Abstract
This paper provides a detailed comparison between the graphical interfaces and post-model analysis tools of three large economic models: Aglink-Cosimo, CAPRI and GTAP. Whereas the Aglink-Cosimo and CAPRI models follow a strict separation between model and data analysis software tools, the GTAP model follows a model integrated approach using GEMPACK commercialized tools. Moreover, the CAPRI graphical user interface technically and formally detached from the data generation process. Aglink-Cosimo and GTAP use tools specifically developed to serve mainly their own needs (and tailored to communicate with their model drivers). One specific characteristic of Aglink-Cosimo relates to the need of interactive documentation for users, which relies upon the obligation of the OECD and FAO to deliver to the formalized Aglink-Cosimo user group a transparent and welldocumented model and database. The CAPRI and GTAP models are much more research-driven and therefore have invested more resources in building bridges with other model consortia.
