Thereafter, the group was formalized by confidential elections of the Executive Committee, and by-laws of the EUDN have been developed. The core of the network initially consisted of 17 development economists, most of whom are embedded in a multidisciplinary environment at their home institutes. Further disciplines were included at a later stage.
The official announcement about the new European network was made at the Second Annual GDN Conference in Tokyo in December 2000. While in Tokyo, it was also decided at the first meeting of the Executive Committee
- to call the new European hub the European Development Research Network, in short EUDN and
- to expand the network by carefully enlarging the group of 17 development economists.
In the following years, three round of nominations and elections of new members took place. In June 2001, the network was expanded by 13 new members; in December 2002, 17 new members followed, and in April 2004, another 7 members joined. In September 2006, 13 full members and 4 associate members have been accepted. Allowing for withdrawals of a few members, total membership is now equal to 84 full members and 33 associate members (2017).
