Abstract: We investigate divisions within the citation network in economics using citation data between 1990 and 2010. We consider all partitions of top institutions into two equal-sized clusters, and pick the one that minimizes cross-cluster citations. The strongest division is much stronger than could be expected to be found under idiosyncratic citation patterns, and is consistent with the reputed freshwater/saltwater division in macroeconomics. The division is stable over time, but varies across the fields of economics.

Keywords: citations; clustering; influence; schools of thought

JEL-codes: A11; D85; I23
