Ask HN: Relation b/w Economic Performance and Size of Countries

HNers, if you have any research you can point to that correlates economic performance with the size of countries, I'd love for you to share it here.

It's a convoluted subject for sure, but the thought experiment here is - can fast information channels and troves of digital data lead to convergence in our physical world in terms of law strucure, economic policies, etc on a macro level in concert with existence of smaller countries with hyper-focused growth strategies and well-hydrated human/material supply chains connecting them?

We do not need to go down the rabbit hole by asking what the definition of a country is, and can assume that it's a geographically locked piece of land with uniform laws and a well-defined governance model.
