Dr. Lennart Kraft
My interests comprise the economic, technical, and legal perspective on data on the internet. I research the relevance of data in online advertising markets for consumers (e.g., online privacy), firms (e.g., targeted advertisements and content personalization) and regulators (e.g., market efficiency). Methodologically, I build upon econometrics and machine learning in cross-sectional and longitudinal settings, often using extensive field data.
