While economic modeling techniques have become an increasingly important component of policy analysis in government ministries, research institutes, and in academia, formal training in particular tools has been relatively limited. However, improved capacity building in modeling techniques is an important component in enhancing the quality of decision making at a policy level and in conducting state-of-the-art academic and policy research.
This course provides intensive training in the use of different economic modeling tools, including multi-market models, in the context of biofuels production and policies. The course is motivated by the recent rapid global expansion in the demand and supply of crop-based biofuels production, which is reshaping agricultural markets by linking food prices to energy prices. Such growth in biofuels can be both alternately viewed as a beacon of hope or a message of despair for the world’s billion poor people – with little existing quantitative analysis to support either position.
The four-day course combines a review of economic theory and practical modeling approach with training in GAMS to provide participants with the basis to utilize such tools in their own research. By the end of the course, participants will be able to:
(i) understand the basics of partial-equilibrium multi-market analysis
(ii) independently develop a structure for a multi-market model;
(iii) have knowledge in data requirement for developing multi-market model;
(iv) have facility in the GAMS programming language;
(v) implement a simple multi-market model in GAMS, including the design of policy scenarios to assess market responses to and welfare impact of biofuels policies in major producing countries.
Intended participants for this course are economic researchers, graduate students, and policy analysts. A background in microeconomic theory at the undergraduate level is required. Programming experience in GAMS is not necessary, though past experience with the use of computing software and other programming languages is recommended.

The recent rapid global expansion in the demand and supply of biofuels is shaping the world food economy in new and fundamental ways, linking food prices to energy prices and potentially re-writing the rules of rural development. Such growth in biofuels is alternately viewed as a beacon of hope or a message of despair for the world’s billion poor people – with little existing data to support either position.
This organized symposium addressed a number of the effects of biofuels expansion on world food markets, with an emphasis on the global poor. Papers in our session made both substantive and methodological contributions. Substantively, papers in our session sought to:
Methodologically, these papers span the spectrum of what is available in the literature. We show the differences in our models from including (or not including) the following assumptions: using a partial equilibrium framework vs. general equilibrium trade model; allowing for the expansion of land; allowing for the use of DDG; allowing for rising oil prices; and modeling the flexibility of using ethanol in the transportation fleet in the second decade of the 21st century.
Indeed, in summary, using a number of different models and a number of different approaches, there were two avenues of questions to guide the proposed work.
The symposium included representatives from five teams of economists around the world—CCAP in Beijing (Jikun Huang, Yang Jun and Qiu Huanguang); the Netherlands (Martin Banse); IFPRI (Mark Rosegrant, Siwa Msangi and Wei Zhang); two teams from Purdue (Tom Hertel); and Stanford University (Scott Rozelle and Elaine Yu).
