of Google's entry into their...

We study how the sharing of peer success on an enterprise digital platform affects worker productivity. Using sales workers in an information technology service company as our research context, we leverage the unexpected resignation of several human resources staff as an exogenous shock to the...

Online rating systems can lead, on occasion, to reviews that are unfair or un-representative of the true quality provided. On the one hand, receiving an unfairly low rating once, might induce someone a platform supplier to exert more effort and receive a better rating the next time. On the other...

This paper examines price data on over 222 LCD televisions to estimate indirect network effects arising from two sources. First, we conjecture that the disconnect between the timing of when broadcasters are required to convert to an only-digital-signal world and when television manufacturers are...

The concept of a 'global digital divide' is now common, and many cross-country studies of determinants of differences in computer and Internet penetration have been performed. The main conclusions and policy implications from these studies are relatively blunt: get richer, have more telephones,...
