Economics of Networks

The economics of networks is a thriving new field. Rachel Kranton's papers develop formal models of networks in different economic settings.  She studies the costs and benefits of informal exchange, which is economic activity mediated by social relationships rather than markets. Her work draws on empirical findings and integrates new mathematical tools to uncover how network structures influence economic outcomes.  The economics of networks is part of a larger emergent field of network science, which spans may disciplines including computer science and information science.

Rachel Kranton, along with collaborators Yann Bramoullé and Deborah Minehart, has studied buyer-seller networks, risk-sharing networks, and network public goods. Her current work focuses on strategic interaction and innovation. Main findings include:
