GTAP Data Bases: Format Specifications
There are two formats in which GTAP tables may be submitted, 1) the new unified version, and 2) the original version. We also provided tables showing how the two formats are linked (see below), and a utility to move from the old to the new format (visit the Utilities page).A table is also available which shows the relationship between the original format and the GTAP Data Base.
