Global Linkages Lab

The Global Linkages Lab is dedicated to deepening our understanding of globalization. As a collaborative research hub, the Global Linkages Lab fosters innovative scholarship, funds state-of-the-art research, and provides insights to inform evidence-based policymaking for global growth and welfare.

The Global Linkages Lab hosts a diverse range of raw and derived datasets on global trade and financial linkages, at a granular level, enabling to ignite path breaking research on issues such as global networks, tariffs and sanctions, trade and inflation, domestic and global productivity, misallocation of global capital, financing of green transition, dominance of the dollar, the global impact of U.S. fiscal, monetary and trade policies, geopolitics led global fragmentation and disengagement amidst significant global challenges. One of our primary goals is to provide a valuable public service, by sharing our data and hosting seminars and large conferences.

The Global Linkages Lab strives to help to build a diverse, inclusive and productive economics profession following the 2019 best practices report of AEA task force composed of Amanda Bayer, our director Şebnem Kalemli-Özcan, Rohini Pande, Cecilia Elena Rouse, Anthony A.
