I am extremely grateful to Prof. Szymaski for his willingness to share his data. It is part of a much larger data set he and his research group will use to study more than 40 years of English soccer from multiple economics angles. I will keep you informed of any papers or books he publishes, as I am sure they will contain wonderful insights that will go way beyond my one dimensional analysis at the TPI blog.
Finally, I am extremely appreciative of Prof. Szymaski's and Simon Kuper's continuing dialogue on this topic. It's clear that both of them have a different opinion than the authors of the TPI as to the relative impact of transfer fees on the game of soccer. Nonetheless, we have an ongoing and continual dialogue via email and interviews, with the latest installment of the running dialogue found in Kuper's and Szymanski's expanded and updated second edition of Soccernomics that was released yesterday. I picked up my copy on its release date, and as a humble brag I would recommend checking out page 413 of the book to see their thoughts on the TPI. I will be pouring through the book in the next two weeks in preparation for an interview with both men that will hopefully shed more light on the topics contained in its covers. Based upon what I was able to preview via Amazon's "Look Inside" feature, I highly recommend you pick up a copy as well and see what's contained in the additional 100 pages of material.
