Models & Modeling tools

AGRODEP provides a platform for sharing existing core economic models dealing with sector, national, and international policy issues as well as long-term projections in areas such as agricultural growth and poverty, trade, nutrition, climate change, natural resources management, and science and technology.

The shared modeling infrastructure is organized around two main pillars: simulation models and econometric models. The main goal of simulation models is to perform ex-ante analysis of various economic policies (e.g. investment decision in agricultural R&D in different sectors) or to disentangle different effects of existing policies (e.g. interaction between export taxes and import duties in international trade relations). Simulation models include Computable General Equilibrium models and Partial Equilibrium models, both in deterministic and stochastic versions. The main softwares needed to use these models are GAMS or MS Excel. 

Econometric models are mainly aimed to assess the effects of existing policies (e.g. consequences of exchange rate policies on agricultural exports) or to identify and quantify the drivers of an economic phenomenon (e.g. determinants of trade in a gravity equation). They are also used to estimate key parameters used in the simulation models (e.g. price transmission magnitude between international and domestic markets). The econometric methods used in the library include parametric and non parametric approaches. Most of the econometric programs will require the use of STATA.

The library includes models developed and fully supported by the AGRODEP team, as well as links to models developed and managed by other partners. For instance, concerning CGE models, the former category includes models such as the IFPRI Standard Model or the PEP 1-1 models, while the later include the GTAP (Global Trade Analysis Project) model.

The modeling tools will, as the Consortium progresses, be expanded to include a set of specialized modules devoted to specific technical areas and economic sectors. Such modules will be added as needed through collaboration with other leading centers of expertise to address special needs, such as in the areas of agronomy, forestry or concerning specialized topics such as the food crisis and climate change risks and adaptation.

Model Selection

In order to assist with the decision process of which model to use, AGRODEP has prepared a guide with information on some of the most popular models within the library. This user guide provides the model classifications, information on scale, dynamics, market structure, and more. We also include information on dates and data sources for easy viewing. Please review the user guide here before using our models.
