2008-06: There is now a pdf version of these comments available. This may be a better way to read this as some people have reported difficulties with viewing the maths in the page (requires mathml support – via firefox + mathml fonts or IE).
Back last October I was a participant in a “Networks” reading group that worked through “An Economic Model of Friendship: Homophily, Minorities and Segregation†by Currarini, Jackson and Pin (2007). The discussion at the time encouraged me to expend some effort in order to try and derive some of the paper’s results in what I believe is a simpler, and more intuitive, manner.
Having finally got round to writing/marking up my rough notes into computer friendly format (markdown + latexmathml) I’ve now posted them online at:
