RIETI Workshop

Dynamics in Finance and Economy on economic networks


In recent years, research on economy and finance has been accelerating with usage of real data. Networks form the basic space where economic and financial phenomena, business cycles and economic crisis among others, occur. Japan is blessed with abundant real big network data, such as the production network, on which several advanced research has been done.

This workshop aims to cover these research results as well as other related issues. Some key researchers from abroad who share similar ideals are invited for high-level exchange of ideas and results.
