The derivation of conditions under which the degree distribution of these constructs is scale-free is the subject of research by Matt Jackson.
The inequality in these constructs for mothers who enroll kids in childcare is one example of them discussed in Unanticipated Gains by Mario Small. They explain persistent income variation by geography in the former West Germany following reunification in a paper by K.B. Burchardi and T.A. Hassan. Thomas Chaney added a second "geography" dimension to a family of models of these constructs in which they grow in a two-stage process that begins with a uniform draw over previous generations. The derivation of conditions under which the degree distribution of these constructs is scale-free is the subject of research by Matt Jackson. These constructs, which have been used to analyze physics citations and racial dating patterns in high school, were studied in an experiment in which people in Omaha or Wichita received envelopes bound for Boston. Stanley Milgram's small world experiments studied the path lengths of, for 10 points, what constructs that can explain success in gaining employment?
