An Empirical Analysis of Filesharing

Olson’s Paradox Revisited : An Empirical Analysis of Filesharing
Thierry Pénard, Sylvain Dejean, Raphaël Suire (June, 2009)

Abstract:

This article aims to examine the impact of group size on the provision of collective good provided by P2P file-sharing communities. Olson (1965) argued that small communities are more able to provide collective actions. Using an original database on Bittorrent file-sharing communities, our article finds a positive relation between the size of a community and the amount of collective good provided. However, the individual propensity to cooperate decreases with group size. These two features seem to indicate that P2P file-sharing communities provide a pure (non rival) public good. We also show that specialized communities are more efficient than general communities to encourage cooperative behavior. Finally, the rules designed by the managers of a community play an active role to stimulate voluntary contributions and improve the self-sustainability of file-sharing.

UNU-Merit Survey of Wikipedia Readers and Contributors

Rishab Aiyer Ghosh 's Groups, UNU-MERIT, has done a large survery of wikipedia readers and contributors (130'000 completed surveys). Among the key (preliminary) results with regard to gender are:

  • Readers and contributors are on average in their mid-twenties, and predominantly male (75%)
  • Women, with a share of 25% in all respondents, are more strongly
    represented among readers (32%) and less strongly represented among
    contributors (13%).

hexagon.cc: file-sharing goes semi-private

Perhaps the days of the general file sharing nodes, like piratebay, isohunt, or even mininova are over. But certainly not the days of unregulated file-sharing. As far as one can tell, private-trackers are thriving and now the founder of isohunt is creating a new system called hexagon.cc which centers around the ability of users to create groups of people with whom they want to share.

torrentfreak.org wirtes: “The main difference that sets Hexagon.cc apart from other social file sharing and BitTorrent sites, is everything is centered around groups. Be it file sharing networks or flash video sites, a key piece we found missing is social context,” isoHunt’s founder Gary Fung said.

With Hexagon Fung hopes to bridge this gap by allowing people to
start groups where they can share content within a certain niche. These groups help to organize content and allow people to share with others who are interested in the same material, privately or in public.

The Internet has not transformed civic engagement... yet

Ars Technica reports on the new study The Internet and Civic Engagement which found that there is a strong correlation between income and political activity and that there is little difference between online and offline, except that online more people sign petitions. Looks like the Internet is not really broadening the social basis of political involvement.

Collaborative Filtering with Ensembles

Article on new collaborative platforms for software development

One of the most interesting insights from the results of the Netflix challenge is that while the algorithms, the psychology, and good knowledge of statistics goes a long way, it was ultimately the cross-team collaboration that ended the contest. "The Ensemble" team, appropriately named for the technique they used to merge their results consists of over 30 people. Likewise, the runner up team ("BellKor") is a collaborative effort of several distinct groups that merged their results. It is easy to overlook this fact, except that it is not a one-time occurrence. The leaderboard for the recent GitHub contest also clearly shows over half of the top ten entries as ensemble techniques!

The Benefits of Weak Copyright

File-Sharing and Copyright, by Felix Oberholzer-Gee and Koleman Strumpf, Harvard Business School, Working Paper 09-132

From the Introduction:

The advent of file-sharing technology has allowed consumers to copy music, books, video games and other protected works on an unprecedented scale at minimal cost. In this essay, we ask whether the new technology has undermined the incentives of authors and entertainment companies to create, market and distribute new works. While the empirical evidence of the effect of file sharing on sales is mixed, many studies conclude that music piracy can perhaps explain as much as one fifth of the recent decline in industry sales. A displacement of sales alone, however, is not sufficient to conclude that authors have weaker incentives to create new works. File sharing also influences the markets for concerts, electronics and communications infrastructure. For example, the technology increased concert prices, enticing artists to tour more often and, ultimately, raising their overall income.

Data on the supply of new works are consistent with our argument that file sharing did not discourage authors and publishers.
