Big Data and the Attention Economy
While attention has always been prized above money, few people have had the means to attract it to themselves. But the new digital economy has provided everyone with a loudspeaker; thus efforts at getting noticed have rapidly escalated in global society. The attention economy focuses on the mechanisms that mediate the allocation of this scarce entity. Social networks and big data play a role in determining what is noticed and acted upon
Securing private data sharing in multi-party analytics
A general class of problems arises when datasets containing private information belong to multiple parties or owners and they collectively want to perform analytic studies on the entire set while respecting the privacy and security concerns of each individual party. We describe a solution to this problem in the form of a secure procedure for data mapping and/or linkage, which allows to identify the correspondence between entities in a distributed…
Trend Dynamics and Attention in Chinese Social Media
We analyzed the temporal aspect of trends and trend-setters in Sina Weibo, contrasting it with earlier observations of Twitter. We found a vast difference in the content shared in China as compared with a global social network such as Twitter. In China, the trends are created almost entirely due to the retweets of media content such as jokes, images, and videos, unlike Twitter where trends have more to do with current global events and news stori…
To Switch or Not To Switch
The authors designed and ran an experiment to measure social influence in online recommender systems, specifically, how often people's choices are changed by others' recommendations when facing different levels of confirmation and conformity pressures. In this experiment, participants were first asked to provide their preference from pairs of items. They were then asked to make second choices about the same pairs with knowledge of other people's …
A market for unbiased private data
Since there is, in principle, no reason why third parties should not pay individuals for the use of their data, we introduce a realistic market that would allow these payments to be made while taking into account the privacy attitude of the participants. And since it is usually important to use unbiased samples to obtain credible statistical results, we examine the properties that such a market should have and suggest a mechanism that compensates…

Predicting the Future with Social Media
In recent years, social media has become ubiquitous and important for social networking and content sharing.And yet, the content that is generated from these websites remains largely untapped.In this paper, we demonstrate how social media content can be used to predict real-world outcomes.In particular, we use the chatter from Twitter.com to forecast box-office revenues for movies.We show that a simple model built from the rate at which tweets ar…
Influence and Passivity in Social Media
A persistence paradox
It is widely believed that persistence in most endeavors is essential to their success. By its very nature, persistence enhances both the quality of an outcome and its probability of success because people are willing to endure failures before achieving a desired goal. To test this hypothesis on a massive scale, we studied the production histories and success dynamics of 10 million videos uploaded to a popular video Web site. Our results reveal t…
Social networks that matter
Scholars, advertisers and political activists see massive online social networks as a representation of social interactions that can be used to study the propagation of ideas, social bond dynamics and viral marketing, among others. But the linked structures of social networks do not reveal actual interactions among people. Scarcity of attention and the daily rythms of life and work makes people default to interacting with those few that matter an…
The dynamics of viral marketing
We present an analysis of a person-to-person recommendation network, consisting of 4 million people who made 16 million recommendations on half a million products. We observe the propagation of recommendations and the cascade sizes, which we explain by a simple stochastic model. We analyze how user behavior varies within user communities defined by a recommendation network. Product purchases follow a ‘long tail’ where a significant share of purch…
Assessing the value of cooperation in Wikipedia
Since its inception six years ago, the online encyclopedia Wikipedia has accumulated 6.40 million articles and 250 million edits, contributed in a predominantly undirected and haphazard fashion by 5.77 million unvetted volunteers. Despite the apparent lack of order, the 50 million edits by 4.8 million contributors to the 1.5 million articles in the English–language Wikipedia follow strong certain overall regularities. We show that the accretion o…
E-Mail as Spectroscopy
We describe a method for the automatic identification of communities of practice from e-mail logs within an organization. We use a betweenness centrality algorithm that can rapidly find communities within a graph representing information flows. We apply this algorithm to an initial e-mail corpus of nearly 1 million messages collected over a 2-month span, and show that the method is effective at identifying true communities, both formal and inform…
Status As a Valued Resource
The striving for status has long been recognized in sociology and economics. Extensive theoretical arguments and empirical evidence propose that people view status as a sign of competence and pursue it as a means to achieve power and resources. A small literature, however, based on arguments from biology and evolutionary psychology, proposes that people pursue status as an (emotional) goal in itself, independent of competence and expressed by cul…
The Laws of the Web
An accessible explanation of the hidden patterns found within the seemingly chaotic World Wide Web.Despite its haphazard growth, the Web hides powerful underlying regularities—from the organization of its links to the patterns found in its use by millions of users. Many of these regularities have been predicted on the basis of theoretical models based on a field of physics—statistical mechanics—that few would have thought applicable to the social…
A market for secrets
We propose an electronic market system for private data that guarantees levels of privacy, anonymity and control to individuals while maintaining the ability of other entities to mine their information and automatically pay individuals for their data. We also describe a novel procedure that allows data miners to anonymously contact the creators of the information in case their profiles are needed for future research
Free riding on Gnutella
An extensive analysis of user traffic on Gnutella shows a significant amount of free riding in the system. By sampling messages on the Gnutella network over a 24-hour period, we established that almost 70% of Gnutella users share no files, and nearly 50% of all responses are returned by the top 1% of sharing hosts. Furthermore, we found out that free riding is distributed evenly between domains, so that no one group contributes significantly more…
Distributed Computation as an Economic System
As computer networks grow and blanket the planet, they become a community of concurrent processes, which, in their interactions, strategies, and lack of perfect knowledge, become analogous to human market economies. Economics may thus offer new ways of designing and understanding the behavior of distributed computer systems

Formation en entreprise et débauchage de main d'oeuvre aux Etats-Unis
Nous proposons, dans cet article, un modèle dynamique d'action collective permettant d'étudier les conditions d'émergence d'un système de formation en entreprise dans l'économie américaine. Ce type de formation comporte certaines des caractéristiques d'un bien collectif et sa production soulève, de ce fait, un problème de coordination de type dilemme du prisonnier à n joueurs. Nous modéli-sons celui-ci à l'aide d'un formalisme emprunté à la méca…
The outbreak of cooperation
We study the ongoing collective action problem among intentional agents whose choices depend not only on the past but also on their expectations as to how their actions will affect those of others. In this model agents act on the basis of imperfect information. We show that under these conditions the onset of overall cooperation can take place in a sudden and unexpected way. Likewise, defection can appear out of nowhere in very large, previously …
