Indeed. Clearly, we can’t make this an experiment except in very small, poor countries. The closest I’m aware of is the GiveDirectly UBI study in Kenya. Also, note that Germany has a minimum unconditional basic income of more than 700€/month (not universal, though).
So, we cannot make the experiment, and we also can’t model the effect sufficiently well yet. But with studies like this, somebody will hopefully be able to come up with an economic theory eventually.
This doesn’t address how the equilibrium would change if such basic income becomes universal.
