Divisions within Academia: Evidence from Faculty Hiring and Placement
研究了经济学、数学和比较文学三个学科中院系间的招聘模式，发现经济学内部存在显著且稳定的分裂（如淡水学派与咸水学派），比较文学也有分裂，但顶尖数学系的招聘模式接近随机匹配。
I look for divisions to clusters among academic departments in three disciplines: economics, mathematics, and comparative literature. I define clusters as subsets of departments with unexpectedly little hiring across the cluster lines. The division within economics is by far the strongest, is consistent with anecdotal evidence about “freshwater” and “saltwater” schools of thought and has been stable over time. There is also a significant division within comparative literature, but the hiring patterns among top mathematics departments are consistent with random matching. © 2011 The President and Fellows of Harvard College and the Massachusetts Institute of Technology.
