Studies, stories and more by GTAP Network members using GTAP data.
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.
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.
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.
March 2017 - Study shows extent to which US and western European demand for clothes, toys and mobile phones contributes to air pollution in developing countries
February 2017 - The Trans-Pacific Partnership among 12 nations (TPP12) was thrown into disarray after President Donald Trump pulled the United States, the largest economy in the grouping, out of what was to be a landmark trade deal. Presently, a number of remaining TPP members including Australia, New Zealand, Chile and Singapore are making the case for a trade pact without the US, dubbed TPP11 or "TPP 12 minus one".
February 2017 - Wally Tyner, a professor in Purdue's Department of Agricultural Economics, said he has his work cut out for him exploring the economics of cover crops. There are so many variables and so little history. The study is a collaborative effort with the Farm Foundation.
December 2016 - Three new studies illuminate the sheer complexity of the aspect of climate science known as the carbon cycle − how carbon dioxide gets into the atmosphere and out again.
December 2016 - Arguments that policies such as NAFTA have killed American manufacturing jobs often ignore the many other American jobs that such deals create and support.
December 2016 - The United States and Mexico shared a maritime and land border in North America. They have always been an allied despite facing trials and changes of government. The countries are becoming stronger and more triumphant working together.
December 2016 - Free trade means giving people and private enterprises the freedom to produce more commodities that consumers demand at certain prices. These producers then leave sectors and areas where expected returns and other gains are lower if not dwindling.
December 2016 - Oil extended the longest winning streak in more than four months before Opec and other producing nations start reducing output to stabilise the market.
November 2016 - WEST LAFAYETTE, Ind. - A global ban on genetically modified crops would raise food prices and add the equivalent of nearly a billion tons of carbon dioxide to the atmosphere, a study by researchers from Purdue University shows.
November 2016 - Eight Purdue University professors, including GTAP's own Wally Tyner, have been awarded the distinction of fellow from the American Association for the Advancement of Science, the world's largest general scientific society. The professors are being honored for their efforts toward advancing science applications that are deemed scientifically or socially distinguished. *Wallace E. Tyner, James & Lois Ackerman Professor of Agricultural Economics in the College of Agriculture - For distinguished contributions in agricultural and energy economics and research at the interface of the two areas, especially biofuels economics and policy.
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.
September 2016 - Purdue agricultural economist Dominique van der Mensbrugghe spoke Sept. 21 at a conference on economics and inequality hosted by the Vatican. He spoke alongside Nobel Prize winner Angus Deaton and professor Jean-Paul Fitoussi of Rome's LUISS Guido Carli University in the Vatican's Courtyard of the Gentiles.
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.
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.
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?
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.
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.
February 2016 - Mark Dorenkamp from Brownfield Ag News spoke with Tom Hertel about GTAP, the endeavor he founded in 1993.
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.
February 2016 - Agricultural Communication Service writer Natalie van Hoose talked with GTAP's very own Thomas Hertel about his talk, "The Underlying Climate Mechanisms of International Food Trade," part of the "Climate Change and Agriculture: Revisiting the Evidence and Potential Solutions" symposium.
September 2015 - Vietnam will gain the most substantial gross domestic product (GDP) increase in percentage terms of any other economy upon implementation of the ASEAN Economy Community (AEC) and Trans-Pacific Partnership (TPP) in almost all scenarios projected by the Vietnam Institute for Economy and Policy Research (VEPR). The VEPR report was based on the Global Trade Analysis Project (GTAP) databases, giving the first quantitative assessment of the impact of the AEC and TPP on Vietnam. VEPR created six scenarios from the data.
August 2015 - The Ag Research Spotlight shines each month on an individual whose work reflects our commitment to the six strategic themes that guide Agricultural Research at Purdue.
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.
May 2015 - The Center for Global Trade Analysis based at Purdue University released the latest version of its GTAP Data Base of worldwide economic transactions Tuesday (May19).
March 2015 - Using models that blend global economics, geography, ecology and environmental sciences is essential to understanding how changes in trade and natural systems in one part of the world affect those in another, a review concludes.
January 2015 - A world perspective on the short and long-run impacts of food price changes on poverty will be up for discussion at a major international economics conference in Rotorua next month.
December 2014 - World Bank working paper using GTAP data and cited by the Financial Times and Al Jazeera
December 2014 - "A government-appointed group of top nutrition experts, assigned to lay the scientific groundwork for a new version of the nation's dietary guidelines, decided earlier this year to collect data on the environmental implication of different food choices."
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."
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.
October 2014 - Covered by the Financial Times
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.
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."
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."
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."
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..."
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.
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..."
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.
May 2009 - The Obama administration has given the biofuels industry a major boost. It's providing the agro-energy industry with nearly three quarters of a billion dollars and proposing new rules to help accelerate development of advanced fuels. Host Steve Curwood talks with Jim Lane, publisher and editor of BioFuels Digest about the future of biofuels.
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.
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..."
