Recently I fell in love with social network... Therefore, it is unavoidable to add some social network analysis results into my graduation thesis. Here are some interesting graphs used in my paper, which I would like to share with you online. They are all about "the social network of economists", i.e. the academic circle of economics.
Full view of the economists' world, without labels.
The bigger size of nodes denotes the higher level of connections with others (degree/pagerank). (2000-present). An expandable vector diagram can be download here: all_10_nolabel.pdf
Full view of economists' world, with grey edges (2000-present)

Note: I'm sorry that there are still some technical problems in my graphs.
The most important points are the order and abbreviation of names, like Peter C.B. Phillips and Phillips, Peter C.B. I haven't got a good idea how to deal with this...Google Scholar considers "Coo Boo" as "C Boo", so all person with same family name and the first letter of given name may regarded as one person. RePEc uses the similar way but they let the authors themselves to identify which are actually their works. I will refine these problems as soon as I got a good idea.
