GTAP Events: 11th Annual Conference on Global Economic Analysis: Organized Sessions

The following organized sessions have been accepted into the conference.


Integration of micro data information in CGE models
Organized by: Stefan Boeters

There are several fields in CGE modelling where micro data is used to complement and enhance national account data for getting a ritcher and more comprehensive picture of the issue at hand: poverty analysis, labour market reform, consumption patterns.

Agricultural Price Distortions, Inequality and Poverty: National CGE Studies
Organized by: Ernesto Valenzuela

Government interventions alter price incentives to agricultural production. Interventions can be direct agricultural policies or import protection schemes in non-agricultural production. Given that agriculture represent the main production activity for the vast majority of poor, understanding how those policies alter poverty levels and in general the distribution of income can shed light on the political economy forces behind policy intervention.

Global trade policies, Inequality and Poverty
Organized by: Kym Anderson

Agricultural producers face price incentives that have been distorted by government policies at home and abroad, and by direct agricultural policies as well as indirectly by import protection and the like for producers of non-agricultural tradables. Understanding how those policies alter the distribution of income can shed light on the political economy forces behind their introduction and maintenance. Such analysis can also show how those policies affect income inequality and poverty. The expectation is that in the long run distortionary policies reduce economic growth and thereby contribute to poverty, but their impact is less obvious in a comparative static, short-run sense. True, farm earnings and wages of unskilled labor would tend to rise with agricultural prices, but so too would the cost of food consumption. Whether the earnings net of taxes of wage-earners and even some farmers who are net buyers of food go up more than their expenditures is a question that can only be answered empirically (Winters, McCulloch and McKay 2004). The need for such answers is clear from the controversies that arise when economic institutions whose mandate it to reduce global poverty clash with civil society groups who seek the same outcome (Kanbur 2001).

Modeling Global Effects of Biofuel Development and Production
Organized by: Utpal Vasavada

An expansion of biofuel production has led to a significant diversion of crops such as corn, soybeans and others from livestock feeds to ethanol. Similar situation has been occurring in Brazil as more sugar cane is being produced for sugar-based ethanol. Economists have found very quickly that most existing agricultural models lacked the necessary components and data to be useful. This exposed a need to improve the current analytical modeling frameworks and data systems to examine biofuels.

Tariff-line Analysis
Organized by: Thomas Hertel

Given that most of the policy decisions and trade negotiations take place at tariff-line level, it is imperative to overcome the aggregation bias of the CGE models used for trade policy analysis. This session is an earnest step towards this direction. There are three papers in this session. The first presentation introduces the new TASTE database that is built based on MacMAP database comprising data at HS6 level. The second one explains the importance of analysing trade liberalisation at product-level. The third paper illustrates the usefulness of linking PE with GE, by making use of MacMAP and GTAP, focussing on textile/apparel sectors in developing countries.

Presented by: Laborde, David




Growth and Poverty
Organized by: Christian Arnault Emini

This session is composed of four presentations focused on the growth and poverty links, along with the poverty and growth effects of various economic policies in developing countries. Microsimulation CGE models are used as the main methodology device. But they are built with various specificities and mixed with other techniques like double-calibration and econometrics. The policies considered are trade liberalization, devaluation, infrastructure investments, tax and costums policies. The theme of this session is of high importance nowadays, when the question is to dig down the propoor significance of growth, the quality of growth, the ability of growth and growth-conducive policies to really alleveiate poverty and help achieve Millenium Goals.

Duct tape or theory? A practitioners’ discussion on linking of models with a focus on agriculture
Organized by: Frank van Tongeren

Answering a call for more detailed assessment without losing sight of the bigger picture, linking of models has become increasingly popular. The common thread in this session is that a GTAP (style) model is linked to an agricultural model. The reason for linking an agricultural model is that the way in which agricultural is modeled in GTAP is deemed insufficient for the research question at hand.

