The MAGNET model ([[van Meijl, 2006]]) is based on the standard GTAP model ([[Hertel, 1997]]), which is a multi-regional, static, applied computable general equilibrium ([[hasAcronym::CGE]]) model based on neoclassical microeconomic theory. MAGNET is a further development of GTAP regarding land use, private consumption, livestock, food, feed and energy crop production, and emission reduction cost curves.

MAGNET distinguishes single European countries and, outside Europe, 22 large world regions, closely matching the IMAGE regions [[IMAGE region (background category)]]. Similar to most other CGE models, MAGNET assumes that products traded internationally are differentiated according to country of origin, i.e. domestic and foreign products are not perfectly identical, but imperfect substitutes (the so-called Armington assumption ([[Armington, 1969]]). | MAGNET distinguishes single European countries and, outside Europe, 22 large world regions, closely matching the IMAGE regions [[IMAGE region (background category)]].

Additional to the standard GTAP model, MAGNET includes a dynamic land supply function ([[van Meijl, 2006]]) which accounts for the availability and suitability of land for agricultural use, based on information from IMAGE (see | Additional to the standard GTAP model, MAGNET includes a dynamic land supply function ([[van Meijl, 2006]]) which accounts for the availability and suitability of land for agricultural use, based on information from IMAGE (see [[Flowchart AEF]]) ). A nested land use structure accounts for the different degrees of substitutability between types of land use ([[Huang, 2004]];[[van Meijl, 2006]]), and includes an imperfect mobility of capital and labour between agricultural and non-agricultural sectors ([[Hertel, 2003]]). In addition, the MAGNET model includes international and EU agricultural policies, such as quota and import tariffs ([[Helming, 2010]]). | ||
Biofuel crops: MAGNET includes first-generation biofuels ([[Banse, 2008]]), and the use of by-products of biofuel production in the livestock sector. | Biofuel crops: MAGNET includes first-generation biofuels ([[Banse, 2008]]), and the use of by-products of biofuel production in the livestock sector. | ||
