David Berri

David J. Berri (born September 26, 1969) is a

NBA basketball. He is a past president of the North American Association of Sports Economists, and a member of the editorial board of the Journal of Sports Economics

and The International Journal of Sport Finance.

Academic background

Berri graduated from

California State University-Bakersfield

before accepting a position at Southern Utah University in 2008.

Berri is best known for co-authoring, along with Martin Schmidt and Stacey Brook, the 2006 book The Wages of Wins: Taking Measure of the Many Myths in Modern Sport. The book opened to favorable reviews in several major media outlets, including endorsements from

NFL, and competitive balance in baseball

.

The portion of the book that has drawn the most attention—positive and negative—has been Berri's analysis of the

NBA, particularly with regard to player performance. By running a series of linear regressions

, Berri has developed a model called "Wins Produced", which "explains 95% of team wins". The Wins Produced model is a refinement of an earlier model put forth in a 1999 paper published in the journal "Managerial and Decision Economics.

Berri's work is frequently viewed as a lightning rod for criticism because the Wins Produced model often runs counter to the conventional wisdom of basketball. Berri has not discouraged such controversy, either, in his posts for The Wages of Wins' accompanying blog, "The Wages of Wins Journal", which frequently criticizes NBA decision-makers (i.e., coaches and general managers) and members of the media.

Criticism

Berri has come out in opposition of certain traditional

Player Efficiency Rating, a model that Berri also argues significantly undervalues shooting efficiency. He has also criticized non-box score-based stats like Adjusted Plus-Minus, claiming that the basic box score numbers tell decision-makers most of what they need to know about a player's value. In December 2011, Berri released an updated version that adjusted the defensive rebound weight to account for diminishing returns.^[1]

Berri has provided data on women's basketball for the journal The Ladies League as well as several other media outlets.