Chinese Economy
Organized by: Shantong Li

P. R. China is a large developing country with a huge population and a tremendous amount of territory. Among the regions, the natural endowments as well as economic and social conditions differ greatly. Recently multi-regional CGE models have been constructed and used to analyze the economic, social, and environment issues in China, such as structure change, labor mobility, energy, environment, etc. This session will focus on development of Chinese multi-regional CGE models and its application.

Trade and integration in Africa
Organized by: Antoine Bouët

In debates about globalization, Africa’s ability to take advantage of trading opportunities has always been under contention. Data indicate that the continent’s share of world exports has declined sharply, from about 5.5 percent in 1975 to about 2.5 percent in 2002 (source: World Development Indicators). This session is aimed at studying the various forms of Africa’s integration in world trade (North-South regional agreement, South-South regional agreement, and multilateral liberalization) and the attached virtues and drawbacks of each of these options. Finally as a lack of domestic infrastructure is often pointed out as responsible for African failure to trade, the session also looks at the role of transportation and telecommunication infrastructure.

Climate Change-Impacts, Mitigation and Distribution
Organized by: Dominique van der Mensbrugghe

The global community is gearing up for negotiations on a new protocol to succeed the Kyoto Protocol. It is clear--as evidenced by the discussions at Bali--that developing countries will play a much greater role in these negotiations than in the past. The success or failure of these negotiations will depend to the extent that a broad group of countries can overcome a possible wide-range of opposition to any imposition of emission limits--be it at the national, sectoral or special interest group level. The papers in this session are intended to highlight some of the political economy aspects of a Kyoto Protocol successor by identifying potential gainers and losers from any new Protocol and assessing potential compensation mechanisms and policy designs that can minimize the potential losses.

Organized Session: Biofuels and Climate Policy
Organized by: Steven Rose

While there has been a great deal of attention focused on biofuels mandates, and their impacts on food and fuel markets recently, there has been relatively less attention devoted to the interactions between biofuels policies and climate policies – specifically carbon emissions and the cost of GHG mitigation. The three papers in this session tackle this issue in various ways. In the first paper, the authors consider how the US and EU biofuel mandates are likely to affect GHG emissions, and also how they are likely to affect the GHG mitigation potential of land-using sectors. The second paper looks at the interaction between biofuels mandates in the EU and the European carbon trading system. It also explores the impacts of free trade in biofuels. Finally, the third paper focuses on land supply and how this affects the decision to convert land, as well as the resulting implications for carbon emissions. The last paper also considers the impacts of environmental change on biofuels opportunities.

Examining the Impacts of Biofuel Mandates
Organized by: Wally Tyner

This session examines the impacts of US and EU biofuels mandates from three different perspectives. The first paper (van Meijl et al) focuses on the global impacts of EU biofuels policies and with respect to both first and second generation biofuels. The second paper (Birur et al) examines the interaction of US and EU biofuels policies and examines global implications of US and EU policies alone and in combination. The third paper (Taheripour et al) is also a global policy impact analysis but focuses more on the importance of incorporating biofuels co-products into our analysis. Taken together the papers provide very useful analysis and information on the impacts of US and EU biofuels mandates.

Measuring the Economic Impacts of Trade Facilitation
Organized by: Peter Minor

World trade has grown rapidly in recent decades, but goods do not yet flow freely from place to place. The large majority of firms serve only domestic markets, and among firms that do export only a small portion of sales is to foreign customers. National borders themselves appear "thick." For example, McCallum (1995) showed that the quantity of trade between Canadian provinces was about 22 times greater than trade between Canadian provinces and U.S. states of similar size and distance. Why don't countries trade more? Discussions of trade barriers usually focus on tariffs, but average import tariffs worldwide dropped from 8.6 to 3.2 percent between 1960 and 1995(Clemens and Williamson 2002). Perhaps nontariff barriers are the primary obstacle s to trade? This organized session examines a particular type of nontariff barrier: trade facilitation-the support a country provides in facilitating the movement of goods across borders including customs, port facilities and procedures and inland transport. The discussion will be organized around current state of knowledge and extending research to better estimate economic and trade impacts with an eye towards constructively informing policy makers and stakeholders.
