Economics Research Rankings for Missouri

RePEc (Research Papers in Economics) is an extremely valuable resource for economists. Produced by volunteers from around the world, it's a database of working papers, journal articles, books, etc. that's become the go-to place for everything about economics research past and present.

It was inevitable that this data would be used to create rankings of journals, departments, and even individual economists. These rankings have been sliced and diced by field, country, region, state, type of item, sex, graduation cohort, and even deceasedness. Below is the current ranking of university economics departments in Missouri:

RankDepartment, UniversityScore
1Dept of Economics, Washington Univ in St. Louis3.19
2Olin School of Business, Washington Univ in St. Louis4.16
3Economics Department, Univ of Missouri5.05
4Center for Economics & the Environment, Lindenwood Univ7.92
5Dept of Economics, Univ of Missouri-St. Louis10.92
6John Cook School of Business, St. Louis Univ13.72

Note that I have excluded the state's two Feds in Missouri because of the difficulty in figuring out who actually works in which division and because their lists of people include some who are just visiting scholars. Thus, their RePEc rankings are not terribly informative. Given that the two Feds account for a significant portion of the economics research done in the state, this is unfortunate.

In addition, RePEc's overall ranking methodology suffers from a severe case of information kitchen-sinkism. That is, the department rankings are determined by the harmonic average of 33 rankings, some of which are of questionable importance, and many of which are little more than minor variations of each other. Specifically, the 33 rankings include seven variations on the number of works, 12 variations on the number of citations, six variations on the number of pages, two variations on the number of citing authors, two variations for each of abstract views and downloads from the RePEc site, a measure of the success of graduate students, and the department H-index.

The rankings of individual economists are burdened by four additional sub-rankings: the closeness and betweenness measures of one's co-authorship network, the breadth of citations across fields, and the Wu-index. The its credit, the site allows you to choose criteria of your own, but you only get the world's top 5% for each.

I've created a more-useful ranking of Missouri's departments using individual economist's H-indices from the CitEc project, which contains RePEc's raw data on citations. The H-index is a simple and popular measure that is meant to capture both the quantity and impact of an author's body of work. From Wikipedia:
The definition of the index is that a scholar with an index of h has published h papers each of which has been cited in other papers at least h times.
Note that I include each author's primary affiliation only, and, to fix inconsistencies in how authors chose their affiliation, each author was assigned to a specific department within a Fed or University. Here are the top 25% of research economists in Missouri according to their H-indexes:

One way to obtain department rankings from individual rankings is to take an average of the H-index for the economists within a department. Doing so would give an upward bias to departments like mine, which is small and has a skewed distribution of H-indices (i.e., we skew old). So, instead, I also used the department H-index, which benefits large departments while also trimming the high end of the distribution. A department's score is then the sum of these two Hs relative to the maximum across departments. The result is ranking that includes the two Feds and the 11 departments in Missouri with at least 2 authors registered with RePEc:

1Olin School of Business, Washington U100
2Dept of Economics, Washington U92
3Research Division, St Louis Fed91
4Dept of Economics, U of Missouri76
5Center for Econ & the Environment, Lindenwood U62
6Research Division, Kansas City Fed55
7Center for Household Financial Stability, St Louis Fed53

10Dept of Economics, UM-Kansas City32
