澳洲 Victoria University 大學研發的GEMPACK (General Equilibrium Modelling PACKage) 軟體,是一套多用途的經濟建模套裝軟體,特別適用於一般和局部均衡模型,並可以處理廣泛的經濟行為。GEMPACK 可以建立並運用可計算一般均衡模型(computable general equilibrium, CGE, model),並且具有求解過程簡單、可變動模組,及適用於政策分析等特點。
該方法在經歷 60 年代的短暫沉寂後,自90 年代開始,迅速成為政策分析的重要方法,廣泛應用於貿易政策、稅制改革、環境能源、產業政策 等方面的分析。在國外,對這種分析方法的關注正呈上升趨勢,一些政府機構、科研單位和高等院校正努力加強這方面的研究。
GEMPACK使建模者能夠求解非常大型的非線性方程式。
一旦模型方程式被使用一種類似符號的語言指定後,建模者就可以擺脫求解過程的計算細節。
GEMPACK軟體計算經濟模型的準確的解答。
所有的功能(基礎和高級)都有完整的文字說明、詳細的指令(包括許多手工操作示例)幫助新用戶快速入門。
GEMPACK Windows套裝程式可以幫助您視覺化、探索編碼、資料和結果。
GEMPACK 包含了強大的用於求解recursive-dynamic 和 fully-intertemporal 的能力
當出現問題會提示您發送回饋。
GEMPACK是非常有用的教學工具。
GEMPACK被超過90個國家的超過400個組織使用。
GEMPACK會不斷地持續改善。
新版介紹
Release 12.1 includes new automatic homogeneity testing, further improvements to LU decomposition performance, faster GEMSIM, enhanced searching in the Tabmate editor, improvements to ViewHAR and ViewSOL and faster start times for graphical interface (GUI) programs. As well many small bugs introduced in release 12.0 have been fixed.
Automatic Homogeneity Testing
Most CGE models are homogeneous degree zero in prices and quantities. The automatic homogeneity testing is one method for checking the homogeneity, real or nominal, of a model. Two kinds of tests are available, a pre-simulation homogeneity check of equations and a homogeneity simulation for testing simulation results. In both cases results of the test are summarized for the user.
To prepare a model for automatic homogeneity testing the user:
Specifies the VPQType (Value, Price, Quantity, None or Unspecified) of variables. Several methods are provided which minimize the effort required by the user.
Specifies the original level (ORIG_LEVEL=...) for ordinary change variables.
Includes one of the following commands in a CMF file
homogeneity check = real ;
homogeneity check = nominal ;
homogeneity simulation = real ;
homogeneity simulation = nominal ;
ViewHAR and ViewSOL improvements
when displaying mappings ViewHAR now shows elements of the domain and codomain sets
in ViewHAR keyboard combinations allow the user to select active sets (CTRL + LEFT, CTRL + RIGHT) and elements of active set (CTRL + UP, CTRL + DOWN)
new menu items in ViewHAR and ViewSOL open explorer or CMD exe in current folder
in ViewHAR and ViewSOL, while viewing the Contents screen or data, typing activates a quick search in the current column
CTRL + X copies the contents of a single cell from ViewHAR and ViewSOL
