阿肯色全球水稻模型是基于多国统计模拟和计量经济学框架。该模型由六个子区域组成。这些地区是美国、南亚、北亚和中东、美洲、非洲和欧洲。每个区域由几个国家组成，每个国家模型都有一个供应部门、一个需求部门、一个贸易、库存和价格联系方程。本模型中使用的所有方程均使用计量经济学程序或恒等式进行估计。估计是根据一系列解释变量作出的，包括外生宏观经济因素，如收入、人口、通货膨胀率、技术发展，特别是政府决定的政策变量，这些政策变量反映了各国干预其稻米部门经济的各种机制。更具体地说，阿肯色全球大米模型是世界大米经济的代表。它被指定为一系列六个区域模型，每个模型都有类似的结构，其中内生关系解释了决定大米需求、供应、贸易和价格的经济因素。然后通过净贸易将个别国家模式联系起来，这突出了世界大米经济中各国的相互依存关系。
The Arkansas Global Rice Model is based on a multi-country statistical simulation and econometric framework. The model consists of six sub regions. These regions are the U.S., South Asia, North Asia and the Middle East, the Americas, Africa and Europe. Each region comprises of several countries and each country model has a supply sector, a demand sector, a trade, stocks and price linkage equations. All equations used in this model were estimated using econometric procedures or identities. Estimates are based upon a set of explanatory variables including exogenous macroeconomic factors such as income, population, inflation rate, technology development, and especially, government determined policy variables which reflect the various mechanisms by which countries intervene in their rice sector economy. More specifically, the Arkansas Global Rice Model is a representation of the world rice economy. It is specified as a series of six regional models, each having a similar structure within which endogenous relationships explain the economic factors determining rice demand, supply, trade and prices. Individual country models are then linked through net trade that highlights the interdependence of countries in the world rice economy.
