The online part of the 23rd Annual Short Course in Global Trade Analysis was amazing. It is a great tool to learn about CGE model, GTAP, OneGTAP, RunGTAP and GEMPACK framework. I am looking forward to the onsite part and will use the GTAP framework in my PhD thesis.

The course will provide an invaluable opportunity to deepen my CGE modelling skills and meet other researchers in the field. This will serve me as I complete my PhD and return to work at the New Zealand Ministry of Foreign Affairs and Trade.

Dr. Chris Bachmann is an Assistant Professor in the Department of Civil and Environmental Engineering at the University of Waterloo in Waterloo, Canada. He is primarily interested in studying the interaction between transportation and economics, infrastructure economics, and engineering economics. He is part of an ongoing project to assess the impacts of Free Trade Agreements (FTAs) on Canada’s transportation system. Chris is participating in the GTAP Short Course to improve his capabilities of modelling tariffs and non-tariff barriers associated with FTAs.

Fernando Perobelli
Full Professor
Federal University of Juiz de Fora

Nowadays we have a world more connected. Thus in order to better understand this connection from the economic view I decide to participate in the GTAP Course. As a Professor at the Department of Economics of Federal University of Juiz de Fora, this course will improve the way I teach and my research agenda. I hope that after the trainning I will be able to implement models to better understand the position of Brazil in the Global Trade.

The dynamic interrelationship among trade and energy and its influence on the environment has become one of the most challenging topics in international trade and world development today. Trade liberalization and industrialization affect changes in energy consumption and production. These activities tend to produce more pollutants that cause environmental degradation. The effect of trade liberalization on the environment can be directly linked to energy consumption. I will be using the knowledge gain from this GTAP short course to my doctoral thesis on “Effect of Trade Energy Nexus on the Environment: A Case Study of Sri Lanka”. The purpose of my study is to examine the interrelationship between trade, industrialization, energy and environment and to examine how policies to address these cases affect on economic indicators in Sri Lanka under a general equilibrium framework. Environmental and energy policy issues together with trade and industrialization in Sri Lanka have received limited attention in analyzing with the GTAP model. In this context, GTAP applications on trade and industrialization, energy and environment will address the gaps in the literature. Also, it has the potential to make a significant contribution to informing the policy debate regarding trade, industry, energy and environmental policy in Sri Lanka.

Development of the GTAP Land Use Data Base for 2011

by Pena Levano, Luis Moises, Farzad Taheripour and Wally Tyner

The GTAP land use data bases provide data on land cover items including accessible forest, pasture, cropland, inaccessible forest, shrubland, savannah, and build up land areas at the Agro-Ecological Zone (AEZ) level by country. In addition, they provide data on harvested area and crop production at the AEZ level by crop and country. Avetisyan et al. (2011) documented all the data sources, methods, and assumption used in developing land use data bases for 2001 and 2004. Those data sources, methods, and assumptions were used to generate a land use data base for 2007 as well (Avetisyan, Baldos, and Hertel 2011).

To develop a land use data for 2011, we encountered a major obstacle. We do not have available the spatial global land cover data for 2011 by AEZ and country, which was available for the development of the previous versions of the data set (Ramankutty 2012). The gridded data base by Ramankutty (2012) cover a long time period starting from 1700 and ending in 2007. In order to solve this problem, we use the FAOSTAT data base developed by the Food and Agricultural Organization (FAO) of the United Nations. Currently, this data base provides land cover data at the country level up to 2011. Details

2015 Alan A. Powell Award

Mr. Anders Aeroe Mr. Anders Aeroe
Director, Division of Market Development
International Trade Centre

Anders joined the ITC in 2011 – just one year before the GTAP Conference in Geneva. This was just about the time the individual championing the 2012 Geneva Conference left the ITC. It was suddenly realized that the success of the entire conference was at risk. Anders, together with colleagues at the WTO and UNCTAD stepped into the breach to ensure that this would go forward. Anders hosted the Board meeting at the ITC, and he, along with Mondher Mimouni, set aside ITC resources to give the Board a hands-on introduction to the ITC tariffs data base. This was a real confidence-builder and proved to be an inflection point in the relationship between the ITC and the Consortium, as well as the network at large.

Lifetime of Service to the GTAP Advisory Board

Will Martin Will Martin

The 2015 GTAP Advisory Board Meeting was a very special meeting for a few reasons. First, being in Melbourne, Alan Powell was able to attend. Second, the meeting was hosted by the Productivity Commission, which was one of four founding Board Members. The Productivity Commission’s representative at the time was Philippa Dee -- Patrick Jomini’s boss! So there is great continuity here. Indeed this continuity has been one of the greatest strengths of GTAP and there is no greater symbol of continuity on the GTAP Advisory Board than Will Martin, who was recognized for his "lifetime" contribution for service on the GTAP Advisory Board.

GTAP in the News

Studies, stories and more by GTAP Network members using GTAP data.

The Economist
A weighting game

A May 30 article in The Economist highlights the differences across studies of the proposed Trans-Pacific Partnership (TPP) agreement, all of which are based on the GTAP Database. Referring to GTAP database as "the best database available," the article suggests that there are blind spots in CGE modeling, linked in part to the level of disaggregation of the databases used for these studies. The Economist also cites a paper by Narayanan, Ciuriak, and Singh (2015) that reviews these and other studies related to the TPP. The article also stresses the strengths of using CGE models for analyzing agreements such as the TPP, notably for their comprehensiveness. Other studies cited in the article include Petri, Plummer and Zhai (2014), "The TPP, China and the FTAAP: The Case for Convergence" and Ciuriak and Xiao (2014), "The Trans-Pacific Partnership: Evaluating the 'Landing Zone' for Negotiation".
