The purpose of this note is to provide an exhaustive reference for those interested in learning more about the Constant Elasticity of Substitution (CES) function and its use in the representation of producer behavior in the GTAP Model. Particular attention is paid to the role of technical change...

The land-use augmented version of the GTAP Data Base has been used for a wide variety of applications (Hertel, Rose, & Tol, 2009). The original GTAP-AEZ database incorporated geospatial data on land use into the version 6 GTAP Data Base, with a benchmark year of 2001. The methodology for...

No one thought China’s high growth rates would persist forever, or that multinational firms would always keep pouring into the Chinese market, eager to establish operations regardless of local conditions. Economic convergence ensures that there will be a cooling off as wages rise and expected...

Year 2004 emissions were estimated by applying annual growth rates to the detailed year 2001 emissions data (Rose et al., 2007) that was the input dataset for the GTAP version 6 non-CO2 emissions (Rose and Lee, 2009). Two methodologies were applied: one for methane (CH4) and nitrous oxide (N2O),...

The purpose of this Research Memorandum is to propose an approach to incorporating forest access cost functions into global general equilibrium models such as GTAP. Towards this end, we develop a long run access cost function which can be calibrated to national data on total forest land,...

Production of liquid biofuels has rapidly increased around the world in recent years. Biofuel production, by its nature, can affect the economy and environment of many countries in different ways. Global Computable General Equilibrium (CGE) analysis is an appropriate approach to study the...

The land-use augmented version of the GTAP Data Base has been used for a wide variety of applications (T. W. Hertel, Rose, & Tol, 2009). It builds on global land cover and land use data bases documented in Monfreda et al. (2008) and Ramankutty and Foley (1999) as well as global forestry data...

An important question that arises frequently in the economic analysis of environmental and energy policies is, how does the supply of land across various uses change in response to policies? The GTAP Modeling framework of Hertel (1997) addresses this question by determining the supply of land...

While constructing a new baseline for the GDyn model, we spent a lot of time collecting projections and deciding which data to choose. We also developed programs to aggregate projections to any specific geographical aggregation of the GTAP Data Base. In order to help researchers in the...

A recent World Bank research project has generated an annual time series of distortions to agricultural incentives over the past half century for 82 countries, the majority of which are low-and middle-income countries. In this memorandum, the current GTAP version 8 Data Base may be modified to...
