Syllabus

The rapid advancements in our ability to communicate across distances—driven by the evolution of communication technologies and the expanded capabilities of the internet and social media—have made social networks increasingly prominent. Understanding networks is crucial for examining how they influence behavior. Individuals often form relationships to connect with others for economic reasons, benefiting from collaboration, exchange, and information sharing.

Network economics provides a framework for analyzing the interactions of agents connected through a network and understanding how their behaviors are influenced by those around them. These lecture series highlight recent developments in network economics and peer effects, starting with the theoretical foundations and then focusing on practical applications in areas such as crime, education, and labor economics.

The 3,5 credit course spans 10 hours, comprising 5 lectures in one week, each lasting 2 hours.
