Dear DRUID Director, My name is Pilar Bernal, an assistant professor from the University of Zaragoza (Spain). I am writing you with respect to a paper entitled "UNDERSTANDING THE INNOVATIVE BEHAVIOR OF FIRMS: THE EFFECT OF PERSISTENCE DECISIONS ON INNOVATION PERFORMANCE", which has been presented in the DRUID19 Conference (June 19-21, 2019). This paper, jointly developed with my coauthors Juan P. Maicas and Pilar Vargas, is published in the website of DRUID, because of our participation in the conference. We were wondering whether the publication of the paper in the druid portal can be eliminated. Thank you very much for your time. We are really looking forward to hearing from you, Yours sincerely, Pilar Bernal, Juan P. Maicas and Pilar Vargas
