We study the evolution of social distance among economists over the period 1970–2000. While the number of economists has more than doubled, the distance between them, which was already small, has declined significantly. The key to understanding the short average distances is the observation that economics is spanned by a collection of interlinked stars. A star is an economist who writes with many other economists, most of whom have few coauthors and generally do not write with each other.

The Global Arms Trade Network 1950-2007 (2012, background): “The diameter increases as well but remains very low throughout the sample, a feature of many networks often referred to as the small world property, see for instance Goyal et al. (2006).”

Small Worlds and Regional Innovation (2007, background): “Such a dominant largest component size is not without precedent, for example, 50% of the entire network for economics collaboration networks (Goyal et al. 2004), and 90% and 100% for Canadian investment banks (Baum, Shipilov, and Rowley 2003).”
The Economic Consequences of Social Network Structure (2017, unknown): “See, in particular, Jackson (2003, 2004, 2005, 2011), Ioannides and Datcher-Loury (2004), Granovetter (2005), Jackson and Yariv (2011), Jackson and Zenou (2015), as well as the books by Demange and Wooders (2003), Vega-Redondo (2007), Goyal (2007), Jackson (2008a), Benhabib, Bisin and Jackson (2011)”
Development and social capital (2006, background): “Inefficiency will also be large when sub-groups who could trade with each other are unconnected, even if many links exist within each sub-group (e.g., Bloch et al., 2004; Goyal et al., 2004).”
Identification of Peer Effects through Social Networks (2009, unknown): “Thus, studies on co-authorship networks among scientists are linked to the availability of literature databases (see Newman (2001) and Goyal et al. (2006)). Sampling the network provides a different way to reduce these costs. This can be done in many ways, e.g., see Rothenberg (1995). It would be in”

Social distance versus spatial distance in R & D cooperation: Empirical evidence from European collaboration choices in micro and nanotechnologies (2007, background): “Very few authors propose empirical studies based on this theoretical background (see Goyal et al. 2006; and Van der Leij et al. 2006).”
Does Co‐authorship Lead to Higher Academic Productivity? (2015, unknown): “Specialization allows a scientist to become an authority on a given subject (Hackett, 2005).”
