Today's Internet industry suffers from several well-known pathologies, but none is as destructive in the long term as its resistance to evolution. Rather than introducing new services, ISPs are presently moving towards greater commoditization. It is apparent that the network's primitive system of contracts does not align incentives properly. In this study,(More)
In an instructional setting it can be difficult to accurately assess the quality of information visualizations of several variables. Instead of a standard design critique, an alternative is to ask potential readers of the chart to answer questions about it. A controlled study with 47 participants shows a good correlation between aggregated novice heuristic(More)
User-directed routing technologies - that is, systems in which users choose their own routes through a communications network - have generated considerable interest in recent years. Despite their numerous theoretical advantages, ISPs have so far resisted these technologies, even as users have learned to capture some routing power through overlay networks.(More)
The difficulty of making changes to the internet architecture has spawned widespread interest in virtualized testbeds as a place to deploy new services. Despite the excitement, uncertainty surrounds the question of how technologies can bridge the gap from testbed to global availability. It is recognized that no amount of validation will spur today's ISPs to(More)
The rise of peer-to-peer networks has dramatically altered the way consumers interact with digital content. Most visibly, pirate downloads substitute for legal purchases, eroding profits and calling into question the very viability of content production. This characterization has motivated a detect-and-punish model that aims to make pirate networks less(More)
A new generation of technologies allows firms to track online consumer behavior with increasing granularity, and to share this information with other firms. This promise of information sharing has driven considerable interest from firms; and its potential for mone-tization has allowed a large number of online and web services to be available free of charge(More)
We develop a stylized model that describes government surveillance, its effect on rational government actions, and the implications for citizens. Our model treats government as a rational actor that chooses how much to abuse its power, to prevent being voted out or overthrown. Starting with only limited directional assumptions, we prove a robust implication(More)
The question of how to simultaneously promote growth and diffusion of ideas exhibits difficult yet pressing tradeoffs. To economists, it concerns the relationship between economic health and incentives for sharing information. When does the stimulus to innovation, founded on a profit motive, collide with access to information source material, which exhibits(More)
