本文描述了一个基于全球贸易分析项目（GTAP）数据集的经济均衡模型在通用代数建模语言（GAMS）中的实现。我们称这个模型和辅助编程工具GTAPinGAMS。相对于GTAPinGAMS的前几期，该模型的创新之处在于它可以在全球多区域（GMR）和小型开放经济体（SOE）关闭之间轻松切换。我们还包括评估结果的可能性，最终需求的替代表示，基于柯布-道格拉斯，线性支出系统或弹性需求系统的恒定差异。在本文中，我们概述了模型的结构，文件相关的平衡条件，并描述了计算机程序校准模型所需的区域和部门的GTAP 9数据集的聚集。我们进行了一些计算，说明如何替代结构性假设的影响，从模型得出的政策结论。
This paper describes the implementation in the General Algebraic Modeling Language (GAMS) of an economic equilibrium model based on the Global Trade Analysis Project (GTAP) dataset. We call this model and the ancillary programming tools GTAPinGAMS. Relative to previous installments of GTAPinGAMS, an innovation in this model is that it can easily switch between global multiregional (GMR) and small open economy (SOE) closures. We also include the possibility to evaluate results for alternative representations of final demand, based on Cobb-Douglas, linear expenditure system or constant difference in elasticities demand systems. In this paper we outline the model structure, document the associated equilibrium conditions and describe computer programs which calibrate the model to the desired regional and sectoral aggregation from the GTAP 9 dataset. We perform a few calculations which illustrate how alternative structural assumptions influence the policy conclusions derived from the model.
