About GTAP

Founded in 1992, and coordinated by the Center for Global Trade Analysis at Purdue University, the Global Trade Analysis Project (GTAP) is a network of 32,553 individuals engaged in quantitative analysis of 21st century challenges. A consortium of 31 leading national, international, and private institutions provides baseline financial support and strategic advice to the Center for Global Trade Analysis in support of GTAP. Guided by a philosophy of collaboration in domains of mutual benefit, notably data development, combined with an open marketplace for ideas in analytics, GTAP aims to advance high-quality quantitative analysis of global issues and facilitate deliberate decision-making. To this end, GTAP:

  1. Lowers barriers for conducting high-quality analysis of global issues

    Data - GTAP assembles, documents, and makes publicly available a suite of databases that are widely regarded as the gold standard for global economywide analysis.
    Models, tools, and software - GTAP develops and makes publicly available a suite of cutting-edge and fully documented models and tools and collaborates with leading analytical software providers and the open-source programming community in the application of those models.
    Training - GTAP offers regular training courses, ranging from introductory to advanced, to scaffold network members in the application of the data, models, and software.

  2. Conducts research on pressing issues with global ramifications

    While the bulk of GTAP-related research is conducted by GTAP Network members, the Center for Global Trade Analysis houses one of the largest groups of top-flight economywide modelers in the world. This unique concentration of skill is buttressed by sector expertise, notably in energy and food systems. Guided by a distinguished Scientific Council, GTAP researchers, often in collaboration with network members, address a range of issues including trade and industrial policy, energy transitions, climatic change, economic development, biodiversity preservation, pollution abatement, and the circular economy.

  3. Serves as a platform for discussion and dissemination of novel approaches and new ideas

    GTAP brings together thought leaders at the Annual Conference on Global Economic Analysis, fosters innovation through the peer-reviewed Journal of Global Economic Analysis, hosts a Virtual Seminar Series, and maintains an active presence on social media.

GTAP-related analytics are a regular feature in the world’s most prestigious scientific journals and inform a vast array of decision-making processes by governments, international organizations, and private entities around the world.

How Trump's tariffs could hit developing economies - even those not involved in the trade war
May 2025 - The world has witnessed a resurgence of protectionism since Donald Trump returned to the White House. So-called "reciprocal" tariffs, imposed on all US trading partners at varying degrees based on the tax they charge on American goods, have been one of the hallmark features of Trump's economic policy. They aim to correct what he perceives as "unfair" trade practices.

Trump's tariffs: Challenge or opportunity for Jordan in global trade arena
April 2025 - US President Donald Trump's decision to impose new tariffs on a range of countries triggered significant debate in global economic and trade circles. US public opinion polls showed that 61 per cent of Americans believed the tariffs would negatively impact consumers, compared to only 14 per cent who expected a positive outcome. The decision included a general 10 per cent tariff on all imports, with a specific 20 per cent tariff imposed on products from Jordan. This was justified by claims that Jordan imposes a 40 per cent tariff on American goods, but closer analysis suggests the true goal was to address the US trade deficit, not to match existing foreign tariffs.
