Economists from Paris, Geneva, Ethiopa and other countries meet for landmark global trade meeting at Purdue
June 2017 - WEST LAFAYETTE - More than 225 leading economists and policy makers, including representatives from the World Trade Organization, various United Nations and government offices and other leading international institutions and universities, are convening at Purdue University for the 20th Annual Conference on Global Economic Analysis through Friday.
RCEP and its potential impact on textile and apparel trade
June 2017 - The Regional Comprehensive Economic Partnership (RCEP) has the potential to be one of the most significant mega-FTAs in the world, both economically and politically. And as Dr Sheng Lu, assistant professor at the Department of Fashion and Apparel Studies at the University of Delaware explains, the implications for the textile and apparel trade are enormous.
More than 200 economists and policy advisers from around the world gather for landmark global trade meeting
May 2017 - For many people, the Great Recession of 2007-09 was an unwelcome revelation as to how interdependent global economies had become. The economic downturn in the United States triggered economic slowdowns in many countries. As The Economist noted in a 2009 article, "a downturn anywhere would become a downturn everywhere." Yet, that reality had long been recognized by leading economists and researchers. That's why many of them find more significance in the upcoming 25th anniversary of the Global Trade Analysis Project (GTAP), a collaboration of more than 15,000 researchers in 170 countries that revolutionized the analysis of trade policies and their global impact.
Purdue Global Trade Conference Drawing 200-Plus Economists

Should corn growers be nervous about Donald Trump?
April 2017 - There are a few sacred cows in midwestern politics - fried foods, state fairs, manufacturing jobs - but lately, the most untouchable of them has been ethanol: ensuring that the fuel made from midwestern corn continues to be pumped into cars around the country.
Newly released Journal of Global Economic Analysis provides rare open access to innovations in applied general equilibrium modeling
March 2017 - Purdue University's Thomas Hertel, a distinguished professor of agricultural economics, recently announced the publication of the Journal of Global Economic Analysis, Vol. 1, No. 2, a free resource that gives economic researchers, government officials and students invaluable insights based on a shared global database.
Audu Ogbeh: Taking The Giant Leap To Reposition Agricultural Sector
March 2017 - According to the Oxford Business Group report of 2016, the Agricultural sector in Nigeria is performing solidly well. The report states that the sector grew at the rate of 3.48% in the fourth quarter of 2015 and a full year of 3.72% well above general economic growth of 2.11%. Blessed with abundant land and water resources, Nigeria's agricultural sector has a high potential for growth, but this potential unfortunately has never been realized until recently.

How would end of NAFTA affect US apparel industry?
November 2016 - President-elect Donald Trump has made no secret of his dislike of the North American Free Trade Agreement (NAFTA) between the US, Mexico and Canada. But far from bringing back 'Made in USA'; manufacturing, withdrawing from the pact would hurt US textile exports and do little to curb apparel imports, according to an analysis by Dr Sheng Lu, assistant professor at the Department of Fashion and Apparel Studies at the University of Delaware.
Purdue professor speaks at Vatican conference on economics and society
September 2016 - Purdue agricultural economist Dominique van der Mensbrugghe spoke Sept. 21 at a conference on economics and inequality hosted by the Vatican.

