Earlier versions of this paper were presented at the International Agricultural Trade Research Consortium Meetings San Diego, CA, December 14-16, 1997 and at the 1st Annual Conference in Global Economic Analysis, Purdue University, June 1998 This study assesses the interaction between climate...

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...

From time to time, members of the GTAP network compare GTAP data with official statistics from national and international sources. This has recently been done for the GDP statistics in GTAP, v.8 (Wang et al., 2013), suggesting that there were significant discrepancies between GTAP statistics and...

We synthesized a range of geographically-explicit forest, grassland and cropland biomass and soil carbon input data sources and used geographic information systems (GIS) software to calculate new estimates of soil and biomass carbon stocks for use with global economic models, particularly for...

The EU Single Farm Payment (SFP) is currently distributed in proportion to primary factor shares in version 8 of the GTAP database. In this paper, we investigate whether this way of modeling the EU SFP makes a difference in analyzing agricultural policy reforms. To do so, we create alternative...

This paper documents GDyn-E CGE model developed for analysis of climate policies in dynamic GTAP framework. Description of the modeling framework is followed by a presentation of a simple application focused on emission leakage associated with a unilateral GHG abatement policy, analysis and...

The GTAP standard model has proved a useful analysis tool and data source for over 20 years. The GTAP model has been updated overtime, but it maintains the structure of a single regional household, with income distributed into three components: government, private and savings-investment...

In an attempt to control the flow of undocumented immigrants, successive US governments have considered everything from large scale deportation, amnesties, expanding visa programs, to fining firms who hire illegal workers. Using a comparative static model, Aguiar and Walmsley (2013), find that...

The prevalence of undocumented workers in the United States is a sensitive issue for U.S. policy makers with numerous policy responses contemplated by several different administrations. This paper examines the impact of possible reforms to U.S. immigration policy with respect to undocumented...
