(2022). Small World: Narrow, Wide, and Long Replication of Goyal, Van Der Leij and Moraga-Gonzélez (Jpe 2006) and a Comparison of Econlit and Scopus Journal of Applied Econometrics, 37 (4), 820-828.
I undertake a narrow, wide, and long replication of Goyal, van der Leij and Moraga-Gonzélez (2006, https://doi.org/10.1086/500990). Using social network analysis, they show that the Economics profession gradually evolved into a small world. Small worlds (or small world networks) have unique information transmission capabilities. The trend is explained by the emergence of frequently publishing researchers with many distinct co-authors. In a social network, they resemble stars. The original results are robust to the usage of (I) another software, (II) a recent version of the originally used data, and (III) another database and a more sophisticated author disambiguation.