September 2016 - Biomass-based fuels present a tremendous opportunity to transition toward a more sustainable mix of renewable energy. This was a key theme of an alternative fuels workshop hosted Sept. 14 by the U.S. DOE in Macon, Georgia. The workshop examined the sustainability of feedstocks like soybean oil, which can be used to make biodiesel or alternative jet fuel.
Big Canadian GDP boost from unilateral trade liberalization: study
August 2016 - Provided the Canada-EU trade agreement and the Trans-Pacific Partnership are brought into force and the Liberal government pursues bilateral negotiations with China - all of which, it needs to be said, are very far from certain - Canada would have free trade with its 13 biggest trading partners.
The welfare impacts of foreign agricultural investment in Sub-Saharan Africa
May 2016 - The increasing involvement of foreign investors in Sub-Saharan Africa's agricultural sector, especially through the so-called "land grabbing" phenomenon, has stirred passionate debates among analysts, policymakers, and stakeholders alike. Host countries hope that foreign agricultural investment will provide employment opportunities leading to increased purchasing power and tax revenues from payroll and eventually on profits. From these investments, host countries also expect added benefits such as enhanced skills, new or improved infrastructure, and faster technology transfer. However, one important concern is that foreign agricultural investment may worsen the problem of food insecurity in SSA by raising food prices and increasing food imports. Likewise, some fear that agricultural investment leading to changes in factor input use may reduce the competitiveness of domestic sectors such as food and services. Consequently, is foreign agricultural investment in SSA something to fear or to hope for?
USITC Releases Report on the Trans-Pacific Partnership (TPP) Agreement
April 2016 - On May 19, 2016, the U.S. International Trade Commission (USITC) released its report assessing the likely impact of the Trans-Pacific Partnership (TPP) Agreement that the United States has negotiated with Australia, Brunei Darussalam, Canada, Chile, Japan, Malaysia, Mexico, New Zealand, Peru, Singapore, and Vietnam. The USITC's report, Trans-Pacific Partnership Agreement: Likely Impact on the U.S. Economy and on Specific Industry Sectors, provides an assessment of the likely impact of the Agreement on the U.S. economy as a whole and on specific industry sectors and the interests of U.S. consumers, as requested by the U.S. Trade Representative and required by the Bipartisan Congressional Trade Priorities and Accountability Act of 2015. The report's quantitative assessment relies on a GTAP-based dynamic general equilibrium model.
Eliminating GMOs would raise food prices
March 2016 - WEST LAFAYETTE, Ind. - If genetically modified organisms in the United States were banned, consumers could expect higher food prices. There would also be a significant boost in greenhouse gas emissions due to land use change and major loss of forest and pasture land, according to a recent Purdue University study.
Global Trade Analysis Project studying climate change
February 2016 - Mark Dorenkamp from Brownfield Ag News spoke with Tom Hertel about GTAP, the endeavor he founded in 1993.
Study: Eliminating GMOs would take toll on environment, economies
February 2016 - The main objective of this study was to evaluate what would be the economic and environmental consequences of losing the GMO traits in the U.S. for the major crops of corn, soybeans and cotton. The first step was to obtain from the literature a range of estimates of the yield losses if we move away from GMO traits in the U.S. The second step was to introduce the yield losses obtained in the first step into a well known CGE model, GTAP-BIO, to quantify the land use and economic impacts of banning GMO traits in the U.S.
Market integration could help protect poor from climate-related food insecurity

A weighting game, Pacific trade talks expose the limits of economic modelling
May 2015 - THE Trans-Pacific Partnership (TPP), a putative trade agreement, would ease commerce between America, Japan and ten other countries that between them account for two-fifths of global GDP. But how beneficial would it be to these economies? Advocates claim it would boost their output by nearly $300 billion in a decade. Critics say it would make little or no difference.

USDA TPP Study Shows Smaller Hit On Japan Ag Sector Than Tokyo Predicts (requires subscription)
November 2014 - "A new study by the U.S. Department of Agriculture (USDA) concludes that the elimination of all tariffs on farm goods under a Trans-Pacific Partnership (TPP) agreement would be less damaging to Japan's agriculture industry than the Japanese government has predicted, due to a range of factors."
Study: Real-world data casts grave doubt on land use models
November 2014 - A comprehensive analysis of real-world land use data recently released by Iowa State University raises serious doubts and concerns about the reliability and accuracy of economic models used by regulatory agencies to penalize ethanol for purported "indirect land use changes," or ILUC. The new report found that farmers around the world have responded to higher crop prices in the past decade mainly by using existing land resources more efficiently-not by converting forest and grassland into cropland.
Are Genetically Modified Crops Good for Sub-Saharan Africa? An Overview
June 2014 - USA RIVER, TANZANIA - Sebastian Mushi, or "Seba," as he is known around here, owns an agricultural business in Usa River, Tanzania. In his bare-bones shopfront he stocks chemical fertilizers, pesticide sprays, and an assortment of maize and rice seeds. Perched comfortably on a bag of maize is Seba's friend and rice farmer, Ramadan. While he waits for his phone to charge, Rama recounts how he took Seba's advice to use a combination of hybrid seeds, fertilizers, and pesticides for his rice paddies and watched his farm's productivity bloom this season. Pleased with the profitable results, Rama has shared his success story with many other farmers who have since followed suit.

