The academic labor market is analyzed as a citation network, where departments gain citations by placing their Ph.D. graduates into the faculty of other departments. The aim is to measure the distribution of influence and the possible division into clusters between academic departments in three disciplines (economics, mathematics, and comparative literature). Departmental influence is measured by a method similar to that used by Google to rank web pages. In all disciplines, the distribution of influence is significantly more skewed than the distribution of academic placements, due to a strong hierarchy of schools in which movements are seldom upwards. This hierarchy is strongest in economics. It is also found that, in economics, there are clusters of departments that are significantly more connected within than with each other. These clusters are consistent with anecdotal evidence about Freshwater and Saltwater schools of thought. There is a similar although weaker division within comparative literature, but not within mathematics.
