I noticed most international student collaborations are in tech… why isn’t there something similar for economics?

I am an economics student, and I have noticed that many university clubs with strong international collaborations tend to be in the tech, robotics field. It made me wonder why similar global networks are not as common among economics societies?

I have recently been working on a small international network between economics clubs, which made me realize how difficult coordination and outreach can be.

Could it be related to incentives, network effects, or coordination problems between student organizations?

More generally, what factors make it difficult for groups like university societies to form international networks, even when there seem to be clear benefits?
