This thrust explores the interface between computer science and economics, focusing on how computational systems interact with agents in large-scale networks and marketplaces. Research includes algorithmic game theory, mechanism design, decentralized decision-making, approximation algorithms, and economic aspects of networked and distributed systems. These methods have broad applications in online markets, financial networks, resource allocation, and multi-agent systems. Representative topics include:

• Algorithmic game theory
• Mechanism design
• Strategic agents in networks
• Economics of distributed systems
• Approximation and optimization algorithms
• Computational finance and financial networks
