CoFE - Collaboration in Financial Economics

What is this?

I have collected acknowledgement sections from all research papers published between 1997 and 2011 in the following six journals: The Journal of Finance, The Review of Financial Studies, Journal of Financial Economics, Journal of Financial Intermediation, Journal of Money, Credit & Banking, Journal of Banking and Finance.

The data contain consolidated and hand-checked information on 14,531 researchers:

14,531 researchers in the dataset

We used it to construct and study the network of informal collaboration:

The network from 2009 to 2011

You can explore interactively at www.central-places.net.

Where do I find information?

The data, how we collected it and what it can be used for, is described in detail in Georg, Co-Pierre and Rose, Michael E. (2018): "What 5,000 Acknowledgements Tell Us About Informal Collaboration in Financial Economics", Max Planck Institute for Innovation & Competition Discussion Paper No. 11. (PDF) When using this data, please cite the article.

How do I use this?

The file you're after is acks_min.json.

In Python, you can get the most recent version of the data like so

from json import loads
from urllib.request import urlopen

COFE = 'https://raw.githubusercontent.com/Michael-E-Rose/CoFE/master/acks_min.json'

acks = loads(urlopen(COFE).read().decode("utf-8"))['data']

acks is a list of dictionaries (entries explained below). You can iterate over the items to generate a network with networkx:

from itertools import product

import networkx as nx

G = nx.Graph()
for item in acks:
    # Authors
    auths = [a['label'] for a in item['authors']]
    G.add_nodes_from(coms)
    # Commenters
    coms = [c['label'] for c in item.get('com', [])]
    G.add_nodes_from(coms)
    # Links
    links = list(product(coms, auths))
    G.add_edges_from(links)

Filelist

  • acks.json is a hierarchically organized json file listing all information we have for each article (see variable list below). The primary is key is always the title of the article.
  • acks_min.json is a minimized version of acks.json (no idents and superfluous blanks).
  • consolidate_acks.py generates above two files using data in folder data.
