I am the Jacob Wallenberg Professor at the Stockholm School of Economics. My research focuses on imperfectly competitive markets (Industrial Organization) with an emphasis on investigating responses by firms to uncertainty and various risks, in particular exchange rate risk. I teach microeconomics at the undergraduate level and Industrial Organization at the PhD level. I am also affiliated (Professor II) with NHH in Bergen. A CV is available here.
NEW! I've just completed a first full draft of a textbook suited for introductory or intermediate level courses in microeconomics that I intend to publish open source. A key feature is that many of the figures and tables contain links to explanatory step-by-step Youtube recordings. The book is available here.
