    • Positive externalities and network effects.
    • Pricing in two-sided markets.
    • Negative externalities and congestion pricing, information issues.
  3. Pricing Theory
    • Monopoly pricing, price discrimination, bundling, multipart tariffs.
    • Cost-based pricing: Subsidy-free prices and pricing in practice (LRIC, FDC).
  4. Economics of Network Protocols
    • Economics of flow control and bandwidth sharing.
    • TCP and fairness issues in the Internet.
  5. Regulation in Telecommunications
    • Pricing access networks, LLU.
  6. Interconnection in the Internet
    • Peering and transit agreements.
    • Peering games, paid peering.
  7. Competition in the Current Internet
    • Tussles in the Internet ecosystem, evolution of the Internet value chain.
