Potent dangers to the growth and health of the Internet involve a human element and require understanding of Internet economic issues. The Internet as an economy currently includes about 50,000 organizations that interconnect their communication infrastructures to provide the global Internet service to more than 3 billion users. The interconnection structure and economic relationships between the organizations have deep implications for performance and security, e.g., for traffic routing through the Internet and resilience of the Internet service to failures and attacks. Our research in Internet economics studies individual interests of Internet players, tensions between these interests, incentives for cooperation, and mechanisms for improving the social welfare.
The NetEcon Group at IMDEA Networks Institute studies economics of networked systems and its interplay with technology and security. Based on measurements, data analysis, and modeling, the group explores the roles and interactions of various entities in the Internet ecosystem. We also develop innovative business models for cost reduction, revenue increase, and social utility maximization.
