Earlier versions of the program were written by Andrew Harvey and Simon Peters, while the data management side was dealt with by Bahram Pesaran. These projects were supported by the Economic and Social Research Council. Version 5 was entirely rewritten in C by the current authors of STAMP. Much of the data management and the graphical interface of STAMP 5 was shared with the PcGive 7 and 8 programs of Jurgen A. Doornik and David F. Hendry. STAMP 6 was the first version of STAMP in which the front-end program GiveWin is separate from the econometric module STAMP.
The history of STAMP goes back to the 80's! See below for some screenshots of the program from the old days.
