Course Details: Level 300
Recommended Semester Credits: 1
Contact Hours: 20
DESCRIPTION
Learn about recent econometric methods to analyze network data. Networks play an increasingly dominant role in many social, business, and economic environments. Moreover, network data becomes increasingly important and available due to the rise of online social media and digitization.
The course will combine online lectures with hands-on empirical and programming exercises.
Upon successful completion of the course, students will:
- become acquainted with different statistical methodologies for analysing networks while learning how to see these different methodologies complementing each other.
- learn to model network problem situations mathematically, and adapt the methods learned to new situations at hand.
- be able to recognise, understand, and analyse societal and business problems in which networks are central.
- learn how networks affect supply and demand in markets, how this leads to market failures, and how government policies can address these.
