William W. Olney has a newly published paper on that topic, and it seems it helps a good deal:
This article investigates whether the global spread of the English language provides an inherent advantage to native English speakers. This question is studied within the context of the economics profession, where the impact of being a native English speaker on future publishing success is examined. English speakers may have an advantage because they are writing in their native language, the quality of writing is a crucial determinant of publishing success, and all the top economics journals are published in English. Using a ranking of the world’s top 2.5% of economists, this article confirms that native English speakers are ranked 100 spots higher (better) than similar non-native English speakers. A variety of extensions examine and dispel many other potential explanations.
“Similar” is a tricky word! How similar can a Frenchman be? I am not sure, but it does seem that growing up in the Anglo-American world may — language aside — be more conducive to patterns of thought which predict success in…the Anglo-American world. Nonetheless this is an interesting investigation, even if I am not entirely convinced. Note also that economics blogging is predominantly an Anglo-American enterprise, but I view that too as more about “mentality” than language per se.
For the pointer I thank the excellent Kevin Lewis.
