Early versions of the DICE model (GAMS only)

Note that these are not documented in the files. You will need to go back to the source publications to get the exact dating. The major differences are the start date of the runs (from 1965 to 2005); and the price level (from 1989 US $ to 2005 US international $).

1. The earliest available model that is running is "DICE123," first written in 1992. This version has been cleaned up slightly to make it easier to understand for users. Click here for DICE123.

2. The 2007 version from A Question of Balance (Yale University Press) is available here. This is a self-contained version that contains the major runs but not some of the more complicated ones. Click here for the 2007 version.
