Bleg: Know any good referee studies?

I've been invited to this year's MIT Sloan Sports Analytics Conference, to participate in the "Referee Analytics" panel. I guess if I'm going to be talking about refereeing, I should try to get up to date on some of the research that's been going on.

So, a bleg: could you guys refer me, either in the comments or online, to what you think is important research on refereeing/umpiring in any sport? Much appreciated.

Oh, and speaking of umpiring ... a couple of years back, I had a nine-post analysis of the study about umpires and racial discrimination. Recently, I distilled those posts into an article that ran in the Fall, 2010 issue of SABR's "Baseball Research Journal."

Here's a .PDF of that article. I recommend it over my original posts ... back then, I was trying to figure it out as I was going along. This article is a distillation of the analysis, and what I actually concluded. (If you do want the original posts, they're linked at my website.)

And, by the way, SABR has an archive of past BRJ articles. It's a pretty good resource. There's at least one Bill James piece, for instance.

Racial Discrimination Among NBA Referees by Joseph Price and Justin Wolfers was the subject of a lot of attention a couple of years ago.

That Wolfers study is the one that comes to my mind as well. I looked at NBA refs once, but it was very poor(!), so don't go reading that.

So although I can't add anything to help you here, I look forward to seeing you in Boston!

Thanks, anon and Ryan. I remember blogging that one, I'll re-read it.

Ryan Boyko of Harvard published an analysis of home field soccer referee bias. Alexander Kranjec published an analysis of left versus right moving bias in soccer officiating.

A guest blogger on Freakonomics wrote about home-field advantage being based on referee bias. They mention a natural experiment where crowds weren't allowed to attend games in Italy and home-field advantage disappeared as did ref bias (not sure how it's measured in soccer). They also mention a study based on pitchFX of how refs tend to call balls as strikes and strikes as balls more often to benefit the home team. I don't know who did the original studies but it might mention it there.

Soccer by the numbers Has a study of home/away fouls in English Premier Soccer League. Also see Soccer by the Numbers referees.
He also has a post on cards home vs away at
Yellow cards
German Soccer is the abstract for a major study of the German Soccer league.
There seems to be a difference between the English and German Leagues based on comparing the abstract and the soccer by the numbers data.

Phil,

I performed a (non-academic) study of umpire bias on calling balls and strikes that appears in this year's THT Annual.

cheers,

I summarized and linked to a lot of the existing research on umpire strike zones and gave my viewpoint here:
