Globalization can be most concretely captured in an investigation of global economic networks. In this essay, we review foundational and cutting‐edge research on global economic networks, including economic ties that result from trade, investment, finance, and remittance relations between corporations and/or citizens from different nations; through flows of people due to migration and global tourism; and via international institutions that govern global economic exchange. We focus on research that examines the determinants and consequences of global economic ties from different theoretical perspectives, such as neoclassical economics, the world‐systems research, global commodity chains, regionalization, and world society perspective. We also review research that maps the structure of the global economy. We end by identifying promising venues for future research.
