Goyal, Van Der Leij and Moraga-Gonzalez (JPE 2006) and a
Comparison of Econlit and Scopus", Journal of Applied Econometrics,
Vol. 37, No. 4, 2022, pp. 820-828.

The entire code and data repository may be found in mr-files.zip. All
text files are in DOS format, so Unix/Linux users should use "unzip -a".
  
I am not able to share the pure publication records of EconLit, nor
the original files used by the authors nor the pure Scopus records.  I
provide instructions on how to get these, and what to do with all of
them.  However, I include the network files in the repository, because
I am able to share these.

-- The authors show the evolution of the co-author network of Economists

-- They study three networks, where each network corresponds to a decade:
1970s, 1980s, 1990s

-- Publications originate from the EconLit

-- I use Scopus data instead, but look at the same journals, and I
also add 2000s and 2010s

To replicate:

1. Install packages as defined in [`./requirements.txt`](requirements.txt)

2. Query EconLit to obtain their publication lists since 1970, as described
in [`./000_EconLit_data/README.md`](./000_EconLit_data/README.md)

3. Optionally, obtain the network files used by the authors of the original
study and place them in folder
[`./005_original_pajek/`](./005_original_pajek/)

4. Configure [pybliometrics](https://pybliometrics.readthedocs.io/en/stable/),
i.e. obtain API key and assure you have access to their API

5. Execute scripts in ascending order

Each folder contains readme files as well, and there is also a file listing
the software requirements.