Cutting livestock greenhouse gases requires effort from rich and poor countries
November 2012 - "Regulating livestock greenhouse gas emissions could shift livestock production to unregulated, less developed countries unless those poorer nations can be enticed to preserve their forested lands, according to a Purdue University economic study."
Global trade program celebrates 20-year anniversary
October 2012 - "A Purdue University-based program that helps researchers and policymakers analyze international trade is turning 20 years old. The Global Trade Analysis Project maintains data on more than 948,000 bilateral trade flows linking 130 economies around the world. GTAP is housed in Purdue's Department of Agricultural Economics."
Climate Change to Affect Corn Prices, Study Says
April 2012 - "Researchers have found that climate change is likely to have far greater influence on the volatility of corn prices over the next three decades than factors that recently have been blamed for price swings - like oil prices, trade policies and government biofuel mandates. The new study, published on Sunday in the journal Nature Climate Change, suggests that unless farmers develop more heat-tolerant corn varieties or gradually move corn production from the United States into Canada, frequent heat waves will cause sharp price spikes. Noah S. Diffenbaugh, a climate scientist at Stanford and an author of the study, said he was surprised by the notable effect of climate change on price volatility for corn, the country's largest crop. "I really thought climate would be a minor player before we did this analysis," Professor Diffenbaugh said. "We're looking at a period over the next three decades or so of moderate global warming, after all."
Database of global economic information is expanded
March 2012 - "A database of worldwide economic information used to evaluate trade agreements between nations has been expanded to include data from 15 more countries in an updated version released by Purdue University. The Global Trade Analysis Project, a global network of researchers and policy-makers who analyze international policy issues, includes data on bilateral trade patterns and production, consumption and intermediate use of commodities and services. It is used by governments, international institutions, the private sector and economists at universities..."
Is Canada's economy really dependent on global trade?
January 2012 - Currency traders love the monthly import and export data, which provide an excellent guide of how much demand exists for dollars, euros, yen, francs and the like. But for anyone seeking a more precise understanding of the dynamics of international trade, the data compiled by customs agents are about as about as relevant to a modern economy as carbon paper.

Agriculture and Long Run Sustainability
October 2011 - "For the past 200 years, ever since Thomas Malthus published his Essay on the Principle of Population, big thinkers have been wondering whether Earth-dwellers will eventually run out of food. Today, a global group of scientists released a fresh look at the question. They add a different, environmental twist to it. Can we feed the world without destroying the environment? What we have instead of a dictator is the global marketplace, setting prices for land, corn, meat, and everything else. Those prices drive decisions by farmers. But Thomas Hertel, an economist at Purdue University, says those markets can help solve our planetary problem - especially if we step in to make those markets work better..."

Climate Change Could Deepen Poverty In Developing Countries, Study Finds
August 2009 - Urban workers could suffer most from climate change as the cost of food drives them into poverty, according to a new study that quantifies the effects of climate on the world's poor populations. Researchers examined the potential economic influence of adverse climate events, such as heat waves, drought and heavy rains, on those in 16 developing countries. Urban workers in Bangladesh, Mexico and Zambia were found to be the most at risk.

Poverty and the WTO: Impacts of the Doha Development Agenda
December 2005 - "During the 2004/2005 academic year, Thomas Hertel was on sabbatical with the International Trade Research Group of the World Bank during which time he directed a major international research project aimed at analyzing the poverty impacts of the prospective Doha Development Agenda (DDA) currently under negotiation at the WTO in Geneva. This involved several global analyses based on the GTAP framework. It also linked these global analyses to a dozen country case studies conducted by research teams in Asia, Africa and Latin America. The project showed that previous estimates of the likely poverty reductions were likely overstated, but more importantly, it highlighted ways in which the prospective DDA could be made more poverty friendly. Dr. Hertel was called upon to present this work in Geneva, Paris, Brussels, Mozambique, South Africa, Brazil and Washington, D.C. His two trips to Geneva also involved informal discussions with lead trade negotiators in the WTO. The ensuing book will be published in early December-just before the Hong Kong Ministerial of the WTO. It was also featured prominently on November 16 in the Financial Times of London.
Weighed in the balance
December 2005 - The Doha round of world trade negotiations was supposed to lift many millions out of poverty. It looks unlikely to do so. Launched in a spirit of global solidarity two months after the terrorist attacks of September 11th 2001, the Doha round of global trade talks has always been billed as being about more than just trade. Its official title is the "Doha Development Agenda". Its purpose, as Tony Blair recently put it, is "to create the conditions in which millions of people will have a chance to escape poverty". Such lofty aspirations are sure to be given voice often in Hong Kong this week, when the world's trade ministers meet with the aim of reviving the flagging negotiations. Whether the Doha round will live up to those aspirations is less certain. This is not only because the talks are stalled. Perhaps more important, the benefits of the round to the world's poorest people have anyway been overstated. And most important of all, neither developed nor developing countries have been ambitious enough to seek the degree of trade liberalisation needed to help the poorest..."
