Dear organizing committee of DRUID, My name is Georgios Tsiachtsiras and I submitted the Paper ID: 5720 , Paper title: " Transportation Networks and the Rise of the Knowledge Economy in 19th Century France ". I received the email that the paper was accepted for presentation. As I was trying to upload a more recent version of the paper, I accidentally deleted the paper. I do not know how to fix this issue. Do you want me to send the recent version of the paper to you? Thank you in advance for your consideration, Kind Regards, George Georgios Tsiachtsiras Ph.D. Candidate in Economics Personal Webpage: https://sites.google.com/view/gtsiachtsiras<https://sites.google.com/view/gtsiachtsiras/home> University of Barcelona (UB) - Faculty of Economics and Business - Department of Econometrics, Statistics and Applied Economics - Regional Quantitative Analysis Group (AQR) Av.
