Energy Finance Christmas Workshop (EFC11)

19-20.12.2011, Wrocław, Poland

The series of Energy Finance Christmas workshops started back in 2011, when I invited two of my colleagues and good friends - Stefan Trück and Sjur Westgaard - to give talks at the Science meets Social Science (S3) seminar. Stefan and Sjur promptly accepted the invitations, but later started changing dates of their stay in Wrocław. After lengthy negotiations it turned out they both wanted to come in the same week, right before Christmas! To resolve the 'crisis' I decided to invite a few more colleagues, organize a workshop and call it the Energy Finance Christmas Workshop. The EFC11 held on December 19th and 20th turned out to be a great success ... to the extent that Stefan concluded his talk by saying: See you all next year in Sydney for EFC12!
