As of 2007, authors of the two best papers published in the IJIO volume of the previous year win a money prize, sponsored and selected by the IJIO Editorial Board. This award was initially named The Paul Geroski Best Paper Prize in memory of Paul Geroski (IJIO Co-Managing Editor, 1987-1992) who passed away in 2005; however, to avoid confusion with an EARIE best paper prize (YEEA) also dedicated to Paul Geroski, in 2013 the IJIO award reverted back to its generic name. Winners of the International Journal of Industrial Organization Best Paper Award are selected by the journal editors and announced in the last IJIO issue of each year.
