Internet Security, Vulnerability Disclosure and Software Provision* In this paper, we examine how software vulnerabilities affect firms that license software and consumers that purchase software. In particular, we model three decisions of the firm: (i) an upfront investment in the quality of the software to reduce potential vulnerabilities; (ii) a policy decision whether to announce vulnerabili...
Dual licensing has proved to be a sustainable business model for various commercial software vendors employing open source strategies. In this paper we study the main characteristics of dual licensing and under which conditions it represents a profitable commercial strategy. We show that dual licensing is a form of versioning, whereby the software vendor uses the open source licensing terms in ...
We discuss economic rationales behind peering decisions in the Internet. In the first part of the paper we analyze the decision about a bilateral peering agreement between two commercial Internet service providers (ISPs) who are in Cournot competition. In the second part we discuss multilateral peering between commercial ISPs and an academic research network (ARN). The latter is organized as cl...
We consider market rules for transferring IP addresses, numeric identifiers required by all computers connected to the Internet. Transfers usefully move resources from lowest to highest-valuation networks, but transfers tend to cause socially costly growth in the Internet’s routing table. We propose a market rule that avoids excessive trading and comes close to achieving social efficiency. We a...
M P Ra Understanding the Internet's Relevance to Media Ownership Policy: a Model of Too Many Choices
Does the Internet provide a failsafe against media consolidation in the wake of an easing of media ownership rules? This paper posits a model of news outlet selection on the Internet in which consumers experience cognitive costs that increase with the number of options faced. Consistent with psychological evidence, these costs may be reduced by constraining one’s choice set to “safe bets” famil...
Scholars have argued that online social networks and personalized web search increase ideological segregation. We investigate the impact of these potentially polarizing channels on news consumption by examining web browsing histories for 50,000 U.S.-located users who regularly read online news. We find that individuals indeed exhibit substantially higher segregation when reading articles shared...
We estimate the sensitivity of Internet retail purchasing to sales taxes using eBay data. Our first approach exploits the fact that a seller’s location—and therefore the applicable tax rate—is revealed only after a buyer has expressed interest in an item. We document how adverse tax “surprises” reduce the likelihood of purchase and shift subsequent purchases toward out-of-state sellers. We then...
This paper offers an analysis of the evolution of e-commerce markets. We develop a model in which an initial group of small, no-name “click” firms create such markets by offering horizontally differentiated customized or “versioned” products and competing in prices. Subsequently, a traditional “brick” firm enters by stretching its brand name into the digital marketplace. Such entry causes many ...
We show that social interaction reduces the diversity of products purchased by consumers in two retail settings. First, we consider a field experiment conducted by Sweden’s monopoly alcohol retailer and find that moving purchases from behind the counter to self-service disproportionately increases the sales of difficult-to-pronounce products. Second, we use individual-level panel data from a pi...
Pricing schemes that vary prices in response to demand shocks may antagonize consumers and reduce demand. At the same time, consumers may take advantage of the opportunities offered by price changes. Overall, the net impact of varying price on demand is ambiguous. We investigate the issue empirically, exploiting a unique dataset from a firm that has experimented with different pricing schemes. ...
